Network Security is a comprehensive resource written for anyone who plans or implements network security measures, including managers and practitioners. It offers a valuable dual perspective on security: how your network looks to hackers who want to get inside, and how you need to approach it on the inside to keep them at bay.
You get all the hands-on technical advice you need to succeed, but also higher-level administrative guidance for developing an effective security policy. There may be no such thing as absolute security, but, as the author clearly demonstrates, there is a huge difference between the protection offered by routine reliance on third-party products and what you can achieve by actively making informed decisions. You'll learn to do just that with this book's assessments of the risks, rewards, and trade-offs related implementing security measures.

1.0 Introduction
If you were to talk with someone whose job it is to implement network security, you would hear a lot about buffer overflows, vendor patches, denial of service attacks, and so on. But network security is much broader than the details of attacks and defenses against them. A good network security scheme begins at the top of an organization, with extensive planning to determine where the organization should be concentrating its security efforts and money.
In this chapter, you will be introduced to many of the basic concepts behind a security strategy, including the general sources of security threats (to give you a framework for formulating a security policy) and the role of organizational security policies. The chapter concludes by looking at the concepts behind a security audit to check compliance with security policies as well as the actual security of the network.
