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.

Cryptography is now ubiquitous – moving beyond the traditional environments, such as government communications and banking systems, we see cryptographic techniques realized in Web browsers, e-mail programs, cell phones, manufacturing systems, embedded software, smart buildings, cars, and even medical implants. Today's designers need a comprehensive understanding of applied cryptography.
After an introduction to cryptography and data security, the authors explain the main techniques in modern cryptography, with chapters addressing stream ciphers, the Data Encryption Standard (DES) and 3DES, the Advanced Encryption Standard (AES), block ciphers, the RSA cryptosystem, public-key cryptosystems based on the discrete logarithm problem, elliptic-curve cryptography (ECC), digital signatures, hash functions, Message Authentication Codes (MACs), and methods for key establishment, including certificates and public-key infrastructure (PKI). Throughout the book, the authors focus on communicating the essentials and keeping the mathematics to a minimum, and they move quickly from explaining the foundations to describing practical implementations, including recent topics such as lightweight ciphers for RFIDs and mobile devices, and current key-length recommendations.

Drs. Pelton and Singh warn of the increasing risks of cybercrime and lay out a series of commonsense precautions to guard against individual security breaches. This guide clearly explains the technology at issue, the points of weakness and the best ways to proactively monitor and maintain the integrity of individual networks. Covering both the most common personal attacks of identity fraud, phishing, malware and breach of access as well as the larger threats against companies and governmental systems, the authors explain the vulnerabilities of the internet age. As more and more of life's transactions take place online, the average computer user and society at large have a lot to lose. All users can take steps to secure their information. Cybercrime is so subtle and hidden, people can ignore the threat until it is too late. Yet today about every three seconds a person is hit by some form of cyber attack out of the blue. Locking the “cyber-barn door” after a hacker has struck is way too late. Cyber security, cyber crime and cyber terrorism may seem to be intellectual crimes that don't really touch the average person, but the threat is real. Demystifying them is the most important step and this accessible explanation covers all the bases.
