Corporate Cyberwar chronicles the daily battle between technical criminals and law enforcement. As new and advanced ways to cheat and financially ruin companies are discovered, many authorities not only have to figure out ways to stop it, but they also have to create new laws in order to prosecute the perpetrators. This book addresses how businesses/corporations can protect themselves against this increasingly vicious attack. To help convey the importance of protection and awareness, Cyberwar explores two very important cases, WikiLeaks and Stuxnet. Businesses/corporations are given a better understanding of such similar attacks in the future. Corporate Cyberwar does not only focus on problems, it also provides solutions. There is a point by point explanation of how Crimeware, Bot Networks and DDoS (Distributed Denial of Service) take place, which helps businesses/corporations understand exactly what needs to be done in order to prevent the attacks. Cyberwar is not only for those with a moderate understanding of technology, it is also for those with limited understanding of this threat and its devastating effects.
Suddenly your Web server becomes unavailable. When you investigate, you realize that a flood of packets is surging into your network. You have just become one of the hundreds of thousands of victims of a denial-of-service attack, a pervasive and growing threat to the Internet. What do you do?
Internet Denial of Service sheds light on a complex and fascinating form of computer attack that impacts the confidentiality, integrity, and availability of millions of computers worldwide. It tells the network administrator, corporate CTO, incident responder, and student how DDoS attacks are prepared and executed, how to think about DDoS, and how to arrange computer and network defenses. It also provides a suite of actions that can be taken before, during, and after an attack.
Inside, you'll find comprehensive information on the following topics
How denial-of-service attacks are waged
How to improve your network's resilience to denial-of-service attacks
What to do when you are involved in a denial-of-service attack
The laws that apply to these attacks and their implications
How often denial-of-service attacks occur, how strong they are, and the kinds of damage they can cause
Real examples of denial-of-service attacks as experienced by the attacker, victim, and unwitting accomplices
The authors' extensive experience in handling denial-of-service attacks and researching defense approaches is laid out clearly in practical, detailed terms.

Penetration testing is a growing field but there has yet to be a definitive resource that instructs ethical hackers on how to perform a penetration test with the ethics and responsibilities of testing in mind. Penetration Testing and Network Defense offers detailed steps on how to emulate an outside attacker in order to assess the security of a network.
Unlike other books on hacking, this book is specifically geared towards penetration testing. It includes important information about liability issues and ethics as well as procedures and documentation. Using popular open-source and commercial applications, the book shows you how to perform a penetration test on an organization’s network, from creating a test plan to performing social engineering and host reconnaissance to performing simulated attacks on both wired and wireless networks.
Penetration Testing and Network Defense also goes a step further than other books on hacking, as it demonstrates how to detect an attack on a live network. By detailing the method of an attack and how to spot an attack on your network, this book better prepares you to guard against hackers. You will learn how to configure, record, and thwart these attacks and how to harden a system to protect it against future internal and external attacks.
Full of real-world examples and step-by-step procedures, this book is both an enjoyable read and full of practical advice that will help you assess network security and develop a plan for locking down sensitive data and company resources.
“This book goes to great lengths to explain the various testing approaches that are used today and gives excellent insight into how a responsible penetration testing specialist executes his trade.”

The Internet, as well as other telecommunication networks and information systems, have become an integrated part of our daily lives, and our dependency upon their underlying infrastructure is ever-increasing. Unfortunately, as our dependency has grown, so have hostile attacks on the cyber infrastructure by network predators. The lack of security as a core element in the initial design of these information systems has made common desktop software, infrastructure services, and information networks increasingly vulnerable to continuous and innovative breakers of security. Worms, viruses, and spam are examples of attacks that cost the global economy billions of dollars in lost productivity. Sophisticated distributed denial of service (DDoS) attacks that use thousands of web robots (bots) on the Internet and telecommunications networks are on the rise. The ramifications of these attacks are clear: the potential for a devastating largescale network failure, service interruption, or the total unavailability of service. Yet many security programs are based solely on reactive measures, such as the patching of software or the detection of attacks that have already occurred, instead of proactive measures that prevent attacks in the first place. Most of the network security configurations are performed manually and require experts to monitor, tune security devices, and recover from attacks. On the other hand, attacks are getting more sophisticated and highly automated, which gives the attackers an advantage in this technology race. A key contribution of this book is that it provides an integrated view and a comprehensive framework of the various issues relating to cyber infrastructure protection. It covers not only strategy and policy issues, but it also covers social, legal, and technical aspects of cyber security as well. We strongly recommend this book for policymakers and researchers so that they may stay abreast of the latest research and develop a greater understanding of cyber security issues.
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.
