Description
Transparent Data Migration Facility (TDMF) installation data sets have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to these data sets could result in violating the integrity of the base product which could result in compromising the operating system or sensitive data.

Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(TDMFRPT) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZTDM0000) Verify that the accesses to the Transparent Data Migration Facility (TDMF) installation data sets are properly restricted. If the following guidance is true, this is not a finding. ___ The ACF2 data set rules for the data sets restricts READ access to auditors. ___ The ACF2 data set rules for the data sets restricts WRITE and/or greater access to systems programming personnel. ___ The ACF2 data set rules for the data sets specify that all (i.e., failures and successes) WRITE and/or greater access is logged.

Fix Text (F-26013r1041265_fix)

The ISSO will ensure that The ISSO will ensure that WRITE and/or greater access to Transparent Data Migration Facility (TDMF) installation data 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 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 will work with the ISSO 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.TDMF. SYS3.TDMF. The following commands are provided as a sample for implementing data set controls: $KEY(SYS2) TDMF.- UID(<syspaudt>) R(A) W(L) A(L) E(A) TDMF.- UID(<tstcaudt>) R(A) W(L) A(L) E(A) TDMF.- UID(<audtaudt>) R(A) E(A) $KEY(SYS3) TDMF.- UID(<syspaudt>) R(A) W(L) A(L) E(A) TDMF.- UID(<tstcaudt>) R(A) W(L) A(L) E(A) TDMF.- UID(<audtaudt>) R(A) E(A)
