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). Verify that access to the TADz Install 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 does not restrict UPDATEWRITE and/or ALTERgreater access to systems programming personnel. The TSS data set rules for the data sets does not specify that all (i.e., failures and successes) UPDATEWRITE and/or ALTERgreater access will be logged. If all of the above are untrue, this is not a finding. If any of the above is true, this is a finding.

The ISSO will ensure that updateWRITE and allocate/createor greater access to program product data sets is limited to systemsystems programmers only, and all updateWRITE and allocate/createor greater access is logged. Auditors should have readREAD access. The installing systems programmer will identify and document the product data sets and categorize them according to who will have updateWRITE and allocate/createor greater access and if required that all updateWRITE and allocate/createor greater access is logged. The installing systems programmer will identify if any additional groups have updateUPDATE access for specific data sets, and once documented, will work with the ISSO to ensure they are properly restricted to the Access Control Program (ACP) active on the system. Data sets to be protected will be: SYS2.TADZ SYS2.TADZ .V-.SHSIMOD1 (optional fully-qualified APF).

Title

Tivoli Asset Discovery for z/OS (TADz) Started Task name(s) must be properly identified / defined to the system ACP.

Check text

Refer to the following reports produced by the TSS Data Collection: - TSSCMDS.RPT(@ACIDS). Review each TADz STC/Batch ACID(s) for the following: ___ Is defined with Facility of STC and/or BATCH. ___ Is sourced to the INTRDR. If all of the abovefollowing attributes are truedefined, therethis is NOnot FINDINGa finding. If any of the above is untrueFACILITY(STC, this is a FINDING.BATCH) PASSWORD(xxxxxxxx,0) SOURCE(INTRDR) NOSUSPEND

Fix text

The TADz Systems Programmer and ISSO will ensure that the started task(s) for TADz is properly defined. Define the started task for TADz. Example: TSS CRE(TADZMON) DEPT(Dept) NAME('TADz STC') - FAC(STC) PASSWORD(password,0) - SOURCE(INTRDR) NOSUSPEND

Discussion

Tivoli Asset Discovery for z/OS (TADz) requires a started task(s) that will be restricted to certain resources, datasetsdata sets and other system functions. 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.

Refer to the following report produced by the TSS Data Collection: - TSSCMDS.RPT(#STC). Automated Analysis Refer to the following report produced by the TSS Data Collection: - PDI(ZTAD0032). Verify that the IBM Tivoli Asset Discovery for zOS (TADz) started task(s) is (are) defined in the TSS STC record. If this guidance is true, this is not a finding.

Fix text

The IBM Tivoli Asset Discovery for zOS (TADz) systemsystemsprogrammer programmer and the IAOISSO will ensure that a product's started task(s) is (are) properly identified and/or defined to the Systemsystem ACP. A unique ACID must be assigned for the IBM Tivoli Asset Discovery for zOS (TADz) started task(s) thruthrough a corresponding STC table entry. The following sample set of commands is shown here as a guideline: TSS ADD(STC) PROCNAME(TADZMON) ACID(TADZMON)

Discussion

Access to product resources should be restricted to only those individuals responsible for the application connectivity and who have a requirement to access these resources. Improper control of product resources could potentially compromise the operating system, ACP, and customer data.
