This data set is automatically APF-authorized, contains system SVCs, and may also contain I/O appendages. Unauthorized access could result in the compromise of the operating system environment, ACP, and customer data.
Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(SVCRPT) Automated Analysis Review the following report produced by the Data Set and Resource Data Collection: - PDI(ACP00030) ___ Ensure that the ACP data set rules for SYS1.SVCLIB are limited to only appropriate authorized access. ___ Ensure that the ACP data set rules for SYS1.SVCLIB restrict UPDATE and/or ALTER access to only z/OS systems programming personnel. ___ Ensure that the ACP data set rules for SYS1.SVCLIB specify that all (i.e., failures and successes) UPDATE and/or ALTER access will be logged.
The IAO must ensure that update and allocate access to SYS1.SVCLIB is limited to system programmers only and all update and allocate access is logged and reviewed. Periodic reviews of access authorization to critical system files must be performed. Evaluate the impact of correcting the deficiency. Develop a plan of action and implement the changes for SYS1.SVCLIB. SYS1.SVCLIB contains SVCs and I/O appendages as such: they are very powerful and will be strictly controlled to avoid compromising system integrity.
