Abstract This paper discusses networksecurity and the threat posed by a company's internal employees to networksecurity. The paper explains that while it is recognized that external threats such as hackers, worms, viruses and various email attack strategies pose a significant and often expenses security risk, protecting against these risks is a known quantity. On the other hand, the paper relates that protecting against employee networksecurity risks is more problematic and often requires human resource initiatives in tandem with networksecurity applications and protocols.
From the Paper "There are essentially two separate schools of thought regarding the character of network security vis-a-vis the threat to security posed by employees. On the one hand there is the opinion that employees pose the greatest threat to network security due to their network access and often unrestrained Internet use. Conversely, there is the school of thought that, while admitting that employees pose a considerable security risk, believe that external threats such as hackers and viruses pose a far greater risk. The industry consensus seems to be that both issues need to be addressed but that employee security risks is perhaps the most difficult to prevent since 84% of security violations across a network occur when employees, either intentionally or inadvertently, send proprietary data outside of a company's network."
Abstract This paper explains that networksecurity is importance to organizations particularly in light of e-commerce. The author reviews the role that e-commerce plays in today's companies. The paper highlights electronic commerce and business strategies.
Abstract A paper on pressing securityproblems facing the United States in the coming decade. The problems raised include: China and Russia are great power rivals; weapons of mass destruction getting into the wrong hands are a big threat; civil and ethnic warfare along with terrorism.
Abstract This paper discusses the various advantages of outsourcing computer networksecurity in an organization. It explains that companies outsource their networksecurity 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 securitysolutions. 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 examines the issues surrounding computer networksecurity, 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.

From the Paper "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 Voice over IP (VOIP) is one of the most important emerging trends in telecommunications because it integrates communication services into the IP network infrastructure, the Internet, especially e-mail and instant messaging, and standard classical services like telephony. The author stresses that VoIP has problems of confidentiality, integrity and availability of the data and information, which streams through the network. The paper presents a chapter outline of a thesis, which will discuss implementation of VoIP networksecurity emphasizing maintaining the efficiency of this system.

Chapter One - Advent of Information Technology and the Rise of VoIP
Chapter Two - The Session Initiation Protocol (SIP) as One of the Foundations of VoIP
Chapter Three - Standards for Voice Over IP Implementations
Chapter Four - Proofs of Concept on the Security and Efficiency of VoIP Implementation
Chapter Five - Conclusion
From the Paper "Any type of implementation, procedures or processes in existent today should and must adhere to certain standards and industry best practices. VoIP is no different and in this chapter, available standards will be examined in order to determine the validity of the parameters used in the various proofs of concept performed by different proponents. Beginning with RFC 3261, the document will be benchmarked against two United States government publications that define not only VoIP implementation but security considerations involved in the planning up to the operations stage."

From the Paper "A firewall is a users best defense from invasions by outside intruders. It will protect unwanted traffic on a PC or network from an outsider. A firewall acts as a buffer between the PC or network and all external networks, especially the Internet.
"Michael Palmer defines a firewall as being a "software, hardware or combination of both employed to restrict who has access to a network, to specific segments, or to certain resources.""
Abstract This paper examines data communications and networking and illustrates how networksecurity aspects apply. The paper presents an understanding of the status, outlook and trends regarding networksecurity technology. An extensive search of academic journals, trade publications and other related magazines regarding networksecurity, is provided. Although this paper takes into consideration the business applications of the topic, it also presents some technical details.
From the Paper "Before we had such a complex world of information technology, computers were always single or 'dumb' terminals that could only accept information from their mainframe overseers. "It's depressing how often we see that those who don't remember history are doomed to repeat it. When cordless phones and the first analog cell phones hit the market, anybody with a scanner that operated at the right frequency could easily listen to calls not intended for them." (Gast, 2002) Security was easy to manage because only a few people had access to the mainframes. But today, even the most basic network has many individual nodes more powerful than the mainframes of just a few years ago. Networks now have access to the Internet which basically opens up the world to users."
An exploration of the connection between a company's networksecurity and employees who take work home with them and the drastic effects taking work home has on company systems.
Abstract This paper discusses how networksecurity is something that top management, IT professionals, and end users need to be aware of. It discusses how all three groups look at this issue from different perspectives but each perspective is importantant to implementing a safe securenetwork for a business. The paper shows that, by providing anti-virus programs for home users, implementing appropriate network usage procedures, and providing proper training and education, companies can limit the amount of malicious infections that infiltrate their systems.
From the Paper "In order to be more productive, many employees have started to take work home with them. Removable media devices can hold large volumes of data, and reduced prices have made devices such as USB tokens and MP3 players affordable to all (Executive Summary). The ease and convenience of massive storage devices has enabled users to transport massive amounts of data to and from the comfort of the user's home. Unfortunately, many users do not have the security devices installed on their personal computer that the company has on its network. Because they do not have basic antivirus protection, they are susceptible to infection (Vamosi, 2004). If an employee's home computer is infected with a virus it can easily be transferred to files downloaded to and from a USB token without the user's knowledge. "
Abstract This paper consists of a brief introduction of networking and TCP/IP and Internet working. Also discussed are risk management, network threats, firewalls, and special- purpose network devices. The paper provides a better insight into the general aspects of security and allows the reader to get a better understanding of how to reduce and manage risk factors at the workplace and at home.
From the Paper "It is very difficult to actually be able to estimate security as to what level of risk in terms of security is acceptable. The most important factor to be able to decide as to what security actually implies to an organization. After deciding upon this we can analyze the rest of the factors in connection to the policies of the network. The various projects and systems can also be broken down in to their components and after this it also become much easier to decide as to the proposed will actually conflict with the security practices and policies. A lot of people give a huge amount of money for security but do not like it to interfere in the business. It is very essential that we build system and networks in a manner that the user is not affected with the security system that is present around him. Individual users who do not like the over restrictive security and system policies will think of ways of getting around it. It is essential to get the opinion of such individuals and let them know as to why what is being done is done so. (Network Security and web services Deployment)"

The various applications, protocols and algorithms are discussed, followed by a brief discussion of how the technology works. Then, the advantages of IPSec, including e-commerce and mobile computing, are discussed briefly. A table of contents is included to make navigating the headings and subheadings easier.
Abstract This paper addresses the importance of having a written and enforceable Computer NetworkSecurity 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.
From the Paper "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 looks at a case where offices are linked to the Internet using a server system intended to provide sufficient security for data sent or received, for stored records and for company processes. The paper discusses the vulnerabilities in this system and considers solutions that range from managerial, meaning the writing and dissemination of guidelines, to the technological, meaning the use of monitoring or blocking software. The paper concludes that vigilance can keep the most serious threats to a minimum.
From the Paper "In choosing the technology solution for a given data need, certain features should be considered. This means making a careful study of needs, the complexity of the infrastructure, the resources and skill level of the IT staff, and the capital available for investment. To make an informed choice, the manager should consider four areas: reliability, scalability, security, and total cost of ownership. The meaning of reliability is self-evident, and it means features to ensure the integrity of the data and to assure that the data is safe in the event of a system failure or disaster."
