Keeping a network secure is a time-consuming process that requires a lot of attention to detail. Similar to troubleshooting faulty equipment, maintaining network security is also a time-consuming practice that involves the following:

  • Detection of a security breach or network intrusion

  • Finding the cause of a security breach

  • Finding the method of an intrusion

  • Educating users about security on a continual basis

This chapter examines security from two different angles: first, preventive measures that can be used to help keep problems from occurring in the first place, and second, tools and techniques to discover these kinds of problems.
