Description
Specific PPT designated program modules possess significant security bypass capabilities. Unauthorized access could result in the compromise of the operating system environment, ACP, and customer data. Satisfies: SRG-OS-000080-GPOS-00048, SRG-OS-000259-GPOS-00100, SRG-OS-000324-GPOS-00125

Check Text ( C-25323r514639_chk )
Review program entries in the IBM Program Properties Table (PPT). You may use a third-party product to examine these entries however, to determine program entries issue the following command from an ISPF command line:
TSO ISRDDN LOAD IEFSDPPT
Press Enter.

For each module identified in the "eyecatcher" if all of the following are untrue, this is not a finding.

If any of the following is true, this is a finding.

-The ACP data set rules for libraries that contain PPT modules do not restrict WRITE or greater access to only z/OS systems programming personnel.
-The ACP data set rules for libraries that contain PPT modules do not specify that all WRITE or greater access will be logged.
Fix Text (F-25311r514640_fix)
Configure the WRITE or greater access to libraries containing PPT modules to be limited to system programmers only and all WRITE or greater access is logged.
