Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZAID0000). Verify that the accesses to the Compuware Abend-AID installation 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 restrictsrestrict READ access to all authorized users. ___ The TSS data set rules for the data sets restrictsrestrict WRITE and/or greater access to systems programming personnel. ___ The TSS data set rules for the data sets specify that all (i.e., failures and successes) WRITE and/or greater access is logged.

The ISSO will ensure that WRITE and/or greater access to Compuware Abend-AID installation data sets is limited to systems programmers only, and all WRITE and/or greater access is logged. READ access can be given to all authorized users. The installing systems programmer will identify and document the product data sets and categorize them according to who will have WRITE and/or greater access and if required that all WRITE and/or greater access is logged. The installing systems programmer will identify if any additional groups have WRITE and/or greater access for specific data sets and once documented he will work with the ISSO to see that they are properly restricted to the ACP (Access Control Program (ACP) active on the system. Data sets to be protected will be: SYS2.ABENDAID. SYS2A.ABENDAID. SYS3A.ABENDAID.

Fix text

The ISSO working with the systems programmer will ensure the Compuware Abend-AID Started Task(s) is properly identified and/or defined to the Systemsystem ACP. If the product requires a Started Task, verify that it is properly defined to the Systemsystem ACP with the proper attributes. Most installation manuals will indicate how the Started Task is identified and any additional attributes that must be specified. The following commands are provided as a sample for defining Started Task(s): TSS CREATE(BDCAS) TYPE(USER) - NAME('STC, Compuware Abend-AID') DEPT(xxxx) - FAC(STC,BATCH) PASS(xxxxxxxx,0) - SOURCE(INTRDR) NOSUSPEND TSS CREATE(TDCAS) TYPE(USER) - NAME('STC, Compuware Abend-AID for CICS') DEPT(xxxx) - FAC(STC,BATCH) PASS(xxxxxxxx,0) - SOURCE(INTRDR) NOSUSPEND TSS CREATE(AAVIEWER) TYPE(USER) - NAME('STC, Compuware Abend-AID Viewer') DEPT(xxxx) - FAC(STC,BATCH) PASS(xxxxxxxx,0) - SOURCE(INTRDR) NOSUSPEND

Discussion

Compuware Abend-AID requires a started task that will be restricted to certain resources, datasetsdata sets, and other system functions. ByDefining defining the started task as a userid to the system 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(ZAID0032). If the Compuware Abend-AID started task(s) is (are) defined in the TSS STC record, this is not a finding.

Fix text

The IAOISSO working with the systems programmer will ensure the Compuware Abend-AID Started Task(s) is properly identified and/or defined to the Systemsystem ACP. A unique ACID must be assigned for the Compuware Abend-AID started task(s) thruthrough a corresponding STC table entry. The following commands are provided as a sample for defining Started Task(s): TSS ADD(STC) PROCNAME(AAVIEWER) ACID(AAVIEWER) TSS ADD(STC) PROCNAME(BDCAS) ACID(BDCAS) TSS ADD(STC) PROCNAME(TDCAS) ACID(TDCAS)

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.
