From z/OS IBM Health Checker for TSS STIG
Part of ZB000001
Associated with IA controls: ECCD-2, ECAR-3, ECAR-2, ECCD-1, ECAR-1, DCSL-1
Associated with: CCI-001499
IBM Health Checker STC data sets have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to these data sets 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 Data Set and Resource Data Collection: - SENSITVE.RPT(HCKSTC) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZHCK0001) Verify that the accesses to the IBM Health Checker STC data sets are properly restricted. If the following guidance is true, this is not a finding. ___ The TSS data set rules for the data sets restricts READ access to auditors. ___ The TSS data set rules for the data sets restricts WRITE and/or greater access to systems programming personnel. ___ The TSS data set rules for the data sets restricts WRITE and/or greater access to the IBM Health Checker’s STC(s) and/or batch user(s).
The IAO will ensure that WRITE and/or greater access to IBM Health Checker STC data sets is limited to System Programmers and/or IBM Health Checker’s STC(s) and/or batch user(s) only. READ access can be given to auditors. 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. He will identify if any additional groups have WRITE and/or greater 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. The dataset to be protected can be found in the HZSPROC STC member in HZSPDATA DD statement. Data sets to be protected will be: SYS3.*.HZSPDATA The following commands are provided as a sample for implementing data set controls: TSS ADD(SYS3) DSN(SYS3) TSS PERMIT(syspaudt) DSN(SYS3.MMG.HZSPDATA) ACCESS(ALL) TSS PERMIT(Health Checker STCs) DSN(SYS3.MMG.HZSPDATA) ACCESS(ALL) TSS PERMIT(audtaudt) DSN(SYS3.MMG.HZSPDATA) ACCESS(READ)
