This handbook introduces the basic principles and fundamentals of cyber security towards establishing an understanding of how to protect computers from hackers and adversaries. The highly informative subject matter of this handbook, includes various concepts, models, and terminologies along with examples and illustrations to demonstrate substantial technical details of the field. It motivates the readers to exercise better protection and defense mechanisms to deal with attackers and mitigate the situation. This handbook also outlines some of the exciting areas of future research where the existing approaches can be implemented. Exponential increase in the use of computers as a means of storing and retrieving security-intensive information, requires placement of adequate security measures to safeguard the entire computing and communication scenario. With the advent of Internet and its underlying technologies, information security aspects are becoming a prime concern towards protecting the networks and the cyber ecosystem from variety of threats, which is illustrated in this handbook. This handbook primarily targets professionals in security, privacy and trust to use and improve the reliability of businesses in a distributed manner, as well as computer scientists and software developers, who are seeking to carry out research and develop software in information and cyber security. Researchers and advanced-level students in computer science will also benefit from this reference.

This book constitutes the refereed proceedings of the 5th International Conference on Mathematical Methods, Models, and Architectures for Computer Network Security, MMM-ACNS 2010, held in St. Petersburg, Russia in September 2010. The 16 revised full papers and 6 revised short papers presented together with 5 invited papers were carefully reviewed and selected from a total of 54 submissions. The papers are organized in topical sections on security modeling and covert channels, security policies and formal analysis of security properties, authentication, authorization, access control and public key cryptography, intrusion and malware detection, security of multi-agent systems and software protection, as well as. adaptive security, security analysis and virtualization.

This volume contains papers presented at the 3rd International Workshop on Mathematical Methods, Models and Architectures for Computer Network - curity (MMM-ACNS 2005) held in St. Petersburg, Russia, during September 25–27, 2005. The workshop was organized by the St. Petersburg Institute for Informatics and Automation of the Russian Academy of Sciences (SPIIRAS) in cooperation with Binghamton University (SUNY, USA). The 1st and the 2nd International Workshops on Mathematical Methods, Models and Architectures for Computer Network Security (MMM-ACNS 2001 and MMM-ACNS 2003), hosted by the St. Petersburg Institute for Informatics and Automation, demonstrated the keen interest of the international research community in the subject area. It was recognized that conducting a biannual series of such workshops in St. Petersburg stimulates fruitful exchanges between the di?erent schools of thought, facilitates the dissemination of new ideas and promotesthespiritofcooperationbetweenresearchersontheinternationalscale. MMM-ACNS 2005 provided an international forum for sharing original - search results and application experiences among specialists in fundamental and applied problems of computer network security. An important distinction of the workshop was its focus on mathematical aspects of information and computer network security addressing the ever-increasing demands for secure computing and highly dependable computer networks.

A comprehensive survey of computer network security concepts, methods, and practices. This authoritative volume provides an optimal description of the principles and applications of computer network security in particular, and cyberspace security in general. The book is thematically divided into three segments: Part I describes the operation and security conditions surrounding computer networks; Part II builds from there and exposes readers to the prevailing security situation based on a constant security threat; and Part III - the core - presents readers with most of the best practices and solutions currently in use. It is intended as both a teaching tool and reference. This broad-ranging text/reference comprehensively surveys computer network security concepts, methods, and practices and covers network security tools, policies, and administrative goals in an integrated manner. It is an essential security resource for undergraduate or graduate study, practitioners in networks, and professionals who develop and maintain secure computer network systems.

In its 4th edition, this book remains focused on increasing public awareness of the nature and motives of cyber vandalism and cybercriminals, the weaknesses inherent in cyberspace infrastructure, and the means available to protect ourselves and our society. This new edition aims to integrate security education and awareness with discussions of morality and ethics. The reader will gain an understanding of how the security of information in general and of computer networks in particular, on which our national critical infrastructure and, indeed, our lives depend, is based squarely on the individuals who build the hardware and design and develop the software that run the networks that store our vital information. Addressing security issues with ever-growing social networks are two new chapters: "Security of Mobile Systems" and "Security in the Cloud Infrastructure." Instructors considering this book for use in a course may request an examination copy here.

In the news on a daily basis are reports of lost or stolen computer data, hacker successes, identity thefts, virus and spyware problems, and network incursions of various kinds. Many people, especially nonprofessional administrators of home or small business networks, feel helpless. In this book, technical security expert Philip Alexander explains in layman's terms how to keep networks and individual computers safe from the bad guys. In presenting solutions to these problems and many others, the book is a lifeline to those who know their computer systems are vulnerable to smart thieves and hackers—not to mention tech-savvy kids or employees who are swapping music files, stealing software, or otherwise making a mockery of the word security. In his job protecting data and combating financial fraud, Philip Alexander knows well which power tools are required to keep hackers and thieves at bay. With his gift for putting technical solutions in everyday language, Alexander helps readers with home and/or small business networks protect their data, their identities, and their privacy using the latest techniques. In addition, readers will learn how to protect PDAs and smartphones, how to make hardware thefts more unlikely, how to sniff out scammers and the motives of offshore tech support personnel who ask too many questions, and how to keep personal information safer when shopping over the Internet or telephone.
