*CROSS POSTED*
The always gregarious folks at the U.S.A's NSA re-released the 182 page
3rd edition of "Guide to the Secure Configuration of Red Hat Enterprise
Linux 5" about a week ago.
This is the single most comprehensive document for hardening your RHEL5
Tikanga system. Indeed, if you do /everything/ in this publication,
your system is probably 'bricked'. But carefully applied, this helps to
close security cracks. The guide goes well beyond common sense
precautions and includes some lesser known steps.

The previous editions of the guide were found at different URLs at the
NSA site so no guarantee exists that this will stay put. Although the
document lacks an index, it has a /href'd/ table of contents. The text
even contains some hot links to referenced civilian sites for authority.
Enjoy.
