Preparing yourself for intrusions

Wednesday, 26 January 2005, 8:02 AM EST

In years past, the term intrusion detection had a general meaning: the methods by which an administrator learned about system intrusions, or about attempts to intrude, on a given system. As in most technological areas, intrusion detection has evolved and specialized. Why worry about intrusion detection if you have a good firewall? Just remember: no lock is unpickable. Firewalls have holes so that services can run (web, mail, and so on). Where there's a hole, there's a way.

We also show you how to use common Linux tools and shell scripts to maintain the security of your system, keep a watchful (and automated) eye on your system, and offer some solutions to common intrusion detection problems.
