Dynamic secrets are constantly generated and updated from messages exchanged between two communication users. When dynamic secrets are used as a complement to existing secure communication systems, a stolen key or password can be quickly and automatically reverted to its secret status without disrupting communication. "Dynamic Secrets in Communication Security" presents unique security properties and application studies for this technology. Password theft and key theft no longer pose serious security threats when parties frequently use dynamic secrets. This book also illustrates that a dynamic secret based security scheme guarantees impersonation attacks are detected even if an adversary steals a user's password or their key is lost. Practitioners and researchers working in network security or wireless communications will find this book a must-have reference. "Dynamic Secrets in Communication Security" is also a valuable secondary text for advanced-level students in computer science and electrical engineering.

Motivation for the Book This book seeks to establish the state of the art in the cyber situational awareness area and to set the course for future research. A multidisciplinary group of leading researchers from cyber security, cognitive science, and decision science areas elab orate on the fundamental challenges facing the research community and identify promising solution paths. Today, when a security incident occurs, the top three questions security admin istrators would ask are in essence: What has happened? Why did it happen? What should I do? Answers to the ?rst two questions form the core of Cyber Situational Awareness. Whether the last question can be satisfactorily answered is greatly de pendent upon the cyber situational awareness capability of an enterprise. A variety of computer and network security research topics (especially some sys tems security topics) belong to or touch the scope of Cyber Situational Awareness. However, the Cyber Situational Awareness capability of an enterprise is still very limited for several reasons: * Inaccurate and incomplete vulnerability analysis, intrusion detection, and foren sics. * Lack of capability to monitor certain microscopic system/attack behavior. * Limited capability to transform/fuse/distill information into cyber intelligence. * Limited capability to handle uncertainty. * Existing system designs are not very "friendly" to Cyber Situational Awareness.

Secure Broadcast Communication in Wired and Wireless Networks presents a set of fundamental protocols for building secure information distribution systems. Applications include wireless broadcast, IP multicast, sensor networks and webs, ad hoc networks, and satellite broadcast. This book presents and compares new techniques for basic operations including:
*key distribution for access control,
*source authentication of transmissions, and
*non-repudiation of streams.

This book discusses how to realize these operations both with high performance processors and resource constrained processors. It shows how to protect against adversaries who inject packets or eavesdrop. The focus is on functional descriptions rather than theoretical discussions. Protocols are presented as basic building blocks that can be combined with each other and traditional security protocols. The book illustrates these protocols in practice by presenting a real implementation that provides security for an ad hoc sensor network.

This book can serve as a textbook or supplementary reading in graduate level courses on security or networking, or can be used for self study.

The physical security of IT, network, and telecommunications assets is equally as important as cyber security. We justifiably fear the hacker, the virus writer and the cyber terrorist. But the disgruntled employee, the thief, the vandal, the corporate foe, and yes, the terrorist can easily cripple an organization by doing physical damage to IT assets. In many cases such damage can be far more difficult to recover from than a hack attack or malicious code incident. It does little good to have great computer security if wiring closets are easily accessible or individuals can readily walk into an office and sit down at a computer and gain access to systems and applications.
Even though the skill level required to hack systems and write viruses is becoming widespread, the skill required to wield an ax, hammer, or fire hose and do thousands of dollars in damage is even more common. Although many books cover computer security from one perspective or another, they do not thoroughly address physical security. This book shows organizations how to design and implement physical security plans. It provides practical, easy-to-understand and readily usable advice to help organizations to improve physical security for IT, network, and telecommunications assets.
* Expert advice on identifying physical security needs
* Guidance on how to design and implement security plans to prevent the physical destruction of, or tampering with computers, network equipment, and telecommunications systems
* Explanation of the processes for establishing a physical IT security function
* Step-by-step instructions on how to accomplish physical security objectives
* Illustrations of the major elements of a physical IT security plan
* Specific guidance on how to develop and document physical security methods and procedures

A new Computer Security textbook for a new generation of IT professionals. Unlike most other computer security textbooks available today, Introduction to Computer Security, 1e does NOT focus on the mathematical and computational foundations of security, and it does not assume an extensive background in computer science. Instead it looks at the systems, technology, management, and policy side of security, and offers students fundamental security concepts and a working knowledge of threats and countermeasures with "just-enough" background in computer science. The result is a presentation of the material that is accessible to students of all levels.

As computers are increasingly embedded, ubiquitous and wirelessly connected, security becomes imperative. This has led to the development of the notion of a 'trusted platform', the chief characteristic of which is the possession of a trusted hardware element which is able to check all or part of the software running on this platform. This enables parties to verify the software environment running on a remote trusted platform, and hence to have some trust that the data sent to that machine will be processed in accordance with agreed rules. This new text introduces recent technological developments in trusted computing, and surveys the various current approaches to providing trusted platforms. It also includes application examples based on recent and ongoing research. The core of the book is based on an open workshop on Trusted Computing, held at Royal Holloway, University of London, UK.
