Description
Fast Dump Restore (FDR) install have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to their datasets 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 dataset and Resource Data Collection: - SENSITVE.RPT(FDRRPT). Automated Analysis Refer to the following report produced by the dataset and Resource Data Collection: - PDI(ZFDR0000). Verify that access to the Fast Dump Restore (FDR) Install datasets is properly restricted. If the following guidance is true, this is not a finding. The ACF2 dataset rules for the datasets restrict WRITE and/or greater access to systems programming personnel. The ACF2 dataset rules for the datasets do not specify that all (i.e., failures and successes) WRITE and/or greater access will be logged.

Fix Text (F-25963r1141499_fix)

The ISSO will ensure that WRITE and/or greater access to Fast Dump Restore (FDR) install datasets is limited to systems programmers only, and all WRITE and/or greater access is logged. Auditors should have READ access. The installing systems programmer will identify and document the product datasets, 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 UPDATE access for specific datasets, and once documented he will work with the ISSO to ensure that they are properly restricted to the ACP (Access Control Program ) active on the system. Datasets to be protected will be: SYS2.FDR SYS2A.FDR The following commands are provided as a sample for implementing dataset controls: $KEY(SYS2) FDR.- UID(syspaudt) R(A) W(L) A(L) E(A) FDR.- UID(dasdaudt) R(A) W(L) A(L) E(A) FDR.- UID(dasbaudt) R(A) W(L) A(L) E(A) FDR.- UID(audtaudt) R(A) E(A) $KEY(SYS2A) FDR.- UID(syspaudt) R(A) W(L) A(L) E(A) FDR.- UID(dasdaudt) R(A) W(L) A(L) E(A) FDR.- UID(dasbaudt) R(A) W(L) A(L) E(A) FDR.- UID(audtaudt) R(A) E(A) $KEY(SYS3) FDR.- UID(syspaudt) R(A) W(L) A(L) E(A) FDR.- UID(dasdaudt) R(A) W(L) A(L) E(A) FDR.- UID(dasbaudt) R(A) W(L) A(L) E(A) FDR.- UID(audtaudt) R(A) E(A)
