Discussion

CA Auditor installation 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.

Fix

The IAO ISSO will ensure that update and allocate access to CA Auditor installation data sets is limited to System systems Programmers programmers only, and all update and allocate access is logged. Read access can be given to auditors, security administrators, and/or CA Auditor’s Auditor's STCs and batch users. The installing Systems systems Programmer programmer will identify and document the product data sets and categorize them according to who will have update and alter access and if required that all update and allocate access is logged. He The installing systems programmer will identify if any additional groups have update and/or alter access for specific data sets, and once documented he will work with the IAO ISSO to ensure see that they are properly restricted to the ACP (Access Control Program) 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: $KEY(SYS2) EXAMINE.- UID(<syspaudt>) R(A) W(L) A(L) E(A) EXAMINE.- UID(<audtaudt>) R(A) E(A) EXAMINE.- UID(<secaaudt>) R(A) E(A) EXAMINE.- UID(EXAMMON) R(A) E(A) $KEY(SYS2A) EXAMINE.- UID(<syspaudt>) R(A) W(L) A(L) E(A) EXAMINE.- UID(<audtaudt>) R(A) E(A) EXAMINE.- UID(<secaaudt>) R(A) E(A) EXAMINE.- UID(EXAMMON) R(A) E(A)
