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 countermeasures 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 802.11i, 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.

Build, Deploy and Maintain a “Homebrew” Wi-Fi Network
Create a Low-Cost/High-Yield Development Roadmap for Wireless Enthusiasts, Households, Small Businesses and Community Groups
Customize Wireless Operating Systems, Install Antennas, Build Solar-Powered Access Points and More

A few years ago, wireless internet access was just a glint in the eyes
of the IT industry. Today, most notebook PCs ship with built-in Wi-Fi
capability, and Wi-Fi access points have become as important as the
espresso machines at the neighborhood Starbucks. Wireless Hacking
provides a low-cost/high-yield blueprint for wireless enthusiasts,
households, small businesses and communities. After reading this book,
you will be able to build, deploy and maintain a “homebrew” Wi-Fi
network. And if you just want some geek fun, Wireless Hacking won’t disappoint. You will be challenged! Written by members of the pioneering SoCalFreeNet Wireless Users Group, Wireless Hacking
delivers a series of interrelated projects, with full integration of
both hardware and software hacks. Some of the wireless hacks in this
book include:

• Use existing Ethernet cables to provide low-voltage power to Access Points with no additional source of electricity.
• Install Linux and FreeBSD on low-cost (under $150) Soekris single-board computers.
• Modify the firmware of your Linksys WRT54g.
• Construct Solar Powered Access Points and Repeaters for your Wi-Fi network.
• WarDrive for wireless access points with tools like Kismet and NetStumbler.
• Install an antenna without killing yourself or changing the earth’s orbit.
• Expand your Wi-Fi network beyond one box and 50 users with MESH network topology.

Wireless sensor networks promise an unprecedented fine-grained
interface between the virtual and physical worlds. They are one of the
most rapidly developing new information technologies, with applications
in a wide range of fields including industrial process control,
security and surveillance, environmental sensing, and structural health
monitoring. This book is motivated by the urgent need to provide a
comprehensive and organized survey of the field. It starts by showing
how the core challenges of energy efficiency, robustness, and autonomy
are addressed in these systems by networking techniques across multiple
layers. The topics covered include network deployment, localization,
time synchronization, wireless radio characteristics, medium access,
topology control, routing, datacentric techniques, and transport
protocols. Ideal for researchers and designers seeking to create new
algorithms and protocols, and engineers implementing integrated
solutions, it also contains many exercises and can be used by graduate
students taking courses in Networks.

Cisco Wireless LAN Security
is an in-depth guide to wireless LAN technology and security,
introducing the key aspects of 802.11 security by illustrating major
wireless LAN (WLAN) standards that can protect the entire network.
Because a WLAN is less effective as an isolated piece of the network,
this book emphasizes how to effectively integrate WLAN devices into the
wired network while maintaining maximum security.

Cisco Wireless LAN Security
covers the spectrum of WLAN security, including protocols and
specifications, vulnerabilities and threats, and, especially,
deployment patterns and design guidelines. With a unique combination of
theory and practice, this book addresses fundamental wireless concepts,
such as WEP, and innovations, such as EAP, switching, and management.
Each chapter includes detailed illustrations, checklists, design
templates, and other resources. You will also find generic wireless
deployment patterns based on real-world customer installations and
functional examples of architecture, design, and best practices.

The popularity of wireless networking has grown exponentially over
the past few years, despite a general downward trend in the
telecommunications industry. More and more computers and users
worldwide communicate via radio waves every day, cutting the tethers of
the cabled network both at home and at work.

Wireless technology changes not only the way we talk to our
devices, but also what we ask them to do. With greater flexibility,
broader range, and increased mobility, wireless networks let us live,
work, and think differently. Wireless networks also open up a vast
range of tasty new hack possibilities, from fine-tuning network
frequencies to hot-rodding handhelds.

The second edition of Wireless Hacks, co-authored by Rob
Flickenger and Roger Weeks, brings readers more of the practical tips
and tricks that made the first edition a runaway hit, selling nearly
30,000 copies. Completely revised and updated, this version includes
over 30 brand new hacks, major overhauls of over 30 more, and timely
adjustments and touchups to dozens of other hacks introduced in the
first edition. From passive network scanning to aligning long-distance
antennas, beefing up wireless network security, and beyond, Wireless Hacks answers real-life networking needs with direct solutions.

Flickenger and Weeks both have extensive experience in systems and
network administration, and share a passion for making wireless more
broadly available. The authors include detailed coverage for important
new changes in specifications and in hardware and software, and they
delve deep into cellular and Bluetooth technologies.
