"Computer security and the protection of data has been an issue since the early 1980s when computers became standard office equipment. Company sensitive information is stored on computers. Protecting the access to and integrity of this information has been a key concern for managers and computer specialists alike. The issues in data security have not changed, however the advent of the Internet has made keeping data secure more difficult. The Internet did not change the key issues, just the number of users trying to access the information. Network administrators have been facing these issues for quite some time."

Abstract
This paper discusses the various advantages of outsourcing computer network security in an organization. It explains that companies outsource their network security in order to save money by obtaining the best security measures for the smallest amount of money. Secondly, companies to which security is outsourced specialize in the latest security measures and are, thus, able to provide the best security solutions. Finally, within a company, several political issues may influence the quality of security measures installed. Outsourcing security would eliminate the influence of battles within a corporation.

From the Paper
"Because it is possible to connect to any computer in the world with increasing ease, it is also possible to threaten the security of these connections with increasing ease. Thus it makes sense to implement the best systems. This can be done only if the latest expertise is used. Of course computer knowledge increases rapidly every day. It is only when focusing on a specific aspect that an expert can hope to stay ahead of the increase of this vast body of knowledge. Thus, outsourcing allows specialized service from a company focusing solely on the aspect of network security, while computer experts within a company can focus their efforts towards other duties within the company itself."

Abstract
This paper addresses the importance of having a written and enforceable Computer Network Security Policy for 'The Financial Group', an accounting corporation. The paper shows that the company's accounting systems comprise three major elements: A web-based front-end server, a back-end database, and business-logic applications. OS-level console access is used for system administration. Accountants access the system with Web browsers using HTTP only and are authenticated via the HTTP basic authentication mechanism.

"Passwords are a critical element in protecting the company infrastructure. Remember, the security policy is only as good as the weakest link. If users have weak passwords then the company is at a higher risk for compromise not only by external threats, but also from insiders. If a password is compromised through social engineering or password cracking techniques, an intruder now has access to the company's resources. The result is the loss of confidentiality and possibly the integrity of the company's data as well."

Abstract
The paper explores IKON, a clothing store that has 227 unique locations as of 2002, and that generated $650 million in sales during that period. The paper relates that the store decided to expand its online sales channel and in so doing exposed itself to the online data security risks that all online retailers and online service providers are exposed to. The paper discusses how enterprise network security and related security policies are absolutely crucial to keep corporate data and intelligence safe from unwanted intruders as well as customer data safe from hackers, as in the case of IKON. The paper highlights how when deploying large scale enterprise networks in a big organization like IKON, computer network security has become one of the key areas to be focused upon.

Abstract
This paper examines the issues surrounding computer network security, exploring the ways in which a business computer system can be protected from breaches that occur without permission of the owner of that system. The paper explains that many breaches are either simply for the technical challenge of doing so or because a "hacker" wishes to gain information from that system or to disrupt the work being done by that system. While some hacking is relatively harmless in intent, a great deal of it is highly destructive, or even potentially disastrous. At the highest levels " hacking into the nation's defense system, for example " hacking could be catastrophic. The writer shows that there are a number of ways in which computers can be protected. This paper examines examples of breaches, and of critical safeguards that have proven effective or so promise while in development.

"Hacking " and other computer crimes related to uninvited intrusion " have become a part of both our daily lives and a part of our popular culture. While in the former it is often extremely harmful, in the latter it is often depicted either as good clean fun or as part of the arsenal of those fighting the so-called good fight. This paper examines the ways in which a computer network can be kept secure through the use of a number of both high tech and very low-tech strategies. After defining the problem and looking at the background of this issue, this paper looks at a real-world example of hacking ". and the price that is paid and, in addition, the strategies needed to avoid the pitfalls of intrusive access and attacks on network systems."

Abstract
This paper explains that networking is the process of moving information via computers rather than via any other medium such as paper media or face-to-face communication. The author stresses that, as in the case with larger networks, there are security risks associated with home networks, especially with "always on" broadband Internet services, such as DSL and cable modems. The paper states that, although most people do not think of the Internet as a network, the largest and most global network is the Internet. It is the most wide-reaching and revolutionary type of network that exists today.

"A home network essentially allows individuals to link together all of the computers in their home. A home network can allow a family to save money on multiple peripherals such as printers and fax machines and allow the family to access all of the computers and software stored within the computers linked in the household. In addition, "one of the most compelling reasons to set up a home network is that everyone can be on the Internet at the same time.""

From the Paper
"With the advent of the Internet and Computer Networking programs, the development and amelioration of IT security is the undoubtedly becoming the fastest growing and most solicited segment of the Computer Science industry. The need for protecting computer systems from both internal and external attacks is paramount for any company which utilizes computers as part of their business function. Regrettably, at this time there is no single product, software, hardware or programming that can completely secure any and all systems. Thus every avenue must be explored in an effort to structure as secure of an environment as possible for a computer system. In order to adequately configure this security, a complete analysis of the computer system including hardware, software, and peripherals as well as information on all users and their functions must be completed."

Abstract
This paper discusses computer viruses, computer software programs that interfere with the smooth running of a computer's OS and hardware and are designed to replicate and hide themselves to avoid detection. A virus' main goal is to infect and replicate on as many other systems as possible causing as much damage in the process such as erasing hard disks or deleting vital files that run certain software programs. It presents information that gives users who do not have much experience in this area of network security an introductory overview of what malicious software is and how it works. It examines three main areas of importance, the definition of a virus, types of viruses and virus protection. Trojans and Worms are also covered.

From the Paper
"Viruses are programs and must be executed to become activated. This is done by double clicking on the email attachment or the setup .exe or .com executables for software programs. In one instance as of late the author has seen the W32.Funlove virus spread through a downloaded screensaver for his favorite college football team. The virus was hidden behind the executable and activated when the screen saver was installed. Viruses, in an infected executable file, modifies the original program to point to the virus code and launch that code along with its own. Most of the time the process is to jump to the virus code first, execute it, then go back to the original code."
