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

Ethics and Leadership in Engineering

Engineers play a significant part in the development, prosperity and safety of people around the globe. The primary role of engineers is to identify/sense and respond to a need by constructing or creating a solution with certain specific guidelines. While it is the responsibility of engineers to develop such structures, it is also their responsibility that their creation serves the function in a proper manner, take all safety precautions while making it and give the safety directions to the users after handing it over. Discussion These structures, however, do not stay safe forever. No matter how safe a construction or a creation is, it reveals its failure after sometime. Eventually these failures lead to dire consequences some time. Engineers struggle all the time to avoid failures and make their solution safer and more efficient. Sometime mere lacking of professional ethics is the reason. In UK, the seriousness of ethical issues, which arise in professional lives of engineers, has been recognized recently. However, in USA this has been recognized for some time. Their universities offer substantial guidance and support to their professionals. The Royal Academy of Engineering, in 2005, initiated the process and brought its publishing in the form of â€Å"Statement of Ethical Principles†, which outlines the specific ways in which engineers across UK are committed to upholding certain ethical values. During the same time, UK Engineering Council amended its standards for chartered and incorporated engineers, in order to increase awareness of ethical issues. It appears that this has resulted in having a profound effect as many universities have incorporated ethical perspective in their studies. Professional Engineers strive to develop solutions that improve the health and safety conditions for the welfare of society. The statement of Ethical Principles sets standards for professional Engineers (Statement of Ethical Principles. 2005). It presents four principles that guide engineers in their professional duties. It includes Accuracy and Rigour, Honesty and Integrity, Respect for life, Law and the Public Good, and Responsible Leadership. Accuracy and Rigour means, Engineers have the responsibility to acquire and sustain the information relevant to their practices; they should also keep their knowledge up to date. It is also the responsibility to always act with care as their profession requires a strong commitment. They should only perform their services in the field of relevant competence. Since the technical knowledge, an Engineer can understand are not easy for the others, therefore, it is the duty of engineers to not knowingly mislead others as it can have dire consequences and therefore unethical. Honesty and Integrity means; engineers should act with high standards of professional ethics. They should not accept any bribery or questionable payment from anyone. They should act in the best interest of employer, unless it is not in conflict with rights of the other party. Respect for Life, Law and the Public Good, entails that engineers should be aware of relevant laws and regulations and should work accordingly. Conservation of nature and its resources should be a priority. They should act in the best manner that does not bring bad image to their profession. Responsible Leadership involves practicing high level of standards and leadership in the management of technology. Provide awareness to the public. Listen to the concern of the society. Adhering to these principles will bring good name to the profession and will make sure that it achieves what it is meant to be, welfare of society. However, we can have numerous examples from the past, of such negligence and improper conduct in this respected profession. In past successive accidents of railway occurred in UK, which were later fully investigated. These include the accident of Clapham Junction rail crash, on 12 December 1988. 35 people killed while 100 injured, when oncoming train ran into wreckage. Another on, 19 September 1997, Southall rail crash, killed 6 people and 150 injured. It occurred because of a collision with freight train. On 5 October 1999, Ladbroke Grove rail crash happened, when train passed the signal at danger and resulted in the head on collision, killed 21 while 523 injured. Investigation reports show that these could have been prevented by timely action of professional engineers. In America, a TV Antenna Tower collapsed in 1982, killing several people. Later investigation showed that safety measures were not taken as should have been (Uff, 2012, Pp13). Conclusion Engineering is a much respected profession. This respect demands responsibility. Adhering to rules but there arise ethical responsibilities too. However, if professional engineers stick to the four principles and apply them in their activities, it will surely add more value to this profession for sure. Running Head: leadership techniques Managers do things right, while leaders do the right thing. [Name of writer] [Name of institution] Managers do things right, while leaders do the right thing Thesis Statement â€Å"Managers do things right, while leaders do the right thing†. Introduction â€Å"Leaders create and change cultures, while managers and administrators live within them.† (Edward Schein) Managers do things right, while leaders do the right thing. Leader also sounds similar to the manager to the common man. But we know there are subtle differences. It takes a totally different approach to become a leader. These subtle differences create the difference that is visible in performances of organizations. There have been many theories on leadership and management. Talking about whether a manager is born or developed, what styles are of management exist and which is appropriate. Also, what a leader does, where his/her power comes from. First of all we will differentiate between a leader and a manager. Then we will discuss some models and theories related to it. Discussion The role of a manager is to achieve goals effectively and efficiently, by planning, organizing, co-ordinating and controlling. The importance of time is immense. On the other hand, leaders create and communicate a vision, then energise their followers towards achieving that vision. Leaders create a culture of shared values, beliefs and rituals to challenge the status quo. Managers use position authority to make subordinates work towards goals. While leaders motivate and inspire their followers to achieve their goals. Today the trait theory (born leaders) is criticized more. It is argued that even leadership has different styles, which are learned with experience rather than born traits (Daft, 2003, Pp.518). Ashridge Management College did research and found four major classifications of management styles. Tells, sells, consults, join. In tell style, the manager is autocratic, making a decision and imposing it on others. In sell style, manager still makes a decision on self like basis, but try to explain the logic behind it. In consult style, manager makes decision but in consultation with his/her subordinates. The most democratic style is join style, where manager himself becomes part of the team that makes joint decisions, and also claims the responsibility of that decision afterwards. Research indicates managers are generally thought to be having told or sell style. While employees prefer consult style. Choosing which style is more appropriate, depends on several factors. Contingency approach by Charles Handy suggests that four factors need to be understood to answer this question. The environment, task or people, trust or control, liking or respect (Schermerhorn 2012, Pp.266). Each particular combination of these factors results in a different situation and, therefore, requires a different tailored approach of management towards it (Robbins & Judge, 2010, Pp.393). Michigan and Harvard identified two basic types of leaders. Task oriented and people or relation oriented leaders. Both have their own advantages and disadvantages. Ohio state research suggests that task orientation and people orientation can be achieved simultaneously; they are not mutually exclusive. Blake’s management grid proves this research by suggesting rather than asking a question that a manager should be task or people oriented; ask to what extent a manager should be task and people oriented (Daft, 2003, Pp.522). Managers and leaders differ in their approaches towards performing similar tasks. The approach of management is routine in nature. They like to work under conditions of certainty, strive to gain as much information as they gain, take relatively less risk. Leaders on the hand challenge the status quo. They talk about changing the culture and create followers with their motivation and persuasions skills. Leaders create a shared culture towards achieving the vision that followers own. Conclusion Who is best, a leader or manager is, however, a question depending on what needs to be accomplished. If it is a routine or not so dynamic environment, then decision tilts in favour towards manager. While if it involves dealing with changing and fluctuating situation with lots of risk involved then it will require the initiative approach of a leader.

