Review: The Book of Postfix: State-of-the-Art Message Transport
I was very impressed with "The Book of Postfix" by authors Ralf Hildebrandt
and Pattrick Koetter and feel that it is an incredible Postfix reference.
It gives a great overall view of the operation and management of Postfix
in an extremely systematic and practical format. It flows in a logical
manner, is easy to follow and the authors did a great job of explaining
topics with attention paid to real world applications and how to avoid
many of the associated pitfalls. I am happy to have this reference in
my collection.

* Review: Deep Inspection Firewalls
6th, May, 2005
If it were on public display, this portion of our Firewall Blowout
would be the geek equivalent of the Chicago Auto Show. Our Chicago
Neohapsis partner labs focused on the muscle cars: enterprise-class,
gigabit-capable network firewall appliances and turnkey systems that
support high-availability stateful failover, VPNs and centralized
management as well as DI (deep inspection), which we define as having
the ability not only to perform stateful packet filtering, but also
to inspect packet payloads higher up the OSI model using specific
attack signatures and Layer 7 protocol engines.

support, and a nicely compiled nvidia driver. Wonderful. Absolutely

* Why Snort makes IDS worth the time and effort
5th, May, 2005
The decision of whether to implement an intrusion-detection system
