A Cisco book not limited to cisco devices.

This is my first ethical hacker book, it is very exciting!!. Covers almost every aspect of penetration testing in good length. Explains many types of scans a penetration tester can and can't perform, gives specific reason why you should choose to perform those different types of scan, which ones you should use to keep from being detected.
It gives an easy to understand explanation of types of attacks, how to performed, tools needed, and how to protect/detect from such attacks. It also discusses the difficulty of detecting certain of attacks.
It also has an entire chapter regarding the legal considerations and implication of penetration testing. And the great thing about this book is that even though it is cisco book, it covers many divices and operatings system.
