Amazon.com just posted my four star review of McGraw-Hill/Osborne's Hacking Exposed: Cisco Networks. From the review:
I've always been a fan of Osborne's Hacking Exposed books (although subjects like "Computer Forensics" don't seem to fit the spirit of the series). I previously read Wi-Foo: The Secrets of Wireless Hacking by the same authors who wrote Hacking Exposed: Cisco Networks (HECN). Comparing the two books, I agree with previous reviewer Sean E. Connelly; I think HECN was rushed to market. The book needs better technical review, proofreading, and copyediting as well. Nevertheless, I still recommend reading HECN -- it's a unique book on a critical subject.
