The IAO will ensure that update and allocate/create access to program product data sets is limited to System Programmers only, and all update and allocate/create access is logged. 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 allocate/create access and if required that all update and allocate/create 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 (optional fully-qualified APF). SYS3.TADZ The following commands are provided as a sample for implementing dataset controls: TSS PERMIT(syspaudt) DSN(SYS2.TADZ.) ACCESS(R) TSS PERMIT(syspaudt) DSN(SYS2.TADZ.)

The IAO will ensure that update and alter access to Tivoli Asset Discovery for zOS (TADz) STC and/or batch data sets are limited to system programmers and TADz STC and/or batch jobs only. Read access may be granted to auditors at the IAOs discretion. 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.

Tivoli Asset Discovery for z/OS (TADz) requires a started task(s) that will be restricted to certain resources, datasets 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.Information Assurance OfficerSystems ProgrammerECCD-1, ECCD-2

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 above are true, there is NO FINDING. If any of the above is untrue, this is a FINDING.

Fix: F-70741r2_fix

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)

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.

Fix: F-184r1_fix

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