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:

  • The nature and challenges of computer security
  • The relationship between policy and security
  • The role and application of cryptography
  • The mechanisms used to implement policies
  • Methodologies and technologies for assurance
  • 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.

Matt has always been a very knowledgeable person in the UNIX security environment and a very nice chap too. Here he proves once and for all that he spans the whole spectrum of security science (if any ever doubted it).

What can be said, is that he tends to focus more on the Science than the Art, but he does an excellent job of it.
