Linux 101: Best practice for security integrity auditing and recovery

Two critical security considerations that are closely related to one another are ignored all too often: integrity auditing and recovery. This document is an overview of good security integrity auditing and recovery practices using a Linux operating system.

Computer and network security involves several important elements. A system administrator must choose secure software, install and configure security systems like firewalls, and keep up with vulnerability patching, among other tasks. Two critical security considerations that are closely related to one another are ignored all too often: integrity auditing and recovery.

Too often, a sysadmin will get all the basic security measures in place, set up a well-secured system, and figure his job is done unless something goes horribly and obviously wrong. It is important, though, to regularly check the systems in your area of responsibility to make sure they haven't been compromised, and to know what to do if they have. Sometimes, a security cracker can penetrate security and gain complete control of your system without you ever knowing about it until it is far too late to prevent the damage that will be done, and sometimes a security breach might be cursorily "cleaned up" so that no visible signs of cracked security remain but, hidden from view, trojans, rootkits, and other deceptive security issues might still exist.