Management of Marketable Securities Essay

Cash and marketable securities are normally treated as one item in any analysis of current assets and holding cash in excess of immediate requirement means that the firm is missing out an opportunity income. Excess cash thus is normally invested in marketable securities, which serves two purposes namely providing liquidity and also earning a return. Investing surplus cash in marketable securities is normally a part of overall cash management. The task of financial managers, who become involved with marketable securities either full time or part time consists of three issues. Initially the managers must understand the detailed characteristics of different short term investment opportunities. Secondly, managers must understand the markets in which those investment opportunities are taught and sold. Finally managers must develop a strategy for deciding when to buy and sell marketable securities, which securities to hold, and how much to buy or sell in each transaction. Need for investment in securities: Marketable securities result from investment decisions that really are not the main part of the firm’s business; however, marketable securities cannot be ignored, as they constitute a part of the value of the firm that is entrusted to management. However, they cannot use the short term surplus cash flows for any long term purposes. Surplus cash is thus invested in marketable securities primarily to earn an income, which otherwise remains idle within the firm. Companies which were flushed with money at one point of time and investing heavily in marketable securities, may issue short term securities to other and borrow money at another point of time. Another prominent reason for holding marketable securities is on account of mismatch between the borrowing and investment programs. Types of marketable securities: Marketable securities available for investments can be grouped under several ways and they can be classified under three broad heads namely debt securities, equity securities and contingent claim securities which in turn can be grouped under several heads. Debt securities: There are different kinds of debt securities namely money market instruments and capital market debt instruments. Money market instruments can be called as call money, certificates of deposit, commercial paper, banker acceptances, government securities or securities guaranteed by the government. Capital market debt instruments can be further subdivided into treasury notes and treasury bonds, Public sector undertaking bonds, corporate bonds etc. Students in order to get good grades in their examinations have to listen the lectures delivered by the teachers and professors keenly; they should allot certain number of hours for home preparation and in case of need they can get home tuition and by clicking the educational websites, they can also learn the topics by help available through finance homework.
