The Dictionary of Information Security provides complete and easy to read explanations of common security and infrastructure protection terms (quick refresher terms). Special attention is given to terms that most often prevent educated readers from understanding journal articles or books in cryptography, computer security, information systems, role-based access management and applied fields that build on those disciplines. Also included in the dictionary are terms that refer to computing forensics, malware attacks, privacy issues, system design, security auditing and vulnerability testing. Although it is difficult for an IT professional or an IT student to keep aware of the current terminology being practiced today, the Dictionary of Information Security presents cutting-edge information on the most recent terms in use in one concisely formatted volume. Similar to dictionaries for languages, statistics, epidemiology and other disciplines, this IT Security Dictionary is a reference tool that should become part of any professional and IT student's library. The Dictionary of Information Security is designed for a professional audience, composed of researchers and practitioners in industry. This dictionary is also suitable for students in computer science, engineering and information sciences.
