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.
a) Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(SVCRPT) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ACP00030) ___ The ACP data set rules for SYS1.SVCLIB allow inappropriate access. ___ The ACP data set rules for SYS1.SVCLIB do not restrict UPDATE and/or ALTER access to only z/OS systems programming personnel. ___ The ACP data set rules for SYS1.SVCLIB do not specify that all (i.e., failures and successes) UPDATE and/or ALTER access will be logged. b) If all of the above are untrue, there is NO FINDING. c) If any of the above is true, this is a FINDING.
The IAO will ensure that update and allocate access to SYS1.SVCLIB is limited to system programmers only and all update and allocate access is logged. Review access authorization to critical system files. 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.
Lavender hyperlinks in small type off to the right (of CSS

unambiguously about these things.
