In the last chapter, we discussed the basics of network security. Among the issues that we briefly touched on are the techniques and best practices that are currently being used by many security personnel in a variety of networks that make up the communication infrastructure. In this chapter, we are going to start with what is considered to be the most basic of all security techniques—security.policy. We will discuss several issues about security policy, like what constitutes a good policy and how to formulate, develop, write implement, and maintain a security policy.
