The first 4 chapters told me what unnecessary ports I needed to shutdown and some nice exmples of using SSH to get into my Routers. That alone was worth the price of the book. Even though we use a Cisco VPN a little more secuirty wouldn't hurt. I do however agree with the past reviewer in that some debugging instances would help also.

If you are familiar with TFTP and configuring your router than you will have no problems with the examples in the book.

Where is the Hardening Cisco PIX firewall book!?
