- PDI(ZISF0040)

Ensure the following Group Parameters are specified or not specified in the GROUP statements defined in the ISFPARMS members. If the following guidance is true, this is not a finding.

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
NAME a value will be specified for the NAME

Fix Text (F-26175r520362_fix)
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 NAME a value will be specified for the NAME 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.
