Refer to the following report produced by the Datadataset Set and Resource Data Collection: - SENSITVE.RPT(VTARPT). Automated Analysis Refer to the following report produced by the Datadataset Set and Resource Data Collection: - PDI(ZVTA0000). Verify that the accesses to the CA VTAPE installation datadatasets sets are properly restricted. If the following guidance is true, this is not a finding. The ACF2 datadataset set rules for the datadatasets setsrestrict restricts READ access to all authorized users. The ACF2 datadataset set rules for the datadatasets setsrestrict restrictsWRITE UPDATE and/or ALTERgreater access to systems programming personnel. The ACF2 datadataset set rules for the datadatasets sets specify that all (i.e., failures and successes) UPDATEWRITE and/or ALTERgreater access areis logged.

Fix text

The ISSO will ensure that updateWRITE and/or allocategreater access to CA VTAPE installation datadatasets sets is limited to systemsystems programmers only, and all updateWRITE and/or allocategreater access is logged. ReadREAD access can be given to all authorized users. The installing systems programmer will identify and document the product datadatasets, sets and categorize them according to who will have updateWRITE and/or altergreater access, and if required, ensure that all updateWRITE and/or allocategreater access is logged. The installing systems programmer will identify if any additional groups have updateWRITE and/or altergreater access for specific data setsdatasets, and once documented, will work with the ISSO to ensure they are properly restricted to the Access Control Program (ACP) active on the system. DataDatasets sets to be protected will be: SYS2.VTAPE. SYS3.VTAPE. (dataDatasets sets that are not altered by product STCs, can be more specific.) The following commands are provided as a sample for implementing datadataset set controls: $KEY(SYS2) VTAPE.- UID(&ltsyspaudt>) R(A) W(L) A(L) E(A) VTAPE.- UID(&lttstcaudt>) R(A) W(L) A(L) E(A) VTAPE.- UID(&ltaudtaudt>) R(A) E(A) VTAPE.- UID(authorized users) R(A) E(A) VTAPE.- UID(&ltaudtaudt>) R(A) E(A) VTAPE.- UID(VTAPE STCs) R(A) E(A) $KEY(SYS3) VTAPE.- UID(&ltsyspaudt>) R(A) W(L) A(L) E(A) VTAPE.- UID(&lttstcaudt>) R(A) W(L) A(L) E(A) VTAPE.- UID(&ltaudtaudt>) R(A) E(A) VTAPE.- UID(authorized users) R(A) E(A) VTAPE.- UID(VTAPE STCs) R(A) E(A)

Discussion

CA VTAPE installation datadatasets sets have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to these datadatasets sets could result in violating the integrity of the base product, which could result in compromising the operating system or sensitive data.

Title

CA VTAPE STC data sets will be properly protected.

Check text

Refer to the following report produced by the Datadataset Set and Resource Data Collection: - SENSITVE.RPT(VTASTC). Automated Analysis Refer to the following report produced by the Datadataset Set and Resource Data Collection: - PDI(ZVTA0001). Verify that the accesses to the CA VTAPE STC datadatasets sets are properly restricted. If the following guidance is true, this is not a finding. ___ The ACF2 datadataset set rules for the datadatasets setsrestrict restricts READ access to auditors and authorized users. ___ The ACF2 datadataset set rules for the datadatasets setsrestrict restricts WRITE and/or greater access to systems programming personnel and Tape Management personnel. ___ The ACF2 datadataset set rules for the datadatasets setsrestrict restricts WRITE and/or greater access to the CA VTAPE's STC(s) and/or batch user(s).

Fix text

The ISSO will ensure that WRITE and/or greater access to CA VTAPE STC datadatasets sets is limited to systems programmers, tape management personnel, and/or CA VTAPE's STC(s) and/or batch user(s) only. ReadREAD access can be given to auditors and authorized users. The installing systems programmer will identify and document the product datadatasets, sets and categorize them according to who will have updateWRITE and/or altergreater access, and if required, ensure that all updateWRITE and/or allocategreater access is logged. The installing systems programmer will identify if any additional groups have updateWRITE and/or altergreater access for specific data setsdatasets, and once documented will work with the ISSO to ensure they are properly restricted to the ACP (Access Control Program) active on the system. DataDatasets sets to be protected will be: SYS3.VTAPE (dataDatasets sets that are altered by the product's STCs, this can be more specific.) The following commands are provided as a sample for implementing datadataset set controls: $KEY(SYS3) VTAPE.- UID(&ltsyspaudt>) R(A) W(A) A(A) E(A) VTAPE.- UID(&lttapeaudt>) R(A) W(A) A(A) E(A) VTAPE.- UID(&lttstcaudt>) R(A) W(A) A(A) E(A) VTAPE.- UID(VTAPE STCs) R(A) W(A) A(A) E(A) VTAPE.- UID(&ltaudtaudt>) R(A) E(A) VTAPE.- UID(authorize users) R(A) E(A)

Check text

Refer to the following report produced by the ACF2 Data Collection: - ACF2CMDS.RPT(ATTSTC). InsureVerify that the logonidslogonid(s) for the CA VTAPE started task(s) includesis (are) properly defined. If the following: attributes are defined, this is not a finding. STC NO-SMC

Fix text

The CA VTAPE systemsystems programmer and the IAOISSO 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 INSERT SVTS STC NO-SMC INSERT SVTSAS STC NO-SMC

Discussion

CA VTAPE requires a started task that will be restricted to certain resources, datasets, 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.
