Managing Cisco Network Security

As I am currently working on my Cisco Security Specialization (CSS) I have read all books related to CSS. Out of the four books this is definately one of the most valuable references when it comes to Cisco network security. This book is well-structured, referencing all the potential threats and countermeasures that exist to network security. I really praise the author for his clear explaination of IPSec and PIX concepts. For those seeking to pass the MCNS 2.0 exam, this is a great reference and study guide. All necessary topics are covered, except the Cisco VPN Client, which has been added to the MCNS exam during version 2.0. Overall, a great book by a great author, a definite must-have for the future CSS1, CCIP/CCIE security specialists.
