Vector Graphics Essay Example for Free

Vector Graphics Essay Vector designs is the utilization of geometrical natives, for example, focuses, lines, bends, and shapes or polygon(s), which are completely founded on scientific articulations, to speak to pictures in PC illustrations. Vector, in this specific circumstance, suggests in excess of a straight line. Vector illustrations depend on pictures comprised of vectors (additionally called ways, or strokes) which lead through areas called control focuses. Every one of these focuses has an unmistakable situation on the x and y tomahawks of the work plan. Each point, also, is an assortment of database, remembering the area of the point for the work space and the heading of the vector (which is the thing that characterizes the bearing of the track). Each track can be allocated a shading, a shape, a thickness and furthermore a fill. This doesn't influence the size of the records in a significant manner since all data dwells in the structure; it depicts how to draw the vector. Same as item situated illustrations, alludes to programming and equipment that utilization geometrical equations to speak to pictures. The other technique for speaking to graphical pictures is through piece maps, in which the picture is made out of an example of specks. This is some of the time called raster designs. Projects that empower you to make and control vector designs are called draw programs, while programs that controlled piece mapped pictures are called paint programs. Vector-arranged pictures are more adaptable than bit maps since they can be resized and extended. What's more, pictures put away as vectors look better ondevices (screens and printers) with higher goals, though bit-mapped pictures consistently show up the equivalent paying little mind to a gadgets goals. Another bit of leeway of vector designs is that portrayals of pictures frequently require less memory than bit-mapped pictures do. Practically totally modern designs frameworks, including CADD frameworks andanimation programming, use vector illustrations. What's more, numerous printers (PostScriptprinters, for instance) use vector illustrations. Textual styles spoke to as vectors are called vector text styles, versatile textual styles, object-situated textual styles, and layout textual styles. Note that most yield gadgets, including speck framework printers, laser printers, and show screens, are raster gadgets (plotters are the outstanding special case). This implies all articles, even vector objects, must be converted into bit maps before being yield. The distinction between vector illustrations and raster designs, in this manner, is that vector illustrations are not converted into bit maps until the last conceivable second, after all sizes and goals have been determined. PostScript printers, for instance, have a raster picture processor (RIP) that plays out the interpretation inside the printer. In their vector structure, along these lines, designs portrayals can conceivably be yield on any gadget, with any goals, and at any size. Raster Graphics In PC designs, a raster illustrations picture, or bitmap, is a dab framework information structure speaking to a generallyrectangular lattice of pixels, or purposes of shading, distinguishable by means of a screen, paper, or other presentation medium. Raster pictures are put away in picture documents with changing configurations A bitmap relates bit-for-bit with a picture showed on a screen, for the most part in a similar arrangement utilized for capacity in the presentations video memory, or possibly as a gadget free bitmap. A bitmap is actually described by the width and stature of the picture in pixels and by the quantity of bits per pixel (a shading profundity, which decides the quantity of hues it can speak to). The printing and prepress businesses know raster designs as contones (from constant tones). The inverse to contones is line work, generally actualized as vector designs in advanced frameworks. What is the contrast among vector and raster designs? Answer: The distinction among vector and raster designs is that raster illustrations are made out of pixels, while vector illustrations are made out of ways. A raster realistic, for example, a gif or jpeg, is a variety of pixels of different hues, which together structure a picture. A vector realistic, for example, a . eps document or Adobe Illustrator? record, is made out of ways, or lines, that are either straight or bended. The information document for a vector picture contains the focuses where the ways start and end, how much the ways bend, and the hues that either fringe or fill the ways. Since vector illustrations are not made of pixels, the pictures can be scaled to be exceptionally enormous without losing quality. Raster illustrations, then again, become blocky, since every pixel increments in size as the picture is made bigger. This is the reason logos and different plans are normally made in vector design the quality will appear to be identical on a business card as it will on an announcement. Vector Graphics regularly are created utilizing drawing or outline programs (e. g. , Adobe Illustrator) and are made out of scientifically characterized geometric shapesâ€lines, items and fills. Since vectors involve both size and bearing, vector components hence are included line portions whose length speaks to greatness and whose direction in space speaks to course. Vector designs as a rule are handily adjusted inside the making application and for the most part are not influenced inconveniently by scaling (expanding or diminishing their size). Since vector components are numerically characterized, scaling basically requires alteration of their scientific areas. Nonetheless, vector records don't bolster photographic symbolism well and regularly can be risky for cross-stage trade. Vector designs normally are spared as EPS group. This makes vector illustrations perfect for logo plan. Making a vector logo is increasingly troublesome however the exertion pays for itself when the vector logo record is sent to printers or sign producers and so on. The vector logo can be scaled up or down with out losing quality and would empower smooth progress between different media. Raster Graphic Images are created by computerized picture catch gadgets: advanced scanners or computerized cameras, or by pixel altering programs (e. g. , Adobe Photoshop). Raster pictures are made out of a framework (network) or bitmap of advanced picture components (pixels). Pixels are squares or square shapes depicted as dark, white, dim or shading. Raster pictures commonly are spared as TIFF group, however can be spared as EPS also. Though transformation from vector to raster is handily practiced, raster change to vector is considerably more troublesome (and regularly is beyond the realm of imagination). Raster pictures normally are effortlessly shared across different stages, yet can be more troublesome than vector illustrations to change. Too, raster designs are affected by scaling. Making a raster logo configuration utilizing Adobe Photoshop may be perfect for web just utilization yet on the off chance that you are not kidding about marking, at that point the subsequent raster PSD logo document will be of restricted use. At the point when sent to a printer or sign creator and when they attempt to scale the raster logo, the quality break down and pixellation happens. Truly, concurred, making the raster logo structure in Photoshop would empower an originator to heap on dazzling impacts, (for example, drop shadows, slanting, obscuring and so forth). Yet, the last deliverable will have constrained employments.

Internet Privacy Essays (652 words) - Privacy, Digital Rights

Web Privacy Web Privacy For what reason would it be a good idea for me to stress over protection and security? I'm not a lawbreaker or a fear based oppressor. I have nothing to cover up. These are things that a great many people think. They likewise accept the web is substantially more secure and that their own data is just accessible to them, while this is quite off-base. There are more motivations to need to ensure your security than can be named. The significant chief is that you have a privilege to protection as long as that privilege is utilized inside the limits of the law. Looking for protection ought not cause you to feel blameworthy. Protection ought to be expected, and requested. The reasons may be as basic as safeguarding your option to communicate disliked sentiments without being exposed to oppression, or on the other hand as genuine as imparting touchy business data, uncovering charge card numbers, legitimate conversations with your bookkeeper, or stowing away your actual personality from a mystery government. Despite your reasons, protection is your right. In spite of what some overseeing bodies may need general society to accept, not each one of those worried about security and protection are programmers or psychological militants. The web gives one of the most straightforward specialized apparatuses ever managed by humanity. It is speedy, advantageous, cheap....and as unreliable as it is snappy, helpful, and modest. A message sent numerous months prior may stay on an ISP's server or as a reinforcement, and can be handily recovered by any individual who realizes how to do as such. This is data which you by and by have erased for an explanation - not to be gotten to by another person after you have gotten done with it. There have been times where data has be recovered as long as a half year after, and utilized in a legal dispute as proof. It tends to be very straightforward for somebody to block your messages or data in the event that they need it. This might be only a director of your ISP or your office organize. Or on the other hand it may be a business contender, lawful enemy, or government office, with significantly more genuine goals. There are an inexhaustible methods accessible to secure online protection. Some are huge and complex while others are amazingly straightforward. The significant truth is that a few strategies are completely ailing in security while others are basically impenetrable. It is a very regular misguided judgment that namelessness rises to security. Secrecy and protection might be connected, however their noteworthiness is very unique. Do you wonder what others think about you? Treats are accessible on specific sites, and these little documents are put on your PC and record information which frequently contains data that the client would prefer to be kept secure. Data including passwords, charge card numbers and where the client has been. There are several electronic email administrations that seem to offer secrecy. Few truly do. These incorporate names such as Hotmail, Yahoo, Excite and a lot more that could be recorded. In each of these cases, the client is permitted to make an individual username that he utilizes for his messages. Tragically, through sign-up techniques and logging, it is incredibly easy to decide your ISP, and even your actual character, at the point when you utilize these administrations. For the undeniable explanation, there is no point in squandering space managing those sorts of administrations. As the client, it is your obligation to realize that your web namelessness is as it were as secure as the administration's protection approach. You ought to consistently acquaint yourself with the use and security arrangements of any E-mail or web administration you think about utilizing. Who needs to realize what you're stating? It may be a nosey individual worker, your boss, your ISP, a rival, companion, or lawful group. Despite who needs to, it is strikingly simple for another person to peruse what you compose. It is sound judgment to secure data that you don't need others to know, and individuals ought to guarantee that they go to certain lengths to do as such. There are countless charitable associations that have practical experience in ensuring your privileges to protection. It is time all around spent to visit these destinations, as you can realize what the present laws are, what is being proposed, and what is being done to ensure security.

