Amazon.com just posted my four star review of Mastering FreeBSD and OpenBSD Security by Yanek Korff, Paco Hope, and Bruce Potter. From the review:
Mastering FreeBSD and OpenBSD Security (MFAOS) more or less delivers on its subtitle: "Building, securing, and maintaining BSD systems." The book is chock full of absolutely sound administration advice from three experts with plenty of operational experience. I am also thrilled whenever I find a new BSD title on bookshelves. However, I believe a second edition of this book should be radically altered to better deliver value to the reader.
Note: I am in a somewhat awkward position as I write this review, since I know one of the authors as a fellow local security professional. I've spoken at a conference he organizes and I even have all three authors' signatures on my copy of MFAOS! Still, I hope they will consider incorporating my ideas when O'Reilly asks for a second edition.
I forgot to mention that I agree with Shirkdog's review -- a book on BSD security absolutely should have included Systrace.
Read the review to see my suggestions. If you think they are helpful, please vote them so at Amazon.com. Thank you.
