Fix Recommendation

Ensure that the following Group function parameters appear and/or do not appear in ISFPARMS.

For each GROUP statement:
AUPDT(0)
AUTH will not be specified
CMDAUTH will not be specified
CMDLEV will not be specified
DSPAUTH will not be specified

The ISFPARMS GROUP statement defines user groups and their characteristics. Some of these characteristics include access authorization to SDSF functions and commands. Access to these functions and commands will be controlled using SAF resources. The use of the SAF interface is consistent with the DOD requirement to control all products within the operating system using the ACP. To ensure SAF security is always in effect, authorizations to SDSF functions and commands should not be defined in ISFPARMS DD statement in the SDSF JCL member.
