Computer System and Network Security
Distrust and caution are the parents of
security.

— Benjamin Franklin

We will bankrupt ourselves in the vain search
for absolute security.

This page remains under construction,
just as your security policy should.
This material is an addition to any reference
material provided elsewhere.
This forum provides additional information,
and lists references and URL's that come up during some courses I teach.

Remember that installing some tools, and even taking security quite
seriously on an on-going basis, does not make you secure!
Maybe a little more secure
(or, for the pessimists in the crowd, a little less at risk),
but there is no such thing as a completely safe system.
Hence some lawyer repellent, er, I mean, disclaimer:
The following are no more than suggestions.
There is no guarantee that they will make your system secure.
Mention here of a commercial product is by no means an endorsement — I'm just
trying to direct you to several available tools, and I may have only one
such example handy right now.
Use this information as a tool, in addition to what you have already learned.

Make sure you understand your systems well, and set them
up properly!
