Network Security Term Paper Example | Topics and Well Written Essays - 1750 words

Network Security - Term Paper Example The rapid growth of networking has also come with its own challenges, mainly in the area of network security. Maiwald defines security as the â€Å"freedom from danger, fear or anxiety: safety† (4). He also defines a network as an interlinked system. Therefore, network security can be defined as the safety of interlinked systems. There are to kinds of networks: synchronous network and data networks. Synchronous network systems are made up of switches, which makes them immune to malicious attacks. However, data network systems contain routers that are computer based, making them susceptible to all kinds of malicious attacks. The internet is perhaps the best known and most widely used data network on the globe today. A few years ago, the computer system was seen as a harmless piece of technology and not many people cared really for computer security. To many people at the time, most computer operations and software were illogical, thus the risk of hackers was quite low (Kaufman, Radia and Speciner 43). However, since the mid 1980s, networked computer workstations became common and with this came the issue of information and network security. More and more people are able to read and understand computer algorithms, meaning that the likelihood of a system being hacked into is very easy. Organizations are forced to share networks with distrustful organizations and individuals. The world of network security is quite hostile since a small percentage of the population can cause untold damage to a global network. This is the situation that makes network security such an important matter in today’s highly networked society. There is need to protect the data and information that companies, institutions and individuals need protected by designing fool-proof network security systems. History of Network Security Widespread interest in network security gained ground in the 1980s when Kevin Mitnick hacked into the systems of several companies and made away with $80 million. This was the biggest computer-related crime by a single person in the history of the United States. The birth of the internet also marked the beginning of the interest in network security. In 1969, internet was developed after the Advanced Research Projects Agency Network (ARPANet) was given the mandate to carry out research in networking. ARPANet was an instant success and before long, email applications had become quite popular (Pardoe and Snyder 223). Th InterNetworking Working Group (IWG) was given the responsibility of governing ARPANet by setting the standards for use. On the 1980s, TCP/IP, which is a common langu age shared by all computers connected to the internet, was developed. Thus internet was officially born. The mid 1980s saw a boom in the number of personal and commercial computers which led to many companies joining the internet bandwagon. In the early 1990s it was the urn of the public to get access to the internet, and this marked the birth of the World Wide Web (WWW) era. Today the internet is widespread all across the world and many people carry out their daily activities online (Maiwald 60). The actual history of internet security began in 1918 when an enigma machine that could convert plain text to encrypted messages was developed in Poland. 22 years later, Alan Turing broke the enigma code. The word hacker was first coined by students at the Massachusetts Institute of Technology (MIT). The Telnet Protocol developed in the 1970s and this led to data networks being accessed by the public. The 1980s saw the rise of hackers and computer-related crimes. The Computer fraud and Abu se Act was enacted in 1986 to minimize cases of information stealing from military and federal offices (Kaufman, Radia and

Legal Systems and Contract Law - resit Essay Example | Topics and Well Written Essays - 3500 words

Legal Systems and Contract Law - resit - Essay Example 4. The position of Constance in the existing circumstances and its impact on Calum. 5. Possible remedies available to Calum RULES In order to conduct a critical analysis of the case at hand, it is necessary to examine the relevant components of the English and the Scottish legal systems that differ. However, to set the discussion rolling, it is necessary to examine the general rules that define the concepts of offer, acceptance and contracts in both jurisdictions. English Common Law In order to form a valid contract, there must be an offer and an acceptance. In the general sense, an acceptance must match the terms of the offer and it. The specific method of acceptance must comply with the required method of acceptance1. Thus, if the offeror specifies that an offer must be accepted via one medium of communication, that medium must be used to accept the offer. In other cases, an equally appropriate method of communication of acceptance to the offeror might be sufficient to create a val id contract2. There is a general issue with acceptance of contract offers by post. This is because when a person accepts an offer via post, the offeror might not be aware. Some issues came up in relation to this trend of affairs and hence, a number of significant rulings came up which defined the postal rule in contract law. The postal rule states that an acceptance is effective the moment an offeree posts a document asserting his acceptance3. A lost letter or a delayed letter does not affect the validity of the acceptance4. However, in modern times, the postal rule applies where postal acceptance is specified as the means of accepting an offer5. Offer In the famous case of Routledge V Grant, it was accepted that an offer is valid until there is a revocation. In the case at hand, an offer was made by Grant to lease his premises to Routledge and he stated that he would keep the offer opened for 6 weeks. However, in the third week, Grant revoked the offer and sold it to another person . It was held that there was no contract between them and Grant could revoke the contract at any time and sell it to anyone he pleased6. This is the general law, however there are some modifications under Scottish Law in this. However, in Byrne V Van Tienhoven, it was established that revocation must be communicated to the offeree7. How an Offer May End It is a general position in English law that request for further details does not mean a rejection of the offer8. However, the lapse of reasonable time or specified time of the offer can render it invalid9. Also, failure to meet a given condition of the offer can render it terminated and the offer will not be available anymore10. A counter offer renders an offer invalid, however, in the case of Butler Machine Tools V Ex-Cello11, the House of Lords held that a counter offer creates some kind of bargaining which they called a â€Å"battle of forms† in which the â€Å"last shot wins†. Scottish Civil Law The relevant aspect of the Scottish civil law that is relevant in the law of contract relate mainly to promises, counter offers and remedies. They are discussed below. Promise A promise seeks to invoke a moral rule that obliges the promiser to keep his word. In most jurisdictions including English law, a promise invokes nothing more than a mere moral obligation which is not enforceable in court. However, promises

Humanitarian has tried hard to get full rights for women. The Equal Opportunities Commission once said â€Å"if we get it right for women, well get it right for everyone" (Houston, 2006). Since 1997, efforts have made important progress in undertaking poverty and unfairness and in breaking down the barriers that put off people from fulfilling their potential. Efforts have been made to tackle prejudice and exclusion in every segment of our society This issue of even-handedness to women on which the Fabians Society, the Parliamentary Labour Party, and so many of the people in this room have battled so effectively for years, new deal is the part of their efforts (Houston, 2006). New deal was introduced in Great Britain in 1998. The aim of the program is welfare of society. All of the policies mentioned are for welfare reform. Multiple programs have been introduced: new deal for young, 50+, unemployed musicians, 25+, lone parents and for disabled. The approximate probability changes were slightly higher for women being unemployed  ensuing in a joblessness reduction of around 10-11 thousand and six months after the pseudo New Deal entry date. Though, as for men this reduction fell with a longer follow up time, so that 12 months after the pseudo New Deal entry date, there were 8,000 fewer unwaged young women than if there had been no NDYP. At 18 months from the New Deal entry date there were 5,000 fewer unwaged young women than if NDYP had not been introduced (Wilkinson, 2003). It is much harder to measure succeeding redundancy for unemployment spells that occur normally at the end of the proceedings period. The results show that for men, there is a 0.06 increase in the probability of exiting