Livin la Vida Española (Pt. 1)

Livin’ la Vida Española (Pt. 1) ¡Buenos días! from Spain! While these festivities are going on at MIT proper, I have been in Spain for more than two weeks! I dont know how many students from Spain apply to MIT each year, but just in case someone from Spain is reading this, allow me to say that you have one beautiful country. Recap (for people who are wondering why Im in Europe right now, when there was an amazing Hunt (yes, I know, Im sad too) going on at MIT): 6. Im in Europe because of 21F.782, which is a Spanish II class that is conducted entirely in Spain = living with Spanish host families and speaking Spanish almost 24/7! 28. 21F.782 covers the entire scope of a semester-long language course, which means 3 hours of class every day (from 10 AM to 1 PM) and at least one test every day of class (we cover the equivalent of one week in normal semester schedule every day). 496. Other than the classes, theres plenty of time every day to explore Madrid, venture to other cities during the weekends, and enjoy the delicious European food. 8128. Actually, 21F.782 is definitely not the only IAP language program that exists at MIT. There are plenty of other condensed-semester IAP language courses on campus (German I takes you to Germany)! The coolest thing about an immersion program is that you are completely listening, reading, and seeing the language EVERYWHERE around you. When I took Spanish in high school, it was 50-minutes of class, and then its adiós español until the next class period. Grammar/writing was important, because even if you completely suck at listening or speaking, you can still fake it pretty well in just a language class, since its just for 50 minutes. Here, if you cant speak Spanish, then you just cant speak Spanish on the streets. Gradually, as time passes, you start finding complete sentences rolling off your tongue, and soon, youre starting to make sense of the daily newspaper, the subway announcements, and having 2-hour-long conversations with your Spanish host. Its seriously awesome. :) This had been a really refreshing break from MIT, and I think this is a really cool way to spend IAP, actually (although I am missing my first IAP at MIT). Living in Spain had taught me how to appreciate the little moments of my life, away from the stress and pressure that does sneak up on me during term. Here, life is beautiful. (and warm too!! Its around 80 degrees in Barcelona, where I just came back from. Its like what, 30 degrees in Boston? =p) Now, forgive me for being tourist-y. * Okay, I just realized that Im such a bad student and I didnt actually put up any pictures of us having class. But rest assured, we ARE having class in Spain and its not all just tourism (*guilty grin*)! :) If you want to find out more, youre welcome to read our class blog! Each student in the program is required to write 3 short entries for the blog each week, detailing their travels, as part of the program assignments. Minimum Spanish ability required. Hasta luego! =D

Dual Role Relationships Impacting The World Of Counseling

Dual Role Relationships: Impacting the World of Counseling Anna O Bannon Lindenwood University, Belleville Dual Relationships: Impacting the World of Teaching and Counseling Dual relationships play a big part in the counseling environment. Unfortunately, they transpire without notice but once those lines are crossed, it is ultimately the counselor’s responsibility to ensure proper guidelines are being followed so the client is not being exploited. Guidelines are generally adhered to if the counselor maintains professional distance and recognize the boundaries that are set in place. If the client is exploited, the counselor is faced with the task of fixing the problem and not leaving the client to find his or her way out of this situation. In all likelihood, could result in the patient having a bad experience with counseling, the counselor’s reputation being ruined, or a complaint being filed of which the counselor has to appear before the state licensing board, or in court. The origination of a dual relationships can come about without notice. However, they are very prevalent in the profession of counseling. Pierson and Piazza (1997). p. 89.

An Efficient and Practical Solution to Secure the Passwords of Smartcards Free Essays

