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 data sets could result in violating the integrity of the base product which could result in compromising the operating system or sensitive data.Information Assurance OfficerDCSL-1, ECAR-1, ECAR-2, ECCD-1, ECCD-2

a) Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(FDRRPT) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZFDR0000) b) Verify that access to the Fast Dump Restore (FDR) Install data sets are properly restricted. ___ The ACF2 data set rules for the data sets does not restrict UPDATE and/or ALTER access to systems programming personnel. ___ The ACF2 data set rules for the datasets does not specify that all (i.e., failures and successes) UPDATE and/or ALTER 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 IAO will ensure that update and allocate access to Fast Dump Restore (FDR) install data sets is limited to System Programmers only, and all update and allocate access is logged. Auditors should have READ access. The installing Systems Programmer will identify and document the product data sets and categorize them according to who will have update and alter access and if required that all update and allocate access is logged. He will identify if any additional groups have update access for specific data sets, and once documented he will work with the IAO 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.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)

Product configuration/parameters control the security and operational characteristics of products. If these parameter values are improperly specified, security and operational controls may be weakened. This exposure may threaten the availability of the product applications, and compromise the confidentiality of customer data.Systems ProgrammerECCD-1, ECCD-2
Checks: C-27990r1_chk

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 Data 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 a FINDING.

Fix: F-24349r1_fix

The systems programmer will verify that the security option ALLCALL is set to Yes. 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 data 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, ensure it is set to YES.
