Designed to be used by acquiring organizations, system integrators, manufacturers, and Common Criteria testing/certification labs, the Common Criteria (CC) for IT Security Evaluation is a relatively new international standard. This standard provides a comprehensive methodology for specifying, implementing, and evaluating the security of IT products, systems, and networks. This book explains in detail how and why the CC methodology was developed, describes the CC methodology and how it is used throughout the life of a system, and illustrates how each of the four categories of users should employ the methodology as well as their different roles and responsibilities.
