Information and Systems Security Essay Example | Topics and Well Written Essays - 750 words

Information and Systems Security - Essay Example But with this ease of information access comes the issue of security. With the increase of information flow, there has been an increase in the number of attacks on information by hackers. Attacks such as Denial of Service (DoS) Attacks, Spoofs, Sniffing, etc. have increased with the increase in the availability of hacking tools which are free of cost. Valuable information is lost in the process. For example, if a customer buys a product of a particular organization through their web-site and a hacker presents himself as the organization and receives the money from the customer, valuable information such as the ID of the customer, his credit card numbers, his passwords are all stolen by the hacker. Therefore such information has to be transferred securely over the Internet. Encryption is the most common way of securing valuable information while transmitting over the Internet (Rahman, 2003). Networks are secured in a different manner. They are secured using tools called "Firewalls". W henever transactions or information between a customer and an organization are being carried out, a particular pattern is followed. Firewalls recognize and allow only these transactions or processes to be carried out and block out all the unrecognized patterns. By implementing Firewalls, most of the attacks from the hackers can be kept out. Securing a network just does not happen. There are many issues to be considered when making policies for network security. The three main issues back in the earlier days were Confidentiality, Integrity and Availability. Due to the advances in the technologies, these issues have been mostly resolved. But in the present day Networks, other issues have appeared. These issues will eventually result in the breaching of confidentiality, integrity and availability thereby defeating the cause of coming up with Network Security policies. Security Factors Confidentiality: Confidentiality is ensuring that sensitive information does not fall into the hands of those who are not authorized to have it (Dhillon, 2001). Confidentiality is also known as secrecy or privacy. Integrity: Integrity means that the information is protected against unauthorized changes that are not detectable to authorized users (Kinkus, nd). Authenticity: Authentication means that the parties involved in communication first prove their identity before communication can begin (Tipton & Krause, 2007). Threats Risk to Data Data is the most crucial asset of a company. Remote Data Backups Inc, a leader in data security mentions the following possible reasons for threats to data (RemoteDataBackups.com, 2007): Hard Drive Failures: Hard drives are mechanical magnetic storage devices that are extremely susceptible to failure. Head crashes, circuit board shorts, electrostatic shocks, power surges, etc. can all lead to immediate crash of the hard drives. Viruses: Dangerous viruses can easily wipe out tones of data in matter of seconds. They are designed to affect nearly all parts of an IT system such as Operating Systems, Applications, Networks and Databases. System Changes: Making any inadvertent changes to an IT system may render the system useless. Power Failure: Power surges, sags and failures can damage hard drives