AN EFFICIENT AND PRACTICAL SOLUTION TO SECURE THE PASSWORD OF SMARTCARD Abstraction The two peculiar security dangers on acute card-based secret word cheque in conveyed models. Keen card-based secret key verification is a standout amongst the most normally utilised security instruments to concentrate the personality of a distant client, who must keep a significant superb card and the comparison war cry to finish a fruitful confirmation with the server.The proof is by and large coordinated with a cardinal foundation convention and outputs shrewd card-based secret key verified cardinal assention. We will write a custom essay sample on An Efficient and Practical Solution to Secure the Passwords of Smartcards or any similar topic only for you Order Now We utilize two conventions as a portion of this system and they are ( 1 ) enemies with precomputed information put off in the savvy card, and ( 2 ) enemies with typical information ( as for diverse clip infinites ) put away in the astute card. The antagonistic step proposed for the security dangers and secures the conventions. List TERMS- Verification, cardinal trade, disconnected from the net and on-line vocabulary assaults Presentation Distant verification is of amazing significance to guarantee an organized waiter against revengeful distant clients in spread models. To beef up security, crisp card based war cry registry has turned with a title-holder amongst the most extraordinary avowal sections. This methodological analysis includes a waiter and a client and on a regular basis consist three phases. This phase comprise hitch phase, where the waiter issues a acute card to the client. EXISTING System In a current model, A strong and effectual client verification and cardinal assention program using acute cards. It is intended to compel assorted tempting catchs including no secret key tabular array, waiter proof, and so forth. In any instance the important limitation of is a reasonably high computation cost. This is enhanced with another proposition in by mistreating the focal points of pre-computation, i.e. , inordinate operations are finished in the disconnected from the net phase ( before the confirmation ) . It is asserted in that their program can expect logged off word mention assaults irrespective of the fact that the enigma informations put away in a savvy card is traded off. Related Work As a major facet of the security indoors dispersed models, different disposals and assets need insurance from unapproved use. Distant confirmation is the most by and large utilised scheme to concentrate the character of a distant client. This paper examines an orderly attack for formalizing clients by three elements, to be specific secret word, astute card, and biometries. A non specific and unafraid construction is proposed to redesign two-component proof to three-element verification. The alteration non merely wholly enhances the informations verification with easiness to boot secures client protection in disseminated models. Likewise, our system holds a few practice-accommodating belongingss of the basic two-component verification, which we accept is of independent investing. Inculcating false information assault is a singular genuine hazard to remote detector system, for which a enemy studies forge informations to drop conveying on blooper pick at upper degree and verve squander in theodolite hubs. In this paper, we propose a novel transportation velocity proficient helpful proof ( BECAN ) program for dividing infused false information. Taking into history the arbitrary diagram properties of detector hub organisation and the helpful bit-packed proof scheme, the proposed BECAN program can save verve by in front of agenda identifying and dividing the king of beasts ‘s portion of infused false information with minor extra operating expenses at the in theodolite hubs. Furthermore, merely a small part of infused false information demands to be checked by the sink, which accordingly by and large decreases the problem of the sink. Both conjectural and reproduction consequences are given to exhibit the viability of the proposed program every bit far as hig h dividing likeliness and verve sparing. Secret word verification has been embraced as a standout amongst the most by and large utilised agreements as a portion of system environment to screen assets from unapproved access.Recently, Lee–Kim–Yoo [ S.W. Lee, H.S. Kim, K.Y. Yoo, Improvement of Chien et Al. ‘s distant user hallmark strategy utilizing smart cards, Computer Standards A ; Interfaces 27 ( 2 ) ( 2005 ) 181–183 ] and Lee-Chiu [ N.Y. Lee, Y.C. Chiu, Improved remote hallmark strategy with smart card, Computer Standards A ; Interfaces 27 ( 2 ) ( 2005 ) 177–180 ] individually proposed a acute card based secret cardinal proof program. We demonstrate that these two programs are both capable to phony assaults gave that the informations put away in the savvy card is revealed by the enemy. We likewise suggest an enhanced program with formal security verification. Despite the fact that the acute card brings amenitiess, it similarly builds the danger on history of lost cards. When the smart card is possessed by an aggressor, the aggressor will perchance try to analyse the secret information within the smart card to infer the hallmark mechanism of the waiter and so hammer user certificates or interrupt the full hallmark system In this paper, we analyze the lost smart card onslaught from Juang et al.’s strategy [ 5 ] that proposes watchword authenticated cardinal understanding. In order to bolster the security of the full system, we mitigated some of its failings. Computer security is one of most of import issues around the universe. Most computing machine systems are utilizing watchwords for their ain hallmark or confirmation mechanisms. A robust and efficacious attack for categorization of 24 individuals who their typewriting forms were collected introduced. A additive ( LDC ) , quadratic discriminant classifier ( QDC ) and k nearest neighbor ( K-NN ) are utilized to sort users keystroke forms. After that a set of mentioned ensemble methods are adopted to cut down the mistake rate and increase the dependability of biometric hallmark system. Promising consequences have been achieved. The best mean FAR, FRR and EER parametric quantities are achieved for remarkable classifiers as 19.20 % , 0.81 % and 1.39 % severally. The province of the art public presentation consequences mean FAR, FRR and EER parametric quantities are achieved for the ensemble classifiers as 0.00 % , 0.00 % and 1.15 % severally. The comfort of 802.11-based distant entree systems has prompted unbounded organisation in the client, modern and military parts. Notwithstanding, this use is predicated on a verifiable guess of classifiedness and handiness. While the security imperfectnesss in 802.11 ‘s indispensable in private constituents have been by and large promoted, the dangers to system handiness are far less loosely increased in value. Actually, it has been proposed that 802.11 is deeply powerless to noxious disclaimer of-administration ( DoS ) assaults concentrating on its disposal and media entree conventions. This paper gives an explorative scrutiny of such802.11-particular assaults – their common sense, their adequateness and possible low-overhead execution PROPOSED SYSTEM Existing program was farther enhanced by proposed program. which demonstrates that attackers can efficaciously copy the client with old secret key and old information in the savvy card. In this manner, another program was proposed to change that imperfectness, together with a few other new belongingss, for illustration, frontward enigma and secret key altering with no coaction with the waiter. The security scrutiny made in demonstrates that the enhanced program stays procure under disconnected from the net word mention assault in the superb card bad luck instance. A alteration of bing program was as of late presented and Compared with the old program, the new program in gives the convenience of secret key altering operations and has a few attractive key belongingss. Faculties PRODUCT PRESPECTIVE Existing described a efficient user hallmark and cardinal understanding strategy utilizing smart cards. Existing strategy can be viewed as an betterment over the one proposed in, which is designed to suit a figure of desirable characteristics including no watchword tabular array, waiter hallmark, etc. But the major restriction of is a comparatively high calculation cost. This is improved with a new proposal in by working the advantages of pre-computation, i.e. , dearly-won operations are completed in the offline-phase ( before the hallmark ) . It is claimed in that their strategy can forestall offline-dictionary onslaughts even if the secret information stored in a smart card is compromised. PRODUCT FEATURES Existing strategy was farther improved by hearty strategy shows that aggressors can successfully portray the user with old watchword and old informations in the smart card. Therefore, a new strategy was proposed to repair that defect, together with several other new belongingss such as forward secretiveness and watchword altering without any interaction with the waiter. The security analysis made in indicates that the improved strategy remains unafraid under offline-dictionary onslaught in the smart-card loss instance. An betterment strategy was late introduced by hearty strategy. Compared with the old strategy, the new strategy in provides the serviceability of password-changing operations and has several desirable key belongingss. DESIGN AND IMPLEMENTATION CONSTRAINTS Constraints IN ANALYSIS Constraints as Informal Text Constraints as Operational Restrictions Constraints Integrated in Existing Model Concepts Constraints as a Separate Concept Constraints Implied by the Model Structures Constraints IN DESIGN Determination of the Involved Classs Determination of the Involved Objects Determination of the Involved Actions Determination of the Require Clauses Global actions and Constraint Realization Constraints IN IMPLEMENTATION A assorted leveled organizing of dealingss may convey approximately more categories and a more addled construction to put to death. Accordingly it is suiting to alter the assorted leveled connexion construction to an easier construction, for illustration, an established degree one. It is slightly direct to alter the formed assorted leveled theoretical account into a bipartite, degree theoretical account, consisting of categories from one position and degree dealingss on the other. Flat dealingss are favored at the outline degree for grounds of effortlessness and usage easiness. There is no personality or usefulness connected with a flat connexion. A flat connexion compares with the connexion thought of element relationship demonstrating and legion point situated systems. SYSTEM FEATURES This paper returned to the security of two secret key validated cardinal assention conventions using superb cards. While they were thought to be unafraid, we demonstrated that these conventions are faulty under their ain intuitions separately. Specifically, we considered a few kinds of enemies which were non viewed as in their lineations, e.g. , enemies with precomputed information put off in the astute card and enemies with diverse information ( as for typical clip gaps ) put away in the smartcard. These enemies speak to the possible dangers in spread models and are non the same as the usually known 1s, which we accept merit the consideration from both the scholarly universe and the concern. We likewise proposed the replies for fix the security defects. At the terminal of the twenty-four hours, our results highlight the criticality of extended security theoretical accounts and formal security scrutiny on the constellation of secret word verified cardinal assention conventions using superb cards.

