a) The following steps are necessary for reviewing the FDR options: 1) Issue the following command on the command line at option 6 in TSO to bring up the FDR ISPF dialog: EXEC 'SYS2.FDR.Vxxxx.CLIST(ABRALLOC)' 2) Select '"I'" on the FDR primary panel for INSTALL. 3) Select '"4'" on the FDR installation options panel to select SETOPT. 4) Verify the FDR Program Library Datadataset Set on this panel specifies the following: Example: 'SYS2A.FDR.Vxxxx.LOADLIB'. 5) Select '"1'" for SECURITY OPTIONS. 6) Review the setting for ALLCALL Automated Analysis Refer to the following report produced by the z/OS Data Collection: - PDI(ZFDR0040). b) If ALLCALL is set to YES, there is no finding. c) If ALLCALL is set to NO, this is not a finding.

The systems programmer will verify that the security option ALLCALL is set to YesYES. 1) Execute the FDR ISPF dialog by entering the following on the command line: EXEC 'SYS2.FDR.VXXXX.CLIST(ABRALLOC)' 2) Select '"I'" on the FDR PRIMARY OPTIONS MENU for INSTALL. 3) Select '"4'" on the INSTALLATION OPTIONS MENU to select SETOPT - SET INSTALLATION OPTIONS IN THE FDR GLOBAL OPTIONS TABLE. 4) Verify the FDR program library datadataset set on this panel is set to the current LOADLIB. Example: 'SYS2A.FDR.Vxxxx.LOADLIB'. 5) Select '"1'" to select SECURITY OPTIONS. 6) On the SET FDR GLOBAL SECURITY OPTIONS, review the ALLCALL setting, and ensure it is set to YES.

Title

Fast Dump Restore (FDR) install data sets are not properly protected.

Check text

a) Refer to the following report produced by the Datadataset Set and Resource Data Collection: - SENSITVE.RPT(FDRRPT). Automated Analysis Refer to the following report produced by the Datadataset Set and Resource Data Collection: - PDI(ZFDR0000). b) Verify that access to the Fast Dump Restore (FDR) Install datadatasets setsis are properly restricted. If the following guidance is true, this is not a finding. ___ The ACF2 datadataset set rules for the datadatasets sets does not restrict UPDATEWRITE and/or ALTERgreater access to systems programming personnel. ___ The ACF2 datadataset set rules for the datasets doesdo not specify that all (i.e., failures and successes) UPDATEWRITE and/or ALTERgreater access will be logged. c) If all of the above are untrue, there is no finding. d) If any of the above is true, this is a finding.

The ISSO will ensure that updateWRITE and/or allocategreater access to Fast Dump Restore (FDR) install datadatasets sets is limited to systems programmers only, and all updateWRITE and/or allocategreater access is logged. Auditors should have READ access. 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 updateUPDATE access for specific data setsdatasets, and once documented he 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.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)

Discussion

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 datadatasets sets could result in violating the integrity of the base product which could result in compromising the operating system or sensitive data.
