This offbeat, non-technical book looks at what hackers do, how they do it, and how you can protect yourself. The third edition of this bestseller (over 150,000 copies sold) adopts the same informative, irreverent, and entertaining style that made the first two editions a huge success. Thoroughly updated, this edition also covers rootkits, spyware, web bugs, identity theft, hacktivism, wireless hacking (wardriving), biometrics, and firewalls.