Potential Causes of Medication Errors †Free Samples to Students

Question: Discuss about the Potential Causes of Medication Errors. Answer: Introduction A medication error is a preventable event which may occur because of inappropriate use of medication while the medication is under the healthcare professional control. According to Blank (2011), the medication error is the commonly reported error in the emergency department with most of the mistakes happening during the administration phase manegement. The purpose of this study is to identify practices that may improve and reduce the dosage administration errors that occur and may lead to adverse effects on the patient (Flynn, 2012). The study took three months where 75% out of the 127 nurses participated in the research, and the method that got used in the study was educational intervention. On the other hand, the Do not Interrupt approach to medication refers to the interrupts that occur when nurses are administrating medication. The study took eight weeks where 227 nurses participated in the study, and they administered 4781 medications. Therefore, the Back to Basic and Do not Int errupt approaches to medication are directly related because when interruption of the nurse occurs when she is administering medicine, this may lead to a medication error. The purpose of the Back to Basic approach study is to reduce the medication administration errors that occur often in the emergency department. Medication errors can get classified into different categories which include action-based slips, knowledge-based mistakes and memory based lapses. On this study, the Back to Basics' study involved an examination of 95 nurses based on their knowledge on medication administration procedures, the reflection of their behaviors towards recommended medication practices and their medication administration errors. The study was conducted in three months by assessment through tests, surveys and observations on the nurses' chart reviews and voluntary error reports (Blank, 2011). In the Back to Basics approach to medication, the pre-test conducted reported that 69% of the nurses achieved perfect scores while 91% achieved perfect scores in the post-test. In the post-survey, the clinicians in their specific proportions said they followed the recommended p ractice most of the time which increased in 8 of the ten survey questions. The results, however, showed that there was no significant change from the survey conducted (Blank, 2011). Moreover, the review of charts revealed little difference in total medication errors (25% and 24% respectively). It, therefore, means that the nurses scored 299 during the pre-test and 295 during the post-test. During the voluntarily reported medication errors dropped from 1.28 to 0.99 per 1000 patients (blank, 2011). Critique of the Back to Basic Approach to Medication The sample size used for the research was sufficient because majority of the nurses participated in the study where 75% out of 127 nurses participated. The time taken for the study was sufficient because it took 3 months to get the results of the study. Educational intervention got used as the dependent method for the study since it provides nurses with the required knowledge of the medication administration practices. The method of education is however not sufficient in delivering the change necessary in medication administration practices. Hence, the survey and the chart review are classified as the internal validity of the study because they provide the required emphasis that are made by the research management. Furthermore, External validity is the general method that got used for the whole study which is the educational intervention (Blank, 2011). On the other hand, the aim of the Do not Interrupt study was to divert interruptions, educate clinicians and patients and to give reminders regularly and reduce the number of interrupts that happen when nurses are administering medication. This particular study was carried out in a major teaching hospital in Adelaide (Australia) where four random wards were selected to take part in the study while the control wards got blinded in the intervention. Furthermore, the period chosen for the study was two months (8weeks), and the methods used for this approach were administering vests to the clinicians, the general survey of the participating nurses and giving educational lessons to the patient and nurses (Westbrook, 2017). After the elapse of the study period, the Do not Interrupt approach yielded that 227 nurses were administering 4781 medications. The nurses experienced 57 interruptions per 100 medication administrations, whereby 89.7% were unrelated to the task at hand (Westbrook, 2017 ). The four wards experienced a significant reduction in non-medication related interruptions from 50 interruptions per 100 medication administrations to 34 disruptions per 100 medication administrations. Despite the decrease in interruptions, the post-study survey results stated that the intervention ward nurses found the vests to be time consuming and bulky; therefore only 48% seconded the idea becoming hospital policy (Westbrook, 2017). The sample size of the research was sufficient because it comprised of 227 nurses who were able to administer 4781 medications during the eight weeks of the research. Furthermore, the time taken for the research was enough because it took 2 months for the study to get completed. One can identify the internal validity of the study as the use of vests during medication administration, the putting of strategic measures aimed at preventing interruptions and the education of nurses and patients. The external validity of the study was the randomization of four wards that were supposed to be used in the research. The method was however not seen as sufficient because only 48% of the nurses applauded it to become a hospital policy management (Westbrook, 2017). Comparison of the Two Approaches to Medication These two approaches of medication go hand in hand in that through the reduction of the number of interruptions during operations; medical personnel can focus solely on medication administration which eventually reduces the medication errors. According to Blank (2011), the Back to Basics approach improves the nurses knowledge of the recommended medication administration practices. Inadequate knowledge, incomplete information about clinical characteristics and the lack of previous patient records can result in prescribing inappropriate medications. For instance, some infants died to an overdose of heparin drugs due to the wrong labeling of the medicine and the bad packaging of the medicine which resulted to the medication error that caused the death of the infants (Anderson, 2010). Another example is when the clinician prescribes penicillin without having established whether the patient is allergic or not. This means that the Do not Interrupt approach of medication is the most signifi cant compared to the Back to Basic approach because it often happens before the medication error occurs. This means the dosage error must occur for the medication error to happen which is the Back to Basic error. Moreover, the insufficient nurse experience may lead to medication errors where the nurse does not know the required dosage for a specific drug and this may lead to wrong prescriptions that may be fatal to a patient. Therefore, when the nurse has adequate skill and experience in their particular fields such errors may be avoided because the nurse knows the required dosage a patient should take (Karavasiliadou, 2014). Furthermore, the lack of sufficient protocol regarding the arrival time of medicines to the hospital may lead to late medication administration (Karavasiliadou, 2014). Observations made indicate that the rate at which medication errors get reported as voluntary is low (Aronson, 2009). For instance, when a patient was to be given a dosage of a particular medicin e at nine in the morning, and the medication happens to arrive at eleven, it means that the dosage will happen more than two hours past the correct administration time. Though this may not have severe effects on the patient, the patient may still have minor effects due to the delay of their medication. According to Velo (2009), another factor that can lead to clinical issues is the poor legible handwriting by the nurse when prescribing medication to a patient. The nurse can use abbreviations and not write the required dosage information entirely. This shows that the prescription error must occur for the medication error to happen. This is significant in that the Do not Interrupt which is the prescription error often takes place before the Back to Basic approach happens. The Back to Basic approach is often stated as the medication error. From the article, the two approaches of medication have a relative contribution in the clinical issues that often occur because irregularity must ha ppen during medication administration so as for the medication error to occur. Therefore, the Do not Interrupt approach is the most significant approach to medication because it determines whether the medication error (Back to Basic approach) may take place. Hence, it is essential for the nurses to get regular updates regarding the medication errors that occur within their facility so that they have an understanding of the best ways in which they can administer medication. According to Svitlica (2017), it is crucial when the nurses have an understanding of the errors that occur and the importance of reporting them in case they happen. From these two papers, we can conclude that improved education and improved working conditions may help in reducing the risk of medication errors. References Anderson, P., Townsend, T., CCRN-CMC, C.

The Sun Also Rises Essays (2591 words) - English-language Films

The Sun Also Rises The Hemingway Hero Prevalent among many of Ernest Hemingway's novels is the concept popularly known as the Hemingway hero, an ideal character readily accepted by American readers as a man's man. In The Sun Also Rises, four different men are compared and contrasted as they engage in some form of relationship with Lady Brett Ashley, a near-nymphomaniac Englishwoman who indulges in her passion for sex and control. Brett plans to marry her fiancee for superficial reasons, completely ruins one man emotionally and spiritually, separates from another to preserve the idea of their short-lived affair and to avoid self-destruction, and denies and disgraces the only man whom she loves most dearly. All her relationships occur in a period of months, as Brett either accepts or rejects certain values or traits of each man. Brett, as a dynamic and self-controlled woman, and her four love interests help demonstrate Hemingway's standard definition of a man and/or masculinity. Each man Brett has a relationship with in the novel possesses distinct qualities that enable Hemingway to explore what it is to truly be a man. The Hemingway man thus presented is a man of action, of self-discipline and self-reliance, and of strength and courage to confront all weaknesses, fears, failures, and even death. Jake Barnes, as the narrator and supposed hero of the novel, fell in love with Brett some years ago and is still powerfully and uncontrollably in love with her. However, Jake is unfortunately a casualty of the war, having been emasculated in a freak accident. Still adjusting to his impotence at the beginning of the novel, Jake has lost all power and desire to have sex. Because of this, Jake and Brett cannot be lovers and all attempts at a relationship that is sexually fulfilling are simply futile. Brett is a passionate, lustful woman who is driven by the most intimate and loving act two may share, something that Jake just cannot provide her with. Jake's emasculation only puts the two in a grandly ironic situation. Brett is an extremely passionate woman but is denied the first man she feels true love and admiration for. Jake has loved Brett for years and cannot have her because of his inability to have sex. It is obvious that their love is mutual when Jake tries to kiss Brett in their cab ride home: 'You mustn't. You must know. I can't stand it, that's all. Oh darling, please understand!', 'Don't you love me?', 'Love you? I simply turn all to jelly when you touch me' (26, Ch. 4). This scene is indicative of their relationship as Jake and Brett hopelessly desire each other but realize the futility of further endeavors. Together, they have both tried to defy reality, but failed. Jake is frustrated by Brett's reappearance into his life and her confession that she is miserably unhappy. Jake asks Brett to go off with him to the country for bit: 'Couldn't we go off in the country for a while?', 'It wouldn't be any good. I'll go if you like. But I couldn't live quietly in the country. Not with my own true love', 'I know', 'Isn't it rotten? There isn't any use my telling you I love you', 'You know I love you', 'Let's not talk. Talking's all bilge' (55, Ch. 7). Brett declines Jake's pointless attempt at being together. Both Brett and Jake know that any relationship beyond a friendship cannot be pursued. Jake is still adjusting to his impotence while Brett will not sacrifice a sexual relationship for the man she loves. Since Jake can never be Brett's lover, they are forced to create a new relationship for themselves, perhaps one far more dangerous than that of mere lovers - they have become best friends. This presents a great difficulty for Jake, because Brett's presence is both pleasurable and agonizing for him. Brett constantly reminds him of his handicap and thus Jake is challenged as a man in the deepest, most personal sense possible. After the departure of their first meeting, Jake feels miserable: This was Brett, that I had felt like crying about. Then I thought of her walking up the street and of course in a little while I felt like hell again (34, Ch. 4). Lady Brett Ashley serves

