Book review: Cisco Secure Firewall Services Module

I was really looking forward to reading the Cisco Secure Firewall Services Module (FWSM) book from Cisco Press. I had some exposure to PIX and pretty solid understanding of how firewalls and NAT work (otherwise I would probably fail a few CCIE recertification exams :), but quickly got lost on FWSM when I was invited to help troubleshooting a nasty 7600/FWSM problem, so it was time to catch up.

For me, the book was (apart from a few annoying omissions and typos) a perfect fit, but if you’re looking for “best practices for securing networks with FWSM” (what the subtitle advertises) you’ll probably be disappointed.

  1. Have you read the 'Cisco ASA, PIX and FWSM Firewall handbook'? I've read that one but was hoping for more information on the FWSM, specifically in transparent mode. Maybe this new book is the one I'm looking for.

  2. The one I've read has plenty of information on the transparent mode (including deployment and design scenarios). If that's what you're looking for, try it.

  3. This is really a superb books. I have not seen any book of FWSM which can explain the design & integration of FWSM.
