Vulnerability discussion

The system-wide options control the default settings for determining how the ACP will function when handling requests for access to the operating system environment, ACP, and customer data. The ACP provides the ability to set a number of these fields at the subsystem level. If no setting is found, the system-wide defaults will be used. The improper setting of any one of these fields, individually or in combination with another, can compromise the security of the processing environment. In addition, failure to establish standardized settings for the ACP control options introduces the possibility of exposure during a migration process or contingency plan activation.

a) Refer to the following report produced by the ACF2 Data Collection: - ACF2CMDS.RPT(ACFGSO) Automated Analysis requiring Additional Analysis Refer to the following report produced by the ACF2 Data Collection: - PDI(ACF0380) b) Compare the GSO PPGM record values with the programs: Check the SENSITIVE UTILITY CONTROLS Table is located in the Z/OS Addendum. c) If all applicable programs or their generic equivalent referenced in (b) above are represented by GSO PPGM record values, there is NO FINDING. d) If any applicable program referenced in (b) above is not represented by a GSO PPGM record value, this is a FINDING.

Fix text

The IAO will ensure that the PPGM GSO value indicates protected programs that are only executed by privileged users. Check the SENSITIVE UTILITY CONTROLS Table in the zOS STIG Addendum. Define protected programs that can only be executed by privileged users. PGM MASK(pgm mask1, ...,pgm-mask255) Example: SET C(GSO) INSERT PPGM PGM-MASK() F ACF2,REFRESH(PPGM)