What aurguments can you make, for and against, the assertion that democracy has made striking progress in the world during the past decade - Essay Example In a democratic system of governance, eligible citizens choose and replace the government via free and fair elections, all citizens enjoy the protection of human rights, there is freedom and rule of law, and citizens participate actively in all national matters. As such, democracy respects human rights, elections, women, and civil society. Democracy contrasts a monarch or an oligarchy.However, there has been an assertion that democracy has made striking progress in the world during the past decade. This paper will draw arguments for and against the progress of democracy in Turkey, Libya, and Egypt. Turkey may assume the definition of a democratic, unitary, and constitutional nation with a huge cultural diversity. It has a parliamentary system of governance and its constitution governs the centralized state. The nation has respect free and fair elections where eligible citizens elect a president for a seven-year term. The nation has universal suffrage for both sexes where all citizens above 18 years of age have the right to vote. Indeed, all citizens can participate in independent political organizations, access information and services, and own private property. In the past decades, Turkey has grown in terms of protection of fundamental rights and freedoms where perpetrators of extrajudicial killings can now face trial. Moreover, the military have taken control of the government for three times but later withdraws to allow for the resumption of democratic governance. (Turkone 1). Additionally, Turkey have shown great respect for the rule of law and the Sacred Law, as well as embracing cultural diversity and respect for the ethnic minority. Notably, previous governments introduced successive phases of limited democracy in preparation for full democracy as they encouraged the rise of civil society. However, the progress of democracy in Turkey has been very challenging as the country faced various controversies (Lewis 1) about individual liberties and freedom of w omen. Indeed, the country’s address on the  Kurdish issue (Turkone 1) contracts democratic ideals and human rights in Turkey faced international condemnation where Turkey violated the most human rights in the Council of Europe. The country had no respect for Kurdish rights, the right to life, women's rights and press freedom, and freedom from torture. The country exercised major crackdowns on press freedoms and arrested many journalists. Moreover, the constitutional problems in Turkey challenge democratic ideals. Notably, Turkey lacks a democratic identity and a democratic tradition but has made significant progress in the last decade. On the other hand, Libya is a parliamentary nation under a temporary Constitutional Declaration and governed by the General National Congress. Libya has depicted total disregard for democracy in the past decade. Indeed, the former president of Libya, Gaddafi rose to power through a military coup and ruled for 40 years. He had no respect for d emocracy as he retained all power, disregarded civil society, had no respect for human rights, and did not allow for active participation in national matters by the Libyans (â€Å"UN† 1). Libya banned all political parties from 1972 and all elections were nonpartisan under law. Indeed, Libyans did not participate in democratic elections for 47 years (â€Å"Foreign and Commonwealth Office† 1). However, the urge for democracy led to the revolution, which removed the Gadhafi government. Indeed, the National Transitional Council introduced multiparty democracy as the face of the revolution. Notably, the NTC declared Libya as a new democracy in 2010 where it promised to guarantee the rule of law, respect for civic and human

M. Butterfly Director's Concept Essay Example | Topics and Well Written Essays - 250 words

M. Butterfly Director's Concept - Essay Example The disillusionment is portrayed as a gravest cause of faulty decisions and motives that lead to multiple consequences. For instance, due to his disillusionment, Gallimard in the movie lost his life, family, legacy, wife, and personal dignity. Looking at the complicated love affair, I see the potential of disillusionment in derailing noble courses. Gallimard already had a stable marriage with children and a reputation to safeguard. However, due to the disillusions of beauty and stereotype, he engages in a parallel and fateful affair with a fellow man. It is uncertain whether at any one time it has been morally upright for men to have affairs outside a legally constituted marriage like in the case of Gallimard. Furthermore, the practice of same sex affairs that is the component of the film is uncommon among many civilizations. Only currently are single sex marriages gaining root in liberal

Fundamental aspects of Program Evaluation and its difference between Essay

Fundamental aspects of Program Evaluation and its difference between pure research - Essay Example offer that view that the major purpose of evaluation is â€Å"to judge the merit or worth of the total program being evaluated, as well as the individual elements of that program." (Billings and Halstead, 2005, p. 543-544). On this basis, they state that the elements comprising program evaluation include weighing and interpreting data that is collected from multiple components of the program and then making judgments about the data that has been collected. When an effective evaluation process is carried out, then the people staffing the evaluation program document the impact that a program has on its participants, as well as the institutions that are participating in the program. According to Patton, program evaluation is the collection of information about the â€Å"activities, characteristics and outcomes of programs†, so that (a) it can form the basis upon which judgments are made about the program (b) the information and measures collected can be used to improve its effectiveness and (c) decisions about the future of the program can also be made (Patton, 1997, p 23). On this basis, it may be seen that program evaluation does not merely involve an assessment of how successfully a program achieves its goals. It also takes into account the manner in which the program is being implemented and the proceses being used to achieve this. Additionally, the program evaluation process must also introduce measures to deal with unexpected consequences and assess the potential long term implications of the program being evaluated (Patton, 1997, p 23). This is a particularly important aspect in program evaluation because the efficacy of a particular program will determine whether or not Government funding for that program will be continued. In the case of educational programs, learning is a critical component of program evaluation and is the main determining factor on how effective the program is. Therefore, the process of program evaluation must also pay close attention to

