Auditors should have read access.
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 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.TADZ
SYS2.TADZ .V-.SHSIMOD1
SYS3.TADZ
The following commands are provided as a sample for implementing dataset controls:
$KEY(SYS2)

a) Refer to the following report produced by the Data Set and Resource Data Collection:
- SENSITVE.RPT(TADZRPT)
Automated Analysis
Refer to the following report produced by the Data Set and Resource Data Collection:
- PDI(ZTAD0000)
b) Verify that access to the TADz Install data sets are properly restricted.
___ The ACF2 data set rules for the data sets does not restrict UPDATE and/or ALTER access to systems programming personnel.
___ The ACF2 data set rules for the data sets does not specify that all (i.e., failures and successes) UPDATE and/or ALTER access will be logged.
c) If all of the above are untrue, there is NO FINDING.
d) If any of the above is true, this is a FINDING.ZB000001<GroupDescription></GroupDescription>ZTADA001Tivoli Asset Discovery for zOS (TADz) STC and/or batch data sets are not properly protected.<VulnDiscussion>Tivoli Asset Discovery for zOS (TADz) STC data sets provide the capability to use privileged functions and/or have access to sensitive data.

Grant read access to any scheduling products that are in use.
Grant read access to auditors at the ISSO’s discretion.
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. Identify if any additional groups have update access for specific data sets, and assure that they are properly restricted to the ACP (Access Control Program) active on the system.

For all (TADz) STC and/or batch data sets:
If the UPDATE or greater access is restricted to systems programming personnel and the product STC(s) and/or batch job(s) this is not a finding.
If any job scheduling products are in use and access is restricted to READ this is not a finding.
If auditors have READ access this is not a finding.

By defining the started task as a userid to the system Access Control Program (ACP), it allows the ACP to control the access and authorized users that require these capabilities. Failure to properly control these capabilities, could compromise of the operating system environment, ACP, and customer data.</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></IAControls>DPMS Target Tivoli Asset Discovery for z/OS [TADz]DISADPMS TargetTivoli Asset Discovery for z/OS [TADz]1858CCI-000764The TADz system programmer and the ISSO will ensure that a product's Started Task(s) is properly identified / defined to the System ACP.
If the product requires a Started Task, verify that it is properly defined to the System ACP with the proper attributes.
Most installation manuals will indicate how the Started Task is identified and any additional attributes that must be specified.
Example:
SET LID
CHANGE TADZMON STCRefer to the following report produced by the ACF2 Data Collection:
- ACF2CMDS.RPT(LOGONIDS)
Ensure the following field is completed for each STC logonid for the product:
STC
Ensure the following field is completed for each Batch logonid for the product:
JOB
If the logonids specified in (b) and/or (c) have all the required field is completed, this is not a FINDING.
If the logonids specified in (b) and/or (c) do not have the above field completed, this is a FINDING.
