Network Security Assessment (NSA) is the latest in a long line of vulnerability assessment / penetration testing books, stretching back to Maximum Security in 1997 and Hacking Exposed shortly thereafter. NSA is a good book with some new material to offer, but don’t expect to find deep security insight in this or similar assessment books. Noticably lacking in NSA is coverage of dial-up techniques, wireless insecurities, Novell vulnerabilities, and attacking clients rather than servers. Should NSA receive a second edition, I expect to see the book expand closer to the ‘behemoth’ it seems to deride.”]
