This Security Technical Implementation Guide is published as a tool to improve the security of Department of Defense (DOD) information systems. The requirements are derived from the National Institute of Standards and Technology (NIST) 800-53 and related documents.

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.

The following steps are necessary for reviewing the FDR options: 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)' Select "I" on the FDR primary panel for INSTALL. Select "4" on the FDR installation options panel to select SETOPT. Verify the FDR Program Library Data Set on this panel specifies the following: Example: 'SYS2A.FDR.Vxxxx.LOADLIB'. Select "1" for SECURITY OPTIONS. Review the setting for ALLCALL. Automated Analysis Refer to the following report produced by the z/OS Data Collection: - PDI(ZFDR0040) If ALLCALL is set to YES, this is not a finding.

Fix: F-26152r1144823_fix

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

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.
Checks: C-26165r1144825_chk

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). Verify that access to the Fast Dump Restore (FDR) Install data sets are properly restricted. If the following guidance is true, this is not a finding. The RACF data set rules for the data sets restrict WRITE and/or greater access to systems programming personnel. The RACF data set rules for the data sets specify that all (i.e., failures and successes) WRITE and/or greater access will be logged.

Fix: F-26153r1145236_fix

The ISSO will ensure that WRITE and/or greater access to Fast Dump Restore (FDR) install data sets 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 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 UPDATE 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.FDR SYS2A.FDR The following commands are provided as a sample for implementing data set controls: ad 'sys2.fdr.**' uacc(none) owner(sys2) - audit(success(update) failures(read)) - data('Vendor DS Profile: fdr') pe 'sys2.fdr.**' id(syspaudt) acc(a) pe 'sys2.fdr.**' id(dasdaudt dasbaudt audtaudt) acc(r) ad 'sys2a.fdr.**' uacc(none) owner(sys2a) - audit(success(update) failures(read)) - data('fdr Vendor Datasets') pe 'sys2a.fdr.**' id(syspaudt) acc(a) pe 'sys2a.fdr.**' id(dasdaudt dasbaudt audtaudt) acc(r) ad 'sys3.fdr.**' uacc(none) owner(sys3) - audit(success(update) failures(read)) - data('Site Custom DS Profile: fdr') pe 'sys3.fdr.**' id(syspaudt) acc(a) pe 'sys3.fdr.**' id(dasdaudt dasbaudt audtaudt) acc(r) setr generic(dataset) refresh
