Description
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) b) If the GSO MAINT record values conform to the following requirements, there is NO FINDING. Specifies the logonid, program, and library combinations used for system maintenance functions. NOTE: For logonids that match environments described in records, no SMF logging records will be created. NOTE: Entries will be restricted to production storage management user accounts and programs. c) If there is any deviation from the above requirements in the GSO MAINT record values, this is a FINDING.
