Despite their popularity and wider deployment, IEEE 802.11 WLANs have been found to be vulnerable to security threats soon after their emergence requiring adoption of security measures. However, the introduced security measures didn’t provide solutions for Denial of Service (DoS) attacks. This book characterizes the DoS attacks based on their ease of applicability and the degree of severity they introduce, and evaluates countermeasures for efficiency and effectiveness in defending against the attacks. Among various DoS attacks, Authentication Request Flooding (AuthRF) and Association Request Flooding (AssRF), which are practical and needing lesser effort to cause damage, were selected for study using OMNET++ simulation environment embedding INET Framework. Designs and models have been developed for the selected attacks and for two versions of defenses: countermeasure and enhanced countermeasures. The studied attacks, AuthRF and AssRF, required less effort and caused severe damage. Both versions of defenses, Countermeasure and Enhanced countermeasure, are effective although they incur delay.
“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.
Written in Packt’s Beginner’s Guide format, you can easily grasp the concepts and understand the techniques to perform wireless attacks in your lab. Every new attack is described in the form of a lab exercise with rich illustrations of all the steps associated. You will practically implement various attacks as you go along. If you are an IT security professional or a security consultant who wants to get started with wireless testing with Backtrack, or just plain inquisitive about wireless security and hacking, then this book is for you. The book assumes that you have familiarity with Backtrack and basic wireless concepts.
With the advent of rich Internet applications, the explosion of social media, and the increased use of powerful cloud computing infrastructures, a new generation of attackers has added cunning new techniques to its arsenal. For anyone involved in defending an application or a network of systems, Hacking: The Next Generation is one of the few books to identify a variety of emerging attack vectors.
You’ll not only find valuable information on new hacks that attempt to exploit technical flaws, you’ll also learn how attackers take advantage of individuals via social networking sites, and abuse vulnerabilities in wireless technologies and cloud infrastructures. Written by seasoned Internet security professionals, this book helps you understand the motives and psychology of hackers behind these attacks, enabling you to better prepare and defend against them.

The Metasploit Framework is a powerful suite of tools that security researchers use to investigate and resolve potential network and system vulnerabilities. Metasploit: The Penetration Tester‘s Guide shows readers how to assess networks by using Metasploit to launch simulated attacks that expose weaknesses in their security. The book begins with the basics of information security and Metasploit, then proceeds to general and advanced techniques for penetration testing, including network reconnaissance and enumeration, server- and client-side attacks, devastating wireless attacks, and even targeted social engineering attacks. Whether readers are looking to secure their own networks or discover holes in others’, Metasploit is the definitive guide to penetration testing with this dynamic and flexible framework.
