This is the definitive guide to penetrating and defending wireless networks. Straight from the field, this is the definitive guide to hacking wireless networks. Authored by world-renowned wireless security auditors, this hands-on, practical guide covers everything you need to attack - or protect - any wireless network. The authors introduce the 'battlefield,' exposing today's 'wide open' 802.11 wireless networks and their attackers. One step at a time, you'll master the attacker's entire arsenal of hardware and software tools: crucial knowledge for crackers and auditors alike. Next, you'll learn systematic counter measures for building hardened wireless 'citadels' including cryptography-based techniques, authentication, wireless VPNs, intrusion detection, and more. Coverage includes: step-by-step walkthroughs and explanations of typical attacks; building wireless hacking/auditing toolkit: detailed recommendations, ranging from discovery tools to chipsets and antennas; wardriving: network mapping and site surveying; potential weaknesses in current and emerging standards, including 802.1 1i, PPTP, and IPSec; implementing strong, multilayered defenses; wireless IDS: why attackers aren't as untraceable as they think; wireless hacking and the law: what's legal, what isn't. If you're a hacker or security auditor, this book will get you in. If you're a netadmin, sysadmin, consultant, or home user, it will keep everyone else out.
