...constantly attacking and attempting to infiltrate any and all defenses posed by a target computer. An attacker can gain personal information, such as finance data, including credit card information as well as account numbers, and other important information relevant to your life. These attempts can eventually lead to success and jeopardize the people being attacked. These attacks are becoming more sophisticated and complex as well, meaning not only that technologies need to be evolved and enhanced, but also that the user needs to be more conscious than ever of exactly what they are doing on their systems. According to Dictionary.com Network security is “The protection of a computer network and its services from unauthorized modification, destruction, or disclosure”. This means that any person that attempts to access a computer network or any of its components without explicit permission of the network administrator, is in violation of that computer network. While there are many laws and regulations stating that these attempts are illegal, the illegal attempts are one of the fastest growing crimes in modern society today. This is because they are very...

...PA r T O N e Foundations of Network Security Fundamentals of Network Security 2 Firewall Fundamentals 43 VPN Fundamentals 79 Network Security Threats and Issues 111 CHAPTer Fundamentals of Network Security 1 C OMPUTER NETWORK SECURITY is very complex. New threats from inside and outside networks appear constantly. Just as constantly, the security community is always developing new products and procedures to defend against threats of the past and unknowns of the future. As companies merge, people lose their jobs, new equipment comes on line, and business tasks change, people do not always do what we expect. Network security configurations that worked well yesterday, might not work quite as well tomorrow. In an ever-changing business climate, whom should you trust? Has your trust been violated? How would you even know? Who is attempting to harm your network this time? Because of these complex issues, you need to understand the essentials of network security. This chapter will introduce you to the basic elements of network security. Once you have a firm grasp of these fundamentals, you will be well equipped to put effective security measures into practice on your organization’s network. While this textbook focuses on general network security, including firewalls and virtual private networks (VPNs), many of the important basics of network security are introduced in this chapter. In Chapters 1–4, network security...

...CHAPTER Firewall Fundamentals 2 T o some network administrators, a firewall is the key component of their infrastructure’s security. To others, a firewall is a hassle and a barrier to accomplishing essential tasks. In most cases, the negative view of firewalls stems from a basic misunderstanding of the nature of firewalls and how they work. This chapter will help dispel this confusion. This chapter clearly defines the fundamentals of firewalls. These include what a firewall is, what a firewall does, how it performs these tasks, why firewalls are necessary, the various firewall types, and filtering mechanisms. Once you understand these fundamentals of firewalls, you will be able to look beyond the unschooled opinions, common mythology, and marketing hype surrounding them, and the crucial benefits of effective firewall architecture will become clear. Like any tool, firewalls are useful in solving a variety of problems and in supporting essential network security. Chapter 2 Topics This chapter covers the following topics and concepts: • What a firewall is • Why you need a firewall • How firewalls work and what they do • What the basics of TCP/IP are • What the types of firewalls are • What ingress and egress filtering is • What the types of firewall filtering are • What the difference between software and hardware firewalls is • What dual-homed and triple-homed firewalls are • What the best placement of a firewall is 43 Chapter 2 Goals When you complete...