To remain competitive, mobile-device vendors, developers, and network operators must provide end users with a rich and satisfying experience. Mark eting have a great role in promoting wider and broader concept of IT business. Now we should see what are Apple iPhone and RIM Blackberry Smart Phones and what all concepts and business models have been used by both. Data is mainly collected through secondary sources. Collection of information is called a data. Data is of two types. They are primary data and secondary data. Primary data are those which are collected a fresh and for the first time and thus happen to be original in character. Secondary data are those which have already been collected by someone else and which have already been passed through statistical process. Secondary data may be published or unpublished data .For this particular study secondary data used is "Market led strategic change" of Prof. Nigel F. Piercy, which is used as marketing tool and its concept. Secondary data is used for preparing company profile, and previous reports. Apple iPhone and RIM Blackberry: With all of the millions of iPhones already used by highly satisfied users including many corporate executives Apple has been pushed to add features to the iPhone to make it easier for IT staff to manage and integrate into the existing systems. This will enable iPhone users to gain access to server updates pushed from Exchange as they are updated on the server, rather than requested by the client at regular intervals like a typical email program. "When Apple announced that the iPhone would incorporate Exchange support through ActiveSync, they specifically pointed out some shortcomings of RIM's server-based system." (Kim 2008). Apple also highlighted the thousand of existing web-based applications that already work on the iPhone. One major challenge Apple faces in bumping the iPhone up to 3G is that it will require more battery power to operate and the iPhone already has significantly shorter battery life than comparing with other phones. So the company will need to improve the device's battery life but for the current users frequently need to recharge their battery every day. "Apple has given technology managers their iPhone wish list in full in an effort to make its phone more business friendly. The mission: Lure enough enterprises to the iPhone so Apple can hit its 10 million unit goal by the end of 2008." (Dignan 2008). Apple IPhone is the multimedia mobile phone, which enable internet connectivity with touch screen, virtual keyboard, camera phone and portable media player (ipod) along

The Writing Process Essay Example | Topics and Well Written Essays - 500 words

The Writing Process - Essay Example Thus, the individual’s critical analysis skills are polished as a writer. The more educated and experienced the writer, the more mature, decent, organized, and sensible the writing. Individuals do a variety of forms of writing in their everyday life. As they write more, they learn more. These forms of writing include but are not limited to essays, letters, applications, academic papers, research papers, stories, and dissertations. What an individual writes fundamentally depends upon what motivates him/her to write. The motivation behind writing poetry may be hobby. Motivation behind writing a letter or an application may be an urgent need. Motivation behind writing an essay may be passing the exam. Likewise, stories are often written to be published in the newspapers or magazines as this happens to be a source of income for some writers. Different people like and dislike different things about writing, though certain things can be commonly included in either of the two categories. Things that people like about writing is that they can own a thing that they produced in a very short span of time, writing provides people with a way to express themselves freely, and writing saves memories one has at a particular point in time. The ability of writing to express thoughts makes it a form of art. Writing often gets boring when it is imposed upon an individual as a compulsory task. The mere fact that they have to write rather than they can opt to write makes writing essays difficult and boring for the students when they are given this task as a homework. Some things that people commonly dislike about writing is that it can be very biased and manipulative, and that the type of language used in the writing has to be adjusted according to the genre of the writing; language used in an official document is very different from tha t used in poetry. There are certain rules and principles that have to be respected and followed while writing

