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.
Wireshark is rated #2 in the Top 100 Network Security Tools by sectools.org. Wireshark is the world's most popular network analyzer tool. This book is the ultimate resource on Wireshark which is a MUST HAVE tool used by network IT professionals to troubleshoot, secure and optimize networks. Readers learn to capture wired and wireless traffic, focus on the cause of slow web browsing, identify why applications don't run properly across the network, locate the cause of poor VoIP call quality, determine why WLANs are plagued with problems and more. The author, Laura Chappell is the founder of Wireshark University and Chappell University and has been analyzing networks for over 20 years – the book is written in a clear manner with hundreds of screenshots for the visual learner. The foreword was written by Gerald Combs, creator of Wireshark. Wireshark Network Analysis covers the test objectives for the Wireshark Certified Network Analyst Exam and includes test questions and answers for all topics covered. Filled with 45 real-life case studies, Wireshark Network Analysis takes you inside small, medium and large corporations to see how they solved network problems in a more efficient, accurate way using Wireshark.

Contrary to popular belief, there has never been any shortage of Macintosh-related security issues. OS9 had issues that warranted attention. However, due to both ignorance and a lack of research, many of these issues never saw the light of day. No solid techniques were published for executing arbitrary code on OS9, and there are no notable legacy Macintosh exploits. Due to the combined lack of obvious vulnerabilities and accompanying exploits, Macintosh appeared to be a solid platform. Threats to Macintosh's OS X operating system are increasing in sophistication and number. Whether it is the exploitation of an increasing number of holes, use of rootkits for post-compromise concealment or disturbed denial of service, knowing why the system is vulnerable and understanding how to defend it is critical to computer security.
* Macintosh OS X Boot Process and Forensic Software All the power, all the tools, and all the geekery of Linux is present in Mac OS X. Shell scripts, X11 apps, processes, kernel extensions…it's a UNIX platform….Now, you can master the boot process, and Macintosh forensic software.
* Look Back Before the Flood and Forward Through the 21st Century Threatscape Back in the day, a misunderstanding of Macintosh security was more or less industry-wide. Neither the administrators nor the attackers knew much about the platform. Learn from Kevin Finisterre how and why that has all changed!
* Malicious Macs: Malware and the Mac As OS X moves further from desktops, laptops, and servers into the world of consumer technology (iPhones, iPods, and so on), what are the implications for the further spread of malware and other security breaches? Find out from David Harley.
* Malware Detection and the Mac Understand why the continuing insistence of vociferous Mac zealots that it “can't happen here” is likely to aid OS X exploitationg
* Mac OS X for Pen Testers With its BSD roots, super-slick graphical interface, and near-bulletproof reliability, Apple's Mac OS X provides a great platform for pen testing.
* WarDriving and Wireless Penetration Testing with OS X Configure and utilize the KisMAC WLAN discovery tool to WarDrive. Next, use the information obtained during a WarDrive, to successfully penetrate a customer's wireless network.
* Leopard and Tiger Evasion Follow Larry Hernandez through exploitation techniques, tricks, and features of both OS X Tiger and Leopard, using real-world scenarios for explaining and demonstrating the concepts behind them.
* Encryption Technologies and OS X Apple has come a long way from the bleak days of OS9. THere is now a wide array of encryption choices within Mac OS X. Let Gareth Poreus show you what they are.
* Cuts through the hype with a serious discussion of the security
vulnerabilities of the Mac OS X operating system
* Reveals techniques by which OS X can be “owned”
* Details procedures to defeat these techniques
* Offers a sober look at emerging threats and trends
