Instead, the book is written for both those new to the field and the professionals that need a good reference manual lying on their shelves. This well-written volume covers a broad range of security topics, with valuable tips on making your system more secure.

Security is a really important topic.
Your users don't understand it. If you could only purchase one book on Internet security, this is the one you'd want. The book explains in detail the ways that intruders can get into a system, as well as how to detect them, clean up after them, and even prosecute them if they do get in. It's complete, covering both host and network security, and doesn't require that the reader be a programmer or a UNIX guru to use it. In this security-conscious age, this book is an essential reference for anyone who is responsible for a UNIX system.
