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

ℹ️ Check
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 TSS data set rules for the data sets does not restrict UPDATE and/or ALL access to systems programming personnel. ___ The TSS data set rules for the datasets does not specify that all (i.e., failures and successes) UPDATE and/or ALL 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.

✔️ Fix
The ISSO will ensure that update and/or ALL access to Fast Dump Restore (FDR) install data sets is limited to systems programmers only, and all update and/or ALL access is logged. All other FDR users can 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/or ALL access and if required that all update and/or ALL access is logged. The installing systems programmer will identify if any additional groups have update and/or ALL 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 dataset controls: TSS PERMIT(syspaudt) DSN(SYS2.FDR.) ACCESS(R) TSS PERMIT(syspaudt) DSN(SYS2.FDR.) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<fdrusers>) DSN(SYS2.FDR.) ACCESS(R) TSS PERMIT(syspaudt) DSN(SYS2A.FDR.) ACCESS(R) TSS PERMIT(syspaudt) DSN(SYS2A.FDR.) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<fdrusers>) DSN(SYS2A.FDR.) ACCESS(R)
