The Ethical Hack: A Framework for Business Value Penetration Testing lays out the underlying methodologies and concepts required for performing successful and valuable penetration testing. The author discusses the process of penetration testing from a consultative point of view to ensure that the true value of the test is realized. He supplies a technical perspective of the common tools and exploits used by attackers along with the rational for why they are used and the information they provide the attacker. Finally, the text brings it all together in the form of attack scenarios to show the complete cycle of the attack from the hacker's perspective to the client's.
