Securing CICS

Use this information to plan and implement security across your CICS® systems.

CICS uses an external security manager (ESM), such as RACF®, to secure CICS systems, and the resources in those systems, against unauthorized access. This documentation assumes that the ESM used is RACF. Example configurations use RACF commands. If you use another ESM, the principles of security are the same but you must use your ESM documentation to find the equivalent configuration details and commands.

This documentation assumes that security is enabled. This is done by setting the SEC system initialization parameter to SEC=YES. For information, see SEC system initialization parameter.
