"This is an excellent text that should be read by every computer security professional and student." -Dick Kemmerer, University of California, Santa Barbara. "This is the most complete book on information security theory, technology, and practice that I have encountered anywhere!" -Marvin Schaefer, Former Chief Scientist, National Computer Security Center, NSA This highly anticipated book fully introduces the theory and practice of computer security. It is both a comprehensive text, explaining the most fundamental and pervasive aspects of the field, and a detailed reference filled with valuable information for even the most seasoned practitioner. In this one extraordinary volume the author incorporates concepts from computer systems, networks, human factors, and cryptography. In doing so, he effectively demonstrates that computer security is an art as well as a science. Computer Security: Art and Science includes detailed discussions on: bull;The nature and challenges of computer security bull;The relationship between policy and security bull;The role and application of cryptography bull;The mechanisms used to implement policies bull;Methodologies and technologies for assurance bull;Vulnerability analysis and intrusion detection Computer Security discusses different policy models, and presents mechanisms that can be used to enforce these policies. It concludes with examples that show how to apply the principles discussed in earlier sections, beginning with networks and moving on to systems, users, and programs. This important work is essential for anyone who needs to understand, implement, or maintain a secure network or computer system. 0201440997B10252002
