Kevin Fenzi,

v0.9.5, 1 March 1998

This document is a general overview of security issues that face the administrator of linux systems. It covers general security philosophy and a number of specific examples of how to better secure your linux system from intruders. Also included are pointers to security related material and programs. NOTE: This is a beta version of this document. Improvements, constructive criticism, additions and corrections are gratefully excepted. Due to my despam filter, you will need to mail me to get a despam key to mail me. Sorry for the trouble. To avoid this make sure you have "linux", "security" or "HOWTO" in the subject line of your mail.