Abigail Williams of the Salem Witch Trials

Abigail Williams of the Salem Witch Trials Abigail Williams (estimated to be age 11 or 12 at the time), along with  Elizabeth (Betty) Parris, daughter of Rev. Parris and his wife Elizabeth, were the first two girls in Salem Village to be accused of witchcraft during the infamous ​Salem Witch Trials. They began exhibiting odd behaviors in mid-January of 1692, which were soon identified as being caused by witchcraft by a local doctor (presumably William Griggs) called in by Rev. Parris. Family Background Abigail Williams, who lived in the home of the Rev. Samuel Parris, has often been called a niece or kinfolk of Rev. Parris. At the time, niece may have been a general term for a younger female relative. Who her parents were, and what her relationship was to Rev. Parris, is unknown, but she may have been a household servant. Abigail and Betty were joined by Ann Putnam Jr. (daughter of a neighbor) and Elizabeth Hubbard (a niece of William Griggs who lived in the Griggs home with the doctor and his wife) in their afflictions and, then, in accusations against individuals identified as causing the afflictions. The Rev. Parris called in Rev. John Hale of Beverley and Rev. Nicholas Noyes of Salem, and several neighbors, to observe the behavior of Abigail and the others, and to question Tituba, a household slave. Abigail was a key witness against many of the early accused witches, including the first ones identified, Tituba, Sarah Osborne, and Sarah Good, and later Bridget Bishop, George Burroughs, Sarah Cloyce, Martha Corey, Mary Easty, Rebecca Nurse, Elizabeth Proctor,  John Proctor, John Willard and Mary Witheridge. Abigails and Bettys accusations, especially those on February 26 after the making of a witchs cake  the day before, resulted in the arrest on February 29 of Tituba, Sarah Good, and Sarah Osborne. Thomas Putnam, Ann Putnam Jr.s father, signed the complaints as the girls were minors. On March 19, with the Rev. Deodat Lawson visiting, Abigail accused the respected Rebecca Nurse of trying to force her to sign the devils book. The next day, in the middle of the service at Salem Village Church, Abigail interrupted Rev. Lawson, claiming she saw Martha Coreys spirit separate from her body. Martha Corey was arrested and examined the next day. A warrant for the arrest of  Rebecca Nurse  was issued March 23. On March 29, Abigail Williams and Mercy Lewis accused Elizabeth Proctor of afflicting them through her specter; Abigail claimed to see John Proctors specter as well. Abigail testified that she had seen some 40 witches outside the Parris house in a ritual of drinking blood. She named Elizabeth Proctors specter as being present and named Sarah Good and Sarah Cloyce as being deacons at the ceremony. Of the legal complaints filed, Abigail Williams made 41 of them. She testified in seven of the cases. Her last testimony was June 3, a week before the first execution. Joseph Hutchinson, in trying to discredit her testimony, testified that she had said to him that she could converse with the devil as easily as she could converse with him. Abigail Williams After the Trials After her last testimony in the court records on June 3, 1692, the day that John Willard and Rebecca Nurse were indicted for witchcraft by a grand jury, Abigail Williams disappears from the historical record. Motives Speculation about Abigail Williams motives in testifying usually suggest that she wanted some attention: that as a poor relation with no real prospects in marriage (as she would have no dowry), she gained much more influence and power through her accusations of witchcraft that she would be able to do any other way. Linda R. Caporael suggested in 1976 that fungus-infected rye may have caused ergotism and hallucinations in Abigail Williams and the others. Abigail Williams in The Crucible In Arthur Millers play, The Crucible, Miller depicts Williams as a 17-year-old servant in the Proctor house who tried to save John Proctor even while denouncing her mistress, Elizabeth. At the end of the play, she steals her uncles money (money which the real Rev. Parris probably did not have). Arthur Miller relied on a source that claimed that Abigail Williams became a prostitute after the period of the trials.

Theoretical foundations for collaboration Assignment

Theoretical foundations for collaboration - Assignment Example This way, parents are able to convert the home environment into a place where learning can take place with minimum interruptions. The schools assisting parents to build a positive learning environment at home, helps students to develop respect for the parents, while also gaining positive personal values (Epstein, 1997). It is such positive personal values developed by the students that eventually become essential in school learning, since such students will learn with minimal problems at school. The schools can also partner with parents through offering them child-rearing skills, such as those of understanding child development and also adolescence (Epstein, 1997). When parents are equipped with such skills, they become suitably placed to understand the educational requirements of their children at different stages, thus being able to complement the school efforts. The Hoover-Dempsey and Sandler’s theory of parental involvement offers that parental involvement is essential in the educational life of their children (Hoover-Dempsey & Sandler, 1995). However, this theory offers that the success of inviting parents to involvement in schools will only be achieved, if the schools also establish suitable measures that overcome parental involvement barriers. First, this theory proposes that the schools, in playing the role of overcoming the barriers to parental involvement, must motivate and demonstrate parental-efficacy on the parents, through showing the parents that they are capable of, and can be effective in assisting their children in matters of education (Pullmann, Wiggins & Bruns, 2011). Further, the schools can enhance parental involvement through the creation of parental invitation to participate from others, where the use of tools such as newsletters, school emails, specific teacher and specific student invitations

HumanDocuments - Essay Example The introduction of cotton produced a positive effect which completely changed the highly agricultural population towards becoming a manufacturing community. Significant transformations within the society became notable and the social setting was transformed through the way individuals behave within the society (Guest, 28). Traditionally majority of the population within this region relied on arable farming to produce food for their households and any surplus would be sold. The modern day township of Manchester has become inhabited by highly industrious individuals (Kay, 44) The society within the region was comprised of individuals who upheld and believed in the high moral standards as a way of life (Guest, 26). The settlement of disputes, which rarely occurred was undertaken by clergymen, whose authority was unquestionable (Guest, 26). The harmony which existed within the community surrounding the region had since been lost and the society had become highly permissive (Guest, 27). Social norms were observed by all the members of the society, an aspect which enhanced the peace and tranquillity of the region (Kay, 45). The society could be described as having been highly religious as the observation of religious virtues was considered a mandatory aspect of human livelihood. The dress code of the people could testify to the religious beliefs upheld by the people (Tignor et al., 583). Events occurring in relation to the introduction of cotton resulted in an overall transformation of the society and this caused the people to move away for their beloved s ocial norms to other secular behaviours (Kay, 45; Guest, 27). According to Guest, farmers within the regions were content with their traditional and cultural responsibilities and showed little support for transformations occurring within the society (Guest, 27). Men worked and provided for their families and were heavily dependent on their families for social and

