Description
In certain situations, software applications/programs need to execute with elevated privileges to perform required functions. However, if the privileges required for execution are at a higher level than the privileges assigned to organizational users invoking such applications/programs, those users are indirectly provided with greater privileges than assigned by the organizations.

Check Text (C-223850r958730_chk)

From the ISPF Command Shell enter: SETRopts list If the ACTIVE CLASSES list includes entries for the FACILITY, SURROGAT, and UNIXPRIV resource classes, this is not a finding. If either of the above resource classes is missing, this is a finding.

Fix Text (F-25511r515239_fix)

Define the ACTIVE CLASS Parameter in SETROPTS to include the FACILITY, SURROGAT and UNIXPRIV resource classes. EXAMPLES: SETR CLASSACT(FACILITY SURROGAT UNIXPRIV) SETR GENERIC(FACILITY SURROGAT UNIXPRIV) SETR GENCMD(FACILITY SURROGAT UNIXPRIV) SETR RACL(FACILITY SURROGAT UNIXPRIV)
