Mastering FreeBSD And OpenBSD Security

FreeBSD and OpenBSD are increasingly gaining traction in educational institutions, non-profits, and corporations worldwide because they provide significant security advantages over Linux. Although a lot can be said for the robustness, clean organization, and stability of the BSD operating systems, security is one of the main reasons system administrators use these two platforms.There are plenty of books to help you get a FreeBSD or OpenBSD system off the ground, and all of them touch on security to some extent, usually dedicating a chapter to the subject. But, as security is commonly named as the key concern for today's system administrators, a single chapter on the subject can't provide the depth of information you need to keep your systems secure.FreeBSD and OpenBSD are rife with security "building blocks" that you can put to use, and Mastering FreeBSD and OpenBSD Security shows you how. Both operating systems have kernel options and filesystem features that go well beyond traditional Unix permissions and controls. This power and flexibility is valuable, but the colossal range of possibilities need to be tackled one step at a time. This book walks you through the installation of a hardened operating system, the installation and configuration of critical services, and ongoing maintenance of your FreeBSD and OpenBSD systems.Using an application-specific approach that builds on your existing knowledge, the book provides sound technical information on FreeBSD and Open-BSD security with plenty of real-world examples to help you configure and deploy a secure system. By imparting a solid technical foundation as well as practical know-how, it enables administrators to push their server's security to the next level. Even administrators in other environments--like Linux and Solaris--can find useful paradigms to emulate.Written by security professionals with two decades of operating system experience, Mastering FreeBSD and OpenBSD Security features broad and deep explanations of how how to secure your most critical systems. Where other books on BSD systems help you achieve functionality, this book will help you more thoroughly secure your deployments.

O'ReillyMastering FreeBSD and OpenBSD SecurityBy Yanek Korff, Paco Hope, Bruce PotterFirst Edition March 2005ISBN: 0-596-00626-8464 pages, $49.95 US[...]This book has been long awaited as the *BSD community has been lacking the number of security geared books compared to the Linux and Windows communities. I found that this book is almost the equal of "Linux Server Security", but for OpenBSD and FreeBSD. With OpenBSD being said to be one of the most secure operating systems, you would think there would be more books about the security other than the normal online documentation.I'm glad O'Reilly finally put out this book as it covers a broad area of security within OpenBSD and FreeBSD.This covers *BSD basics, initial install and hardening of the specific OS, security practices, running secure servers (DNS, Mail, Web), firewall, intrusion detection, system audits, incident response, and forensics. This is a broad coverage of security, but I wish on some of the specifics they would have went into detail discussing.Some points I wish were added in detail was coverage on OpenNTPD's security and/or atleast mentioning that it is contained within OpenBSD. Another would be more coverage of Qmail on FreeBSD/OpenBSD as there really wasn't much more than a mention of Qmail and basic information. Compared to the details given to Sendmail and Postfix, Qmail info was really slacking. The last point I would like to mention that I found lacking was possibly a more in-depth guide to CARP and what it's capable of doing. The main thing dealing with CARP that I would have liked to see would be about load balancing firewalls using CARP and PFSYNC.

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.First, I think MFAOS:2E should address FreeBSD, OpenBSD, and NetBSD. It's appropriate to read a book only about ONE of the BSDs, or all three of the BSDs. It's odd to cover FreeBSD and OpenBSD but not NetBSD. I think DragonFly BSD's miniscule userbase puts it on the fringe, and Mac OS X is not BSD.Second, the authors should rigorously concentrate on covering BSD-specific administration and security issues. I do not need to read about generic security issues in Ch 1, or standard DNS/Mail/Web attacks in Chs 5/6/7. I definitely did not need YASD (Yet Another Snort Doc) in Ch 9 -- especially when ACID is explained as the console of choice. (BASE replaced ACID in Sep 04). I do not need the advice on incident response and forensics found in Ch 11. MFAOS should be a more of a BSD book and less of a security book.Removing all of this generic material in a second edition would provide room to focus on BSD-specific material not found elsewhere.