Ethical hacking

Ethical hacking Chapter 1 Introduction Ethical hacking is an emerging tools used by most of the organizations for testing network security. The security risks and vulnerabilities in a network can be recognized with the help of ethical hacking. This research completely concentrates on ethical hacking, problems that may occur while hacking process is in progress and various ethical hacking tools available for organizations. Information is the important source for any organizations while executing business operations. Organizations and government agencies have to adopt ethical hacking tools in order secure important documents and sensitive information (Harold F. Tipton and Micki Krause, 2004). Ethical hacker professionals have to be hired in order to test the networks effectively. Ethical hackers perform security measure on behalf of the organization owners. In order to bring out the ethical hacking efforts perfectly a proper plan must be executed. Ethical hacking has the ability to suggest proper security tools that can avo id attacks on the networks. Hacking tools can be used for email systems, data bases and voice over internet protocol applications in order to make communications securely. Ethical hacking can also be known as penetration testing which can be used for networks, applications and operating systems (Jeff Forristal and Julie Traxler, 2001). Using hacking tools is a best method for identifying the attacks before it effect the entire organization. Ethical hackers are nothing but authorized users for the sensitive information or networks of an organization. Using hacking techniques for handling employees in organization and for solving critical judicial cases is not a crime. An ethical hacker use same tools and actions as performed by normal hacker. The main aspect in ethical hacking is that target permission is essential for performing hacking on the information. Ethical hacking can be used while performing security audits in the organization (Kevin Beaver, 2010). Thus, ethical hacking can help in testing the networks by finding out various vulnerabilities. In ethical hacking, a user will get permission to access the important data. Aims and Objectives Aim To investigate the importance of ethical hacking and its implementation in organizations Objectives Finding the importance of ethical hacking tools Understanding the ethical hacking process Implementing ethical hacking tools in an organization Purpose of Study The main of this research is to recognize ethical hacking tools that can be used in organizations and government agencies. Testing the networks is essential in order to maintain security for the organizational information. The difficulties in networks have to be recognized by the security professional so that they can be solved before effecting the organization operations (James S. Tiller, 2005). This research also focuses on carrying out the ethical hacking tools in a particular organization. The advantages of using ethical hacking in business firms can be evaluated by this study. Ethical hacking tools can be implemented in various fields of applications. Various security professionals can be efficient in ethical hacking tools by undergoing a training process. Another major intension of this research is to identify the importance of ethical hacking professionals in providing security to the networks. (Nina Godbole, 2008). Thus, this research entirely focuses on ethical hacking tools which can be implemented for testing the networks. Research Context This research on ethical hacking can be very useful to many organizations as it can provide clear idea about hacking tools. Security professionals and normal users have to be trained well in order to use hacking tools. The importance of ethical hacking while solving many judicial cases can be identified with the help of this research. Management of an organization can be benefited largely through implementing hacking tools. Hacking tools implementation process can be understood with the help of this research (Ronald L. Krutz and Russell Dean Vines, 2007). Network security or data security engineers in organization will come to know about new ethical hacking methods and techniques that are available in the present market by concentrating on this research. The concepts in this study provide knowledge related to security improvements. Business users can hack the data in order to use it for the purpose of evaluating a correct process. Management has to take precautionary measures while a llowing the professional to hack ethically because data may be misused (Rajat Khare, 2006). Scholars who concerned with information security can take the help of this study for attaining the knowledge on hacking systems. Many organizations are encouraging ethical hacking professionals in order to control their business operations effectively. Email systems, data bases and communication applications can avoid or identify attacks by adopting the hacking tools. Malicious attacks on the information or software can be prevented by implementing this research while using ethical hacking tools. The organizations that concerned with security in networks have to use ethical hacking tools (Greg Meyer and Steven Casco, 2002). Hence from the above discussion it can be understood that, business firms, investigating agencies, government systems and web users can make use of this research to achieve the important information in authorized manner. Chapter 2:Literature Review Ethical Hacking and its importance The word hacking is defined as an illegal use of the others computer system or the network resources. Hacker is the term which is formerly meant for the skillful programmer. This is mostly found in the countries like United States and many other countries. The word hacker refers to the names of the persons who enjoys the work in learning the details of the computer systems and stretch the capabilities from the system (Rajat Khare, 2006). The system of hacking describes the fast improvement in the new programs that make the codes for the providing a better security to the system with more efficiency. The word cracker also belongs to the same field it make use of the hacking skills for the unlawful purposes like email id, intruding into others system. Hacking is of different types such as back door hacking, viruses and worms, Trojan horses, Denial of Services, anarchists, crackers, kiddies and ethical hacking (Kevin Beaver, 2010). In the types of hacking system one of the most common h acking is ethical hacking. This is defined as the services that provides the securities for the customers networks, information assets and identifies the vulnerabilities to maintain the reputation of the corporate sectors before it exploit the company. This type of the hacking system provides the high securities to the customers methodologies and techniques to yield high qualities of infrastructures. The ethical hacking system includes some of the service like: Application Testing War Dialing Network Testing Wireless Security System Hardening Application Testing This is an uncover design or the logic flaws which result in the compromising with the unauthorized accessing of the systems, networks, applications or the information regarding the systems. This application testing is used for investigating and identifying the extent and the criticality of the problems exposure to the thick client (Java) and thin client (web browsers) applications. This application testing includes the services like client-side application testing and web application testings (Joel Scambray, Mike Shema and Caleb Sima, 2006). The client-side application testing is the process of developing the software that is used for the measuring the integrated security into the client software constituents. In this system this testing application is based on the gathering of the information by observer using the reverse engineering system. War Dialing This is one of the services that are provided by ethical hacking. War dialing is a method of dialing a modem number to identify open modem connection that supplies access in a remote way to a network for targeting a particular system (Kimberly Graves, 2007). This word is originated from the day the when the internet has come into the existence in most of the companies. This follows the method of scanning to find the strength of the network connection. The tools of War dialing work on the concept that organizations do not pay attention to dial-in ports like they do towards the firewalls. Network Testing The networking testing services of the ethical hacking provides the information on the exposures of the network, services, and solutions on the convergence, protocols and system devices including the virtual private network technologies. This testing process includes a number of constitutes in external and internal devices. It also analyzes the applications of the voice over Internet protocol within the environment of the organization (Greg Meyer and Steven Casco, 2002). The main goal of the network testing application is to make obvious demonstration of the political effects on its development. By making use of this application into the organization, it provides a complete enlightenment to the work for determining the result in the organization. Wireless Security Wireless security services measures the security in the available architecture to provide a guidelines to ensure the system integrity and accessibility of the resources. The working of wireless security is based on the three phases. In the first phase of the operation it identifies the activeness of the wireless networks (Cyrus Peikari and Seth Fogie, 2003). The team of the ethical hacking demonstrates the exposure to the attackers with the space in the wireless network. In the seconds phase of this system it implements a normal users to evaluate the measures of the security that secures the infrastructures of the organization to control the accessing of the devices. During the third phase the team will try to utilize the discovered threats to gain access on other networks. This provides the security in wireless local area network, virtual private network, intrusion detection system and wireless public key infrastructure. System Hardening The system hardening stresses on the network vicinity. Security is the prime factor that determines the level of integrity of the information and resources used in the computing. Effective deployment of the security controls unauthorized, accidental disruption if resources in