If authorization to the SYSTEM SPECIAL attribute is restricted to key systems personnel such as individuals responsible for continuing operations, Storage Management, and emergency recovery, this is not a finding.

If any users connected to sensitive system dataset HLQ (e.g., SYS1, SYS2, ETC) groups with the Group-SPECIAL are key systems personnel, such as individuals responsible for continuing operations, Storage Management, and emergency recovery, this is a finding.

Otherwise, Group-SPECIAL is allowed.
