Amazon.com just posted my five star review of Secure Architectures with OpenBSD. From the review:
"About a year ago I read and reviewed Michael Lucas' excellent "Absolute OpenBSD." That book covered OpenBSD 3.2 and the CURRENT of that time, pre-3.3. Palmer and Nazario's "Secure Architectures with OpenBSD" (SAWO) addresses OpenBSD 3.4, which at the time of writing is just behind the current release (3.5). Lucas' book is an excellent introduction to OpenBSD by a relative outsider; SAWO is a more detailed discussion by insiders. Each has its strengths and I highly recommend both."