Lord God forgive me! Essay Example for Free

Lord God forgive me! Essay The grenade had been thrown and it goes through its stages building up to the horror of the war. (Swish swish swish BANG)! This quote shows that there is silence at first and Sherriff shows what the grenade would do. He shows the tense of the atmosphere for example the type of smooth faint noise the grenade would make when it is in the air and then it builds up to the great noise when the grenade lands on the ground. This quote shows the tense of the atmosphere and the stages it goes through until it seems completely realistic. Sherriff uses the this example in the stage direction to show the horrors of war through the atmosphere, through noises he is able to show the violence there is in the war, this quote can help the director create the scene and help the audience give a better understanding of the horrors of war. R. C Sherriff uses a variety of different structures of language through the characters, he shows the audience on how the soldiers had spoken most of the time through out the war and how they might speak due to their class. For example, upper class soldiers would speak in a more posh accent and have a better use of grammar whereas the lower class soldiers would use army jargon such as minnies and pineapples as well as slang such as characters dropping the letters in some words, for example a soldier says e instead of he. Sherriff had created characters with this characteristic on language so he could show the rank the men are in. Osborne is from an upper class therefore he uses language in a good sense of grammar and he speaks words in a posh accent. Osborne: Cheerio. This quote shows that a character called Osborne is from an upper class since he uses words like Cheerio which is a posh word. Mason a cook who constantly speaks slang shows his characteristics to be from a lower class since he uses that sort of language and has a poor level of work in the war. Mason: E said the leopard cant change its spots. This quote shows that a character called Mason is from the lower class since he speaks slang, for example he drops his h when saying he. Sherriff had initially done this because this reflects the rank the men are from so it can give a clear understanding of the characteristics to the audience. The characters Raleigh and Stanhope are significant roles in the play. Raleigh holds the characteristics of a nai ve, inexperienced and gormless person who had just joined the company. Stanhope, who is more opposite to Raleigh, he runs the company which shows that he is much more experienced. Raliegh had known Stanhope from school even though Stanhope was three years older than Raleigh. The characters mainly represent the horrors of war by talking about violence in their conversations and actually going through the process of it when coming to the points of attacking and fighting. Through out the course of the play the characters interact with each other dramatically and emotionally. Their behaviour reflects how they had survived the war, for example they would try not to talk about bad and emotional events and they would try to adapt to positive points while drinking rum. Stanhope talks about upcoming violent events. Stanhope: We must expect this attack on Thursday morning. This quote shows how the characters would represent the horrors of war by talking about an attack which hold the structures of violence, it makes the audience imagine a fight of some sort and injuries which reflect the horrors of war. When the soldiers were to attend an attack six soldiers went but five came back and one had died which was Osborne. Stanhope: Four men and Raleigh came back sir. Colonel: Im very sorry. Poor Osborne. This quote shows that one of the soldiers had died which shows death as a part of the horrors of war and the men interact kindly with each other at this point because their fellow friend had just died. There are many ways the Stanhope and Raleigh had interacted with each other through out the play. At first points of the play Raleigh was more of the shy person and had seemed more scared to talk to Stanhope. Stanhope: How did you get here? Raleigh: I was told to report to your company, Stanhope. This quote shows how Raleigh had reacted in a more respectable manner and had called him Stanhope instead of his original name, Dennis. In addition this quote shows that Raleigh had deliberately joined Stanhopes company which shows that he cares for Stanhope. The play shows how the soldiers were able to cope with the horrors of war since Stanhope had come back from an attack and he had started to celebrate with the other soldiers as soon as he gets back. Mason: I thought I might tell you sir, this is the last bottle. Stanhope: The last bottle! Why damn it, we brought six. Mason: I know sir, but five of them have gone. This quote shows that even after Osbornes death, the soldiers are not that emotional because they face their problems to alcohol and try not to remember those emotional and heartbreaking moments. This quote shows the behaviour the soldiers had that would help them to cope with the horrors of war. Overall this play shows the horrific effects of war and that it puts a bad example on a person, and soldiers are not treated fairly due to their personal problems. In my opinion I think that there is no reason for war, it does nothing other than create a bigger stage of conflict. It ruins many soldiers life, when they could have had a ordinary life but war can put immediate effect on it. Overall I think that R. C Sherriff had tried to outline the horrors of war, the causes of it and how it can also cause soldiers to suffer.
