z/OS Planning for Multilevel Security and the Common Criteria

This document describes the z/OS® functions that can be used to provide multilevel security. Multilevel security is a security policy that allows the classification of data and users based on a system of hierarchical security levels combined with a system of non-hierarchical security categories. This document provides a high-level overview of multilevel security and security labels, and information about how to migrate a z/OS system to a multilevel-secure system. This document does not provide all the details that an administrator needs to configure or operate a system to take advantage of multilevel security, but it references other documents where you can find the details.
