This work shows network administrators and security testers how to enter the mindset of a malicious hacker and perform penetration testing on their own networks. It is thoroughly updated with more than 30 percent new content, including coverage of Windows XP SP2 and Vista, a rundown of new security threats, expanded discussions of rootkits and denial of service (DoS) exploits, new chapters on file and database vulnerabilities and Google hacks, and guidance on new hacker tools such as Metaspoilt. Topics covered include developing an ethical hacking plan, counteracting typical hack attacks, reporting vulnerabilities to upper management, managing security changes, and training end-users on how to avoid becoming victims of social engineering. The author is a veteran security pro who has performed penetration testing for nearly two decades and is a regular speaker at security conferences such as RSA.Contents: Foreword. Introduction.
