Activating CA Top Secret Security

To use CA Top Secret to secure your region, you must activate it and CAIENF (both CAIENF and CICS must be active). You can use two methods to activate CA Top Secret security in a CICS region:

• Set the SEC security parameter in the DFHSIT to YES (see the section, SIT Security Parameter Settings, for details) or
• Set the FACMATRX and the CA Top Secret EXTSEC suboptions to YES. The facility can be shared by multiple CICS regions. If the FACMATRX suboption is specified, all regions with the facility would have CA Top Secret activated.

The FACMATRX(YES) suboption overrides the DFHSIT security parameter settings and uses the equivalent CA Top Secret FACILITY suboptions to implement security.