information technology (Kevin Beaver and Peter T. Davis, 2005). The system hardening assessment is complemented in three phases. The ethical hacking team will analyze the network to identify the loop holes in security updates and other frequent security defects. Scanning of the remote access devices is done for finding out the vulnerabilities. The configuration vulnerabilities and missing security updates are determined in the initial phase. In the second step the host operating system is examined to determine the services available for remote users and their level of impact. All the TCP/IP services and also the Telnet, FTP, Send-mail, DNS and others are tested (James S. Tiller, 2005). The packet fragmenting and loose source routing are used in an attempt to bypass filtering routers and firewalls. The last phase is complicated as the team uses the information gathered from the first two steps to mine the weaknesses and threats that were identified to gain access to the host system. Before the start of the three steps the boundaries for actions and events are determined. Hence from the above context it can be stated that ethical hacking is a methodology that is used for gathering the information on the hacker. The ethical hacker is the expert who is hired by an organization to solve the problems related to hacking in their network and computer system. Need for Ethical Hacking The process of employing someone to hack ones company is ethical hacking. Ethical hacking is one of the tools that are used to judge the security programs of the organizations. It is also referred as penetrating testing, red teaming, intrusion testing, vulnerability and even security judgments. Each one these has different meanings in different countries. Hacking is also described as new development of the existing programs, software and code. It makes them better and more efficient (James S. Tiller, 2005). Ethical hacker can know the details of computer while hacking and become the security professional. It involves in foot-printing, scanning, tacking all the secured information. Ethical means a philosophy with morality. Hackers hack systems to detect dangerous, unauthorized access and misuse (Shon Harris, Allen Harper, Chris Eagle and Jonathan Ness, 2007). Threat and vulnerability are the two dangers the hacker has to face. The hacking report must be confidential as it should face the organizations security risks. If this goes wrong in any way the organization results in fatal, penalties and loss. For example: computer crime is done by misuse of their hacking skills. The need to hack is for catching the thief. Ethical hacking is the correct method to make your computers work properly (Kevin Beaver, 2010). Ethical hacker needs higher level skills compared to penetration testing. Penetration testing is same as ethical hacking but the hacker uses the penetrating tools and tests the security danger. Ethical hacking is known as White Hat in some of the literature. It tests both the security and protective issues whereas penetrating test mainly leads with the security issues (Asoke K. Talukder and Manish Chaitanya, 2008). Some of the websites and companies offer the training, but they cannot be created they are self-made. Various types of testing need different types of softwares and tools. Game freaks use hacking technology in order to win the game. Hackers will d iscover many ways to hack like trial and error method, operating systems, online and determining the threats. Ethical hacking is done by hackers on behalf of the owners, and in normal hacking they use their skills for personal use (Debra Littlejohn Shinder and Micheal Cross, 2008). Cyber terrorism includes common hacking techniques such like viruses, email bombs and natural disasters. Thus ethical hacking is done by hackers on owners request. Mainly this is seen in corporate companies and organizations. Ethical hacking techniques are used for game cheat codes, hacking accounts and other for good result. Majorly used for fight against cyber terrorism and to take preventive action on hackers Types of ethical hackings Ethical hackers use various methods for breaking the security system in the organizations in the period of cyber attack. Various types of ethical hacks are: Remote Network: This process in especially utilized to recognize the attacks that are causing among the internet. Usually the ethical hacker always tries to identify the default and proxy information in the networks some of then are firewalls, proxy etc. Remote dial up network: Remote dial up network hack identify and try to protest from the attack that is causing among the client modern pool. For finding the open system the organizations will make use of the method called war dialing for the representative dialing. Open system is one of the examples for this type of attacks. Local Network: local network hack is the process which is used to access the illegal information by making use of someone with physical access gaining through the local network. To start on this procedure the ethical hacker should ready to access the local network directly. Stolen Equipment: By making use of the stolen equipment hack it is easy to identify the information of the thefts such as the laptops etc. the information secured by the owner of the laptop can be identified (Kimberly graves, 2007). Information like username, password and the security settings that are in the equipment are encoded by stealing the laptop. Social engineering: A social engineering attack is the process which is used to check the reliability of the organization; this can be done by making use of the telecommunication or face to face communication by collecting the data which can be used in the attacks (Bryan Foss and Merlin Stone, 2002). This method is especially utilized to know the security information that is used in the organizations. Physical Entry: This Physical entry organization is used in the organizations to control the attacks that are obtained through the physical premises (Ronald l. Krutz and russel dean Vines, 2007). By using the physical entire the ethical hacker can increase and can produce virus and other Trojans directly onto the network. Application network: the logic flaws present in the applications may result to the illegal access of the network and even in the application and the information that is provided in the applications. Network testing: In this process it mainly observes the unsafe data that is present in the internal and the external network, not only in the particular network also in the devices and including the virtual private network technologies Wireless network testing: In this process the wireless network reduces the network liability to the attacker by using the radio access to the given wireless network space. Code review: This process will observe the source code which is in the part of the verification system and will recognize the strengths and the weakness of the modules that are in the software. War dialing: it simply identifies the default information that is observed in the modem which is very dangerous to the corporate organizations. Techniques and tools required for ethical hacking Ethical hacker needs to understand how to find the network range and subnet mask of the target system. IP addresses are used to locate, scan and connect the target systems. Ethical hacker also should find out the geographical location of target system. This can be done by tracing the messages that are sent to destination and the tools used are traceroute, Visual route and NeoTrace to identify the route the target (Kimberly Graves, 2007). Ethical hacking should use right tools or else task accomplishment of task effectively is difficult. Many security assessment tools will produce false positive and negative or may they even miss susceptibility to attacks. In case of tests in case of physical security assessments they miss weakness. In order for ethical hacking specific tools have to be used for the task chosen. The easier the ethical hacking will become if many tools are used. The right tool must be used at right place. The characteristics in tools for ethical hacking is it should ha ve sufficient document, detailed reports should be there on the discovered attacks regarding their fixing and explosion, Updates and support. The general tools used for ethical hacking in case to find passwords are cracking tools such as LC4, John the Ripper and pwdump (Bragg, Mark Phodes Ousley and Keith Strassberg, 2004). The general tools like port scanner like SuperScan cannot be used to crack passwords. The Web-assessment tools such as Whisker or WebInspect tools are used for analysis of Web applications in depth. Whereas network analyzer tools such as ethereal cannot give good results. While using the tools for any particular task it is better to get feedback from the simple Google searches such as SecurityFocus.com, SearchSecurity.com and Itsecurity.com will give nice feedback from the other security experts which makes ethical hacking easy and to select the right tool. Some of the commercial, freeware and open source security tools are Nmap (Network Mapper), Etherpeek, Super Scan, QualysGuard, WebInspect and LC4, LANguard Network Security Scanner, Network Stumbler and ToneLoc. The capabilities of many security and hacking tools are often misunderstood, such as SATAN (Security Administrator Tool for Analyzing Networks) and Nmap. The other popular tools used in ethical hacking are Internet scanner, Ethreal, Nessus, Nikto, Kismet and THC-Scan (Kevin Beaver, 2007). Cain and able is a ethical tool used for recovery of windows UNIX problems. This is only password recovery tool handles an enormous variety of tasks. It can recover the password by sniffing the network, cracking the encrypted passwords using Dictionary and Cryptanalysis, recording VoIP conversations, decoding scrambled passwords, revealing the password boxes, uncovering cached passwords and analyzing routing protocols. Ethereal is a fantastic open source tool used as network protocol for UNIX and Windows. It allows examining the data which is present in disk or file and can capture the data. This is also known as Wire shark. It has many powerful features which have very rich display filter language and ability to view the TCP session. Another cracking tool Aircrack is the fastest available cracking tool (John Hyuk Park, Hsiao-Hwa Chen and Mohammed Atiquzzaman, 2009). Thus proper tools and techniques has to be used for better hacking and it will be easier by using more and more tools