Read 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 update and alter access and if required that all update and allocate access is logged. He 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 to 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)

Verify that the accesses to the CA Auditor installation data sets are properly restricted.
___ The ACF2 data set rules for the data sets restricts READ access to auditors, security administrators, and/or CA Auditor’s STCs and batch users.
___ The ACF2 data set rules for the data sets restricts UPDATE and/or ALTER access to systems programming personnel.
___ The ACF2 data set rules for the data sets specify that all (i.e., failures and successes) UPDATE and/or ALTER access are logged.ZB000020<GroupDescription></GroupDescription>ZADTA020CA Auditor resources are not properly defined and protected.<VulnDiscussion>CA Auditor can run with sensitive system privileges, and potentially can circumvent system controls. Failure to properly control access to product resources could result in the compromise of the operating system environment, and compromise the confidentiality of customer data. Many utilities assign resource controls that can be granted to system programmers only in greater than read authority. Resources are also granted to certain non systems personnel with read only authority.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Information Assurance Officer</Responsibility><Responsibility>Systems Programmer</Responsibility><IAControls>ECCD-1, ECCD-2</IAControls>DPMS Target CA Auditor for zOSDISA FSODPMS TargetCA Auditor for zOS2016CCI-000035CCI-002234The IOA will verify that the LTDMMAIN resource in the PROGRAM resource class is restricted to system programmers, auditors, and security personnel.
The ACF2 rules for the resource specify a default access of NONE. There are ACF2 rules defined and only system programmers, auditors, and security personnel have access.
