libellum_aphrodite's review
4.0
Overall, very well written high level overview of security. This is a very deep topic, but Keith did a great job of providing helpful details without getting lost in the weeds. Although I appreciate this as a well-executed textbook, having a CCNP Route-Switch already made much of the reading repetitive and unenlightening for me, until the VPN piece, which explains the complex and typically brushed over topic of cryptology very well.
For those of you taking the CCNA Security exam, there are a few topics on the exam not covered in enough detail here, so be sure to look at another resource about common security threats, AH/ESP, and transport/tunnel modes. When I took the exam, the only configurations involved CCP. While reviewing the ASDM/command line configurations will probably help you internalize and understand the concepts, you will not (if the test from late 2012 is any indication) have to actually implement them during the test.
