LINUX SECURITY

For companies that depend on Linux systems, protection against internal and external threats is critical. This tutorial will guide you in the finer points of Linux security, how to configure tools and utilities to minimize exposure and detect intrusions.

This newsletter will benefit IT professionals who work with Linux and are responsible for system security.

Brian Hatch is Chief Hacker at Onsight, Inc., and author of Hacking Linux Exposed and Building Linux VPNs. He believes there's only one piece of software that he considers essential for every machine, and that's vi. Everything else is negotiable. Brian can be reached at brian@hackinglinuxexposed.com.
