"This book works in tandem with the OpenBSD's manual pages. As a result,
it will help many users grow and get the most from the system."
—Theo
de Raadt, OpenBSD project leader.
"The OpenBSD system intimidates many administrators who would benefit
from using it. This book lets people start much higher up on the curve. Secure
Architectures with OpenBSD not only presents the hows, but also shows some of
the whys that only insiders know."
—Mike Frantzen, NFR Security
"Secure Architectures with OpenBSD explains all of the tasks an administrator
has to know about to successfully maintain an OpenBSD server. It helps the reader
save time by condensing the vast amount of information available in man pages
into a compact form, reducing unneeded information, and explaining other things
in much more detail and prose than a man page can afford."
—Daniel
Hartmeier, the OpenBSD Project
"This book will become the de facto text for OpenBSD administration. Unix
and BSD books abound, but none cover OpenBSD with the clarity and expertise
of Palmer and Nazario. They explain the optimal way to configure and administer
your OpenBSD machines, with a keen eye to security at all stages."
—Brian
Hatch, coauthor of Hacking Exposed Linux and Building Linux Virtual Private
Networks
Descended from BSD, OpenBSD is a popular choice for those who demand stability
and security from their operating system. No code goes into OpenBSD without first
undergoing a rigorous security check, making it a terrific choice for Web servers,
VPNs, and firewalls.
Secure Architectures with OpenBSD is the insider's guide
to building secure systems using OpenBSD. Written by Brandon Palmer and
Jose Nazario, this book is a how-to for system and network administrators
who need to move to a more secure operating system and a reference for
seasoned OpenBSD users who want to fully exploit every feature of the system.
After getting readers started with OpenBSD, the authors explain system
configuration and administration, then explore more exotic hardware and
advanced topics. Every chapter of the book addresses the issue of security
because security is integrated into almost every facet of OpenBSD. Examples
appear throughout the book, and the authors provide source code and system
details unavailable anywhere else. This book goes beyond the basic book
and tells readers what they are going to be using well after they've installed
a system.
Key topic coverage includes:
-
Installation and upgrade details
-
Basic system usage in OpenBSD versus other Unix systems
-
Third-party software via packages and the ports tree
-
SMTP services in OpenBSD
-
Web services with Apache
-
Using OpenBSD as a firewall
-
OpenBSD as a Kerberos V client and server
-
Use of Ipsec
-
Configuration and use of IPv6
-
Network intrusion detection
Secure Architectures with OpenBSD takes you inside OpenBSD,
giving you the insights and expertise no system manual can provide. The
companion Web site tracks advances and changes made to the operating system,
and it contains updates to the book and working code samples.

Add this to your OpenBSD library
I have been using OpenBSD from version 2.9 and I will leave it up to the reader to read all about the features this fantastic OS provides from another source!
Secure Architectures with OpenBSD provides the new user a good introduction and gently takes the reader into unleashing the power of OpenBSD towards the end of the book.
I specifically enjoyed the chapters on PF, IPSec, Kerboros, and Systrace. Although the OpenBSD team maintains the highest standards when it comes to documentation (man pages), this book will certainly compliment it by providing the information in a clean/concise manner.
Thanks to Jose (undeadly.org) and Brandon (crimeslab.net) for providing a great resource to those who are new and veterans of the OpenBSD community.
