Linux Security 101

An introduction to Linux security

This is an introduction to security for Linux systems. The emphasis is on introduction.

The focus is on the basics in areas such as physical security, locking the console, securing files and network connections.

This talk is intended to give a broad introduction to a very large subject with a brief overview of some of the more important security tools. Pointers to more advanced security topics are listed in the summary.


These pages form part of a talk given to the Linux Users of Victoria group in February 1998.
