a) Refer to the following reports produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(SMPERPT) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ACP00140) Have the systems programmer for z/OS supply the following information: - The data set name and associated SREL for each SMP/E CSI utilized to maintain this system. - The data set name of all SMP/E TLIBs and DLIBs used for installation and production support. A comprehensive list of the SMP/E DDDEFs for all CSIs may be used if valid. ___ The ACP data set rules for system-level product installation libraries (e.g., SMP/E CSIs) allow inappropriate access. ___ The ACP data set rules for system-level product installation libraries (e.g., SMP/E CSIs) do not restrict UPDATE and/or ALTER access to only z/OS systems programming personnel. b) If all of the above are untrue, there is NO FINDING. c) If any of the above is true, or if these data sets cannot be identified due to a lack of requested information, this is a FINDING.

Fix text

Review access authorization to critical system files. Evaluate the impact of correcting the deficiency. Develop a plan of action and implement the changes as required to protect System-level product installation libraries, The IAO will ensure that update and allocate access to all system-level product execution libraries are limited to system programmers only.
