Computer Security (Second Edition) Dieter Gollmann Today, security is no longer only a topic of interest for specialists, but a concern for all end users, systems administrators, and software developers The development of new kinds of IT applications means that unique security threats continue to emerge. These new challenges may require novel solutions, and traditional security solutions can actually exacerbate the problem rather than solve it. Dieter Gollman's popular text continues to offer a comprehensive yet concise overview of the subject that will help the reader think about security at every level. Beginning with basic definitions and concepts and going on to outline the mechanisms as the heart of the computer system, this book covers security issues in networks, operating systems and databases, and shows how to evaluate and tackle security problems. Update throughout, the second edition includes brand new chapters on software security, authentication in distributed systems, new paradigms in access control, and mobility. Also included are brief introductions to security managements and cryptography. Computer Security is essential reading for undergraduate and postgraduate students on a variety of introductory and advanced security courses in computer science, engineering and related disciplines. Technical and project managers will also find that this book offers a great starting point for dealing with complex security challenges.
