وای‌فویو: رازهای هک بی‌سیم

A guide to penetrating and defending wireless networks, and to hacking wireless networks. It helps you master the attacker's arsenal of hardware and software tools: knowledge for crackers and auditors. It also helps you learn systematic counter measures for building hardened wireless 'citadels' including cryptography-based techniques.

Written for system administrators, this book focuses on penetration testing of 802.11-based wireless networks to identify weaknesses, and recommends what needs to be done to stop a determined hacker from taking over a network. The authors, who work for Arhont in Britain, describe mutually authenticated IPSec implementations, authentication methods alternative to 802.1x, proper network design, positioning and secure gateway deployment, protocol filtering, SSL/TLS use, ssh port forwarding, and intrusion detection systems.

WarDriving-or moving around an area to map wireless access points-presents an opportunity for those interested in raising awareness of wireless connectivity and security vulnerabilities; an opening for those looking to contribute connectivity through deliberately opening access; and a security threat to those who fail to protect their networks-even though ethical WarDrivers point out that they eschew unauthorized network use. WarDriving teaches how to WarDrive, from necessary tools to useful software; each chapter ends with a summary, bullet points, and FAQ. Later chapters discuss how to attack and how to defend wireless networks, making this useful for readers wanting to protect their networks. The main focus, however, may find a narrow audience in most libraries; those seeking books on securing their network will want to supplement with more thorough guides, and those interested in WarDriving may already be conversant with the tools and ideas discussed. A supplemental purchase for larger libraries. Wi-Foo covers similar ground and discusses similar utilities, yet it goes much deeper into the nuts and bolts of both breaking into and defending wireless networks. Some more technical sections are balanced out by step-by-step explanations of security basics and patterns of attack. Extensive appendixes range from antenna irradiation patterns to war-chalking symbols to a penetration testing template. Wireless security is an ever-growing issue, which makes this thorough guide recommended for larger libraries. Copyright 2004 Reed Business Information.

"This is an excellent book. It contains the 'in the trenches' coverage that the enterprise administrator needs to know to deploy wireless networks securely." --Robert Haskins, Chief Technology Officer, ZipLink Wi-Foo: The Secrets of Wireless Hacking is the first practical and realistic book about 802.11 network penetration testing and hardening. Unlike other books, it is based on a daily experience of breaking into and securing wireless LANs. Rather than collecting random wireless security news, tools, and methodologies, Wi-Foo presents a systematic approach to wireless security threats and countermeasures starting from the rational wireless hardware selection for security auditing and finishing with how to choose the optimal encryption ciphers for the particular network you are trying to protect.
