The product's systems programmer will verify that any configuration/parameters that are required to control the security of the product are properly configured and syntactically correct. SeeRefer to the required parameters below: Parameter Options: VOLUME SECURITY = YES CHECK TARGET EMPTY = YES Session Options: Volume Security is not available. CHECKTarget|CHKTarget NOTENote: The ISSO will ensure that volume resource protection is defined to the ACP and access to volumes beis given to the appropiateappropriate personnel.

Title

Transparent Data Migration Facility (TDMF) installation data sets will be not properly protected.

Check text

Refer to the following report produced by the Datadataset Set and Resource Data Collection: - SENSITVE.RPT(TDMFRPT). Automated Analysis Refer to the following report produced by the Datadataset Set and Resource Data Collection: - PDI(ZTDM0000). Verify that the accesses to the Transparent Data Migration Facility (TDMF) 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 auditors. ___ The ACF2 datadataset set rules for the datadatasets setsrestrict restricts WRITE and/or greater access to systems programming personnel. ___ The ACF2 datadataset set rules for the datadatasets sets specify that all (i.e., failures and successes) WRITE and/or greater access is logged.

The ISSO will ensure that The ISSO will ensure that WRITE and/or greater access to Transparent Data Migration Facility (TDMF) installation datadatasets sets is limited to systems programmers only, and all WRITE and/or greater access is logged. READ access can be given to auditors. The installing systems programmer will identify and document the product datadatasets, sets and categorize them according to who will have WRITE and/or greater access, and if required, ensure 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 setsdatasets, and once documented will work with the ISSO to seeensure that they are properly restricted to the ACP (Access Control Program) active on the system. DataDatasets sets to be protected will be: SYS2.TDMF. SYS3.TDMF. The following commands are provided as a sample for implementing datadataset set controls: $KEY(SYS2) TDMF.- UID(&ltsyspaudt>) R(A) W(L) A(L) E(A) TDMF.- UID(&lttstcaudt>) R(A) W(L) A(L) E(A) TDMF.- UID(&ltaudtaudt>) R(A) E(A) $KEY(SYS3) TDMF.- UID(&ltsyspaudt>) R(A) W(L) A(L) E(A) TDMF.- UID(&lttstcaudt>) R(A) W(L) A(L) E(A) TDMF.- UID(&ltaudtaudt>) R(A) E(A)

Discussion

Transparent Data Migration Facility (TDMF) 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.
