"Hardening" is the process of protecting a system and its applications against unknown threats. Hardening Linux identifies many of the risks of running Linux hosts and applications and provides practical examples and methods to minimize those risks.The book is written for Linux/UNIX administrators who do not necessarily have in-depth knowledge of security but need to know how to secure their networks.

In this book, you'll learn how to secure:

  1. The base operating system and firewall with iptables
  2. Connections to your hosts
  3. Fie systems and files
  4. Email servers
  5. IMAP and POP servers
  6. FTP servers

A quick reference of the procedures discussed in each chapter are summarized in Appendix C.

Hardening Linux by James Turnbull belongs on the shelf of anyone who installs and maintains Linux servers.
