Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(ADTRPT). Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZADT0000). Verify that the accesses to the CA Auditor installation data sets are properly restricted. If the following guidance is true, this is not a finding. ___ The TSS data set rules for the data sets restrictsrestrict READ access to auditors, security administrators, and/or CA Auditor's STCs and batch users. ___ The TSS data set rules for the data sets restrictsrestrict UPDATEWRITE and/or ALLgreater access to systems programming personnel. ___ The TSS data set rules for the data sets specify that all (i.e., failures and successes) UPDATEWRITE and/or ALLgreater access are logged.

The ISSO will ensure that updateWRITE and/or allocategreater access to CA Auditor installation data sets is limited to systems programmers only, and all updateWRITE and/or allocategreater access is logged. ReadREAD access can be given to auditors, security administrators, and/or CA Auditor's STCs and batch users. The installing systems programmer will identify and document the product data sets and categorize them according to who will have updateWRITE and/or altergreater access and if required that all updateWRITE and/or allocategreater access is logged. The installing systems programmer will identify if any additional groups have updateWRITE and/or altergreater access for specific data sets, and once documented will work with the ISSO to ensure they are properly restricted to the ACP (Access Control Program (ACP) active on the system. Data sets to be protected will be: SYS2.EXAMINE SYS2A.EXAMINE The following commands are provided as a sample for implementing data set controls: TSS PERMIT(&ltsyspaudt>) DSN(SYS2.EXAMINE.) ACCESS(R) TSS PERMIT(&ltsyspaudt>) DSN(SYS2.EXAMINE.) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(&ltaudtaudt>) DSN(SYS2.EXAMINE.) ACCESS(R) TSS PERMIT(&ltsecaaudt>) DSN(SYS2.EXAMINE.)

Discussion

CA Auditor User data sets have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to these data sets could result in violating the integrity of the base product which could result in compromising the operating system or sensitive data.
