    This IBM Redpaper introduces the z/OS UNIX security model and implementation to MVS knowledgeable and security-minded users. It does not address in detail all the wealth of specific security features available in z/OS UNIX, but rather the base principles of operation and the mechanisms implementation with setup recommendations.

    We assume that the user already has a knowledge of the most commonly used IBM Resource Access Control Facility (RACF) setups and commands. However, we do not provide detailed procedures and explanations about the use of these commands.
