acceptedz/OS CA Auditor for RACF Security Technical Implementation GuideThis Security Technical Implementation Guide is published as a tool to improve the security of Department of Defense (DOD) information systems.

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 alter access is logged. The installing systems programmer will identify if any additional groups have update and/or alter 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) 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:

SRG-OS-000018<GroupDescription></GroupDescription>ZADTR020CA 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 systems 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></Responsibility><IAControls></IAControls>DPMS Target zOS CA Auditor for RACFDISADPMS TargetzOS CA Auditor for RACF4141V-17947SV-32209CCI-000213The ISSO will verify that the LTDMMAIN resource in the PROGRAM resource class is restricted to sytem programmers, auditors, and security personnel.
The RACF rules for the LTDMMAIN resource specify a default access of NONE and no RACF rules that allow access to the LTDMMAIN resource.
Example:

The RACF rules for the LTDMMAIN resource is restricted access to systems programmers, auditors, and security personnel with access of READ. All RACF rules are defined with UACC(NONE).
