Cyber security research is one of the important areas in the computer science domain which also plays a major role in the life of almost every individual, enterprise, society and country, which this book illustrates. A large number of advanced security books focus on either cryptography or system security which covers both information and network security. However, there is hardly any books available for advanced-level students and research scholars in security research to systematically study how the major attacks are studied, modeled, planned and combated by the community. This book aims to fill this gap. This book provides focused content related to specific attacks or attack families. These dedicated discussions in the form of individual chapters covers the application or area specific aspects, while discussing the placement of defense solutions to combat the attacks. It includes eight high quality chapters from established security research groups worldwide, which address important attacks from theoretical (modeling) as well as practical aspects. Each chapter brings together comprehensive and structured information on an attack or an attack family. The authors present crisp detailing on the state of the art with quality illustration of defense mechanisms and open research problems. This book also covers various important attacks families such as insider threats, semantics social engineering attacks, distributed denial of service attacks, botnet based attacks, cyber physical malware based attacks, cross-vm attacks, and IoT covert channel attacks. This book will serve the interests of cyber security enthusiasts, undergraduates, post-graduates, researchers and professionals working in this field.

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.

"In order to combat the increasing complexity of cyber attacks, a new category of cyber defense called dynamic cyber defense has been the focus of a significant amount of work. Dynamic cyber defense mechanisms aim to protect networks by modifying their attributes in order to confuse would-be attackers. Currently, the majority of the existing mechanisms are purely theoretical and have been the subject of minimal performance analysis. There has also been almost no effort to perform comparative analysis of different techniques. As a result, there is a great need for a method of modeling different mechanisms within a single system in order to conduct comprehensive, comparative performance analysis. This work develops the framework of a system called Dynamic Virtual Terrain (DVT), which can be used for comparative analysis of dynamic cyber defense mechanisms under identical conditions. DVT models network topology using nodes, which represent members of a network, and access permissions, which describe the connectivity of the network. DVT also defines a generic dynamic cyber defense algorithm that can be extended in order to implement a hierarchy of techniques. An implementation of DVT is created in order to perform experiments with IP address hopping, port hopping, and dynamic firewall mechanisms in a cyber attack simulation environment. Attack scenarios are developed to evaluate the performance of the mechanisms under identical conditions, and the results of simulating these scenarios are used to analyze the performance of the implemented mechanisms."--Abstract.
