From z/OS ACF2 STIG
Part of ACF0280
Associated with IA controls: DCCS-1, DCCS-2
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 Refer to the following report produced by the ACF2 Data Collection: - PDI(ACF0280) b) If the GSO BACKUP record values conform to the following requirements, there is NO FINDING. Example: CPUID() PRISPACE(5) SECSPACE(5) STRING(S ACFBKUP) TIME(00:01) WORKUNIT(VIO) c) If there is any deviation from the above requirements in the GSO BACKUP record values, this is a FINDING.
The IAO will ensure that the BACKUP GSO value specifies a time field and Time(00:00 ) is not specified unless the database is shared and backed up on another system. CPUID() PRISPACE(5) SECSPACE(5) STRING(S ACFBKUP) TIME(00:01) WORKUNIT(VIO) Example: SET C(GSO) INSERT BACKUP CPUID() PRISPACE(5) SECSPACE(5) STRING(S ACFBKUP) TIME(00:01) WORKUNIT(VIO) F ACF2,REFRESH(BACKUP)
