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. 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.

Now this was a good book I have used PFCTL for a couple of years, but have needed a book for reference that was easy to understand. I found this book to be exactly that. I recommend this book to anyone that needs a good reference on pfctl firewall. Much appreciated, and will be used a lot.

This book had the exact pf NAT rule I needed, plus an example of the next NAT rule I will need when I have more than one subnet connected to my desktop and I want the subnets to be able to communicate with each other. If you need to use NAT rules with pf, this is your best source of information. Good Start This is a good start to get familiar with PF. There are a few spelling and grammatical errors that could be corrected in the next edition as well. A great intro for me This was the only book that came up so I decided to buy it.

Surprisingly, it was an easy read; completed in 4 days. The book does a good job of first going through installing obsd and then explaining some basic firewall setups. Following the first couple chapters, Artymiak goes into detail on all the nifty tricks PF can pull off.

It was a good stepping stone for me in building my own firewall. The appendix was quite usefull as well; which included basic pf. Artymiak is also involved in the obsd comunity as well, which is great. Maby in a future Edition? I like the direct approach taken by author Jacek Artymiak.

With few exceptions he ensures the reader is provided enough descriptions and working examples to implement Pf in an operational environment. Too often authors discuss important topics but fail to follow through on implementation. I hope he is working with an established publisher to ensure his next book has a wider audience. Portion of these reviews are from Amazon.



Chris marked it as to-read Oct 29, A few notes about the preceding. Books by Jacek Artymiak. Goodreads helps you keep track of books you want to read. View PF events live as they happen sort of like a tail-f.


Nebar Very dangerous unless running in simulation mode behind another firewall. This book is not yet featured on Listopia. Stefhen rated it it was amazing Apr 25, Robert added it Dec 04, Todd rated it really liked it Aug 14, So, just to be clear, the existing LAN goes on with its life, but without a connection to the Internet. You can switch the comment to disable the DHCP server if needed, and you can uncomment the pf line to disable pf for diagnostic tests. Want to Read Currently Guilding Read.