required. Hacking operating system Linux is the operating system which is most useful software that supports and will be helpful to identify the passwords and uses in detecting interruption there are many software tools are utilized for the hacking and security tools are used for the Linux. The tools which are using in this are not harmful tools this is especially used to protect. John the ripper: John the ripper is nothing but password hacking software technique which is usually used to develop for the UNIX operating system. This the most significant process which is used for password testing as it joins all password crackers into single package and the auto detects password hash types which involves the customizable cracker (Ryan, David R. Mirza Ahmad, 2002). It can be run among the different encrypted password methods which involves various crypt password hash forms where usually found on the different UNIX operating systems that is based on the DES, MD5 etc, Kerberos AFS and windows like XP, 200etc.Generally passwords are placed in the LDAP and other tools. Various types of components are used to expand the capability and for involving the MD4 related password hashes. The other one is the NMAP; Nmap is the used to protect the network. It is especially used to identify the network related services on the computer network by generating the map of the network . Nmap is having the ability to identify the services on the computer network instead of this it never advertises its service detection protocol (James turnbull, 2005). However the Nmap can collect many details regarding the remote computers. This will involve the operating system, and uptimes etc are the software products that are used to execute the service, and are used to involve on the local area networks and also on the dealer of the remote network card. Nmap can be run on the linux. Linux is the most important operating system and the windows are the second most important operating system. The other operating system used is Nessus, this software is used to scan the virus. The main aim of this software is used to identify the virus on the tested system such as; the virus will permit the data on to the network (Mark Carey, Russ Rogers, Paul Criscuolo and mike Petruzzi, 2008). Default passwords are utilized on the network accounts. This software is also called as the external to ol which is used to launch the attack. By making use of the mangled packets rejection of the service among the TCP/IP can be done. Nessus the best software used to scan the virus. Many organizations through out the world are using this software. The check Rootkit is the normal program which helps the administrator to check their system for the known rootkits ( James Turnbull, 2005). This program is the shell script by using the LINUX tools similar to the strings and the grep commands to seek out to carry out the core programs for the signatures with the executed process status command to look for inconsistency. This program alternatively use own commands to run. This tool will permit check rootkit to get confident the commands upon which it depend a bit more. Applications and resources Ethical hacking is nothing but the one which performs the hacks as security tests for their systems. Ethical hacking can be used in many applications in case of web applications which are often beaten down. This generally includes Hypertext Transfer Protocol (HTTP) and Simple Mail Transfer Protocol (SMTP) applications are most frequently attacked because most of the firewalls and other security are things has complete access to these programs from the Internet. Malicious software includes viruses and Trojan horses which take down the system. Spam is a junk e-mail which causes violent and needless disturbance on system and storage space and carry the virus, so ethical hacking helps to reveal such attacks against in computer systems and provides the security of the system. The main application of this is to provide the security on wireless infrastructure which is the main purpose of present business organization (BT, 2008). Ethical hacking has become main stream in organizations which are wishing to test their intellectual and technical courage against the underworld. Ethical hacking plays important role in providing security. Resources are the computer related services that performs the tasks on behalf of user. In Ethical hacking the resources are the core services, objects code etc (James Tiller S, 2005). The ethical hacking has advantages of gaining access to an organizations network and information systems. This provides the security in the area of Information technology called as Infosec. This provides security to the high level attacks such as viruses and traffic trough a firewall. This has been providing the security for various applications which are even bypassing the firewalls, Intrusion-detection systems and antivirus software. This includes hacking specific applications including coverage of e-mails systems, instant messaging and VOIP (voice over IP). The resources i.e. devices, systems, and applications that are generally used while performing the ha cking process are Routers, Firewalls, Network infrastructure as a whole, wireless access points and bridges, web application and database servers, E-mail and file servers, workstations, laptops and tablet PCs, Mobile devices, client and server operating systems, client and server applications (Kevin Beaver, 2007). Ethical hacking tests both the safety and the security issues of the programs (Ashoke Talukder K and Manish Chaitanya, 2008). Hence from the above context it can be stated as the ethical hacking is important in the present scenario as providing security is very important now a day. This is very important in web applications as the hacking can be easily done in this case. Problems Ethical hacking is the backbone of network security. The basic problems with this is trustworthiness of the Ethical hacker because lets take an example if a person has been appointed to do Ethical hacking, to provide security for the bank financial issues if the person is not trust to believe this is not safe as the person only considered as thief. Sometimes the big organizations face any problem like there passwords has been hack, this case hiring professionals is very expensive and the organization need to spend a lot on this (Ethical Hacking, 2009). Ethical hacking is just the security to the problem it is not the ultimate solution to it. Ethical hacking report must be kept confidential because they highlight the organizations security risks and attacks. If this document has been falls into the wrong hand the result would be very disastrous for the organization, the main drawback here is the entire information of the organization will be in hands of wrong person and which leads to the loss of the company (Kimberly Graves, 2007). Ethical hacking generally involves breaking down the computer applications and by collecting specific information from the target the ethical hacker can successful to access the information and can reveal it. This results in that highly sensitive information about the targets security capabilities is collected and maintained far away from the owners control. If this information fall into wrong hands results in real attack on the company and another problem is if the information is leaked to the public or stockholders, the business will be in risk, which results in all types of disasters, including negative character by media, loss of customers and legal consequences (James Tiller S, 2005). Ethical hacking use tools while it performing the activity, if the methods and tools are used incorrectly they cause damage (Dr. Bruce Hartly V, 2003). Hence from the above context it can be stated as Ethical hacking provides security but behind th at it provides the disadvantages like the Ethical hacker should be trusted by the organization or business and in case sometimes highly professionals may cost the organization very much so that company has to provide from the unplanned budget and if it goes into the wrong persons hand the business will be in danger and loss of the organization will takes place. Chapter 3: Research Methodology of Hacking Data types: Data type is defined as the format of a data storage which is used to store different set of values. It tells about which type of data to be stored and where to be stored. Data is stored in computer memory. There are two types of data. They are primary data and secondary data. Both primary and secondary data illustrates the gathering of information and to satisfy the goals of business. Primary data is nothing but it is the data which is collected newly and for the first time. The primary data is original. It is the fresh data and is never gathered before. Secondary data is the data which is collected by others (Norman Blaikie, 2009). The data is collected from newspapers, magazines and journals. Secondary data is gathered before primary data since it is time consuming. Data is gathered newly in case of primary data so it takes much time. Secondary data consumes less time. Primary data is used in ethical hacking since the data gathered in this type of data is very efficient. Ethical h acking is used legally for the official purposes. Since primary data is unique and is not compared with any one, it is used in the process of ethical hacking (Rajat Khare, 2006) Hence from the above context it can be said that data types are useful in the ethical hacking. Case study: According to media and people the word hacking denotes misuse and collapse of computers. They describe it as unfair method of solving the problem. In the view of ethical hackers the word hacking refers to creative. One of the organization namely Amazon, it is not proposed to point out the lesser features but deals with tricks for working the company efficiently. Hackers and developers will create new characteristics for Amazon. They bring out the creative thinking and innovative ideas by their work in company (Paul Bausch, 2003). Mainly the ethical hacking is the good way to improve the existing methods and qualities. Many organizations follow these because one can know the administrative password of employees, can reach the behaviour of them and working performance. Employee performance and his project carryout can be studied through ethical hacking. These hackings look easy for them since they are engaged with the security firms to protect the Amazon fields. Not only in Amazon in e ach and every organization is this steps fol
