Description
Quest NC-Pass 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.

ℹ️ Check
Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(NCPASSTC). Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZNCP0001). Verify that the accesses to the Quest NC-Pass 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 restrict READ access to auditors. The TSS data set rules for the data sets restrict UPDATE access to domain level security administrators. The TSS data set rules for the data sets restrict WRITE and/or greater access to systems programming personnel. The TSS data set rules for the data sets restrict WRITE and/or greater access to the Quest NC-Pass's STC(s) and/or batch user(s).

✔️ Fix
The ISSO will ensure that WRITE and/or greater access to Quest NC-Pass STC data sets is limited to systems programmers and/or Quest NC-Pass's STC(s) and/or batch user(s) only. UPDATE access can be given to domain level security administrators. 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. The installing systems programmer will identify if any additional groups have WRITE and/or greater access for specific data sets, and once documented will work with the ISSO to ensure they are properly restricted to the Access Control Program (ACP) active on the system. Data sets to be protected will be: SYS3.NCPASS..PASSCAF SYS3.NCPASS..PASSVSDD The following commands are provided as a sample for implementing data set controls: TSS PERMIT(<syspaudt>) DSN(SYS3.NCPASS..PASSCAF) ACCESS(ALL) TSS PERMIT(<tstcaudt>) DSN(SYS3.NCPASS..PASSCAF) ACCESS(ALL) TSS PERMIT(NCASS STCs) DSN(SYS3.NCPASS..PASSCAF) ACCESS(ALL) TSS PERMIT(<secaaudt>) DSN(SYS3.NCPASS..PASSCAF) ACCESS(U) TSS PERMIT(<audtaudt>) DSN(SYS3.NCPASS..PASSCAF) ACCESS(R) TSS PERMIT(<syspaudt>) DSN(SYS3.NCPASS..PASSVSDD) ACCESS(ALL) TSS PERMIT(<tstcaudt>) DSN(SYS3.NCPASS..PASSVSDD) ACCESS(ALL) TSS PERMIT(NCASS STCs) DSN(SYS3.NCPASS..PASSVSDD) ACCESS(ALL) TSS PERMIT(<secaaudt>) DSN(SYS3.NCPASS..PASSVSDD) ACCESS(U) TSS PERMIT(<audtaudt>) DSN(SYS3.NCPASS..PASSVSDD) ACCESS(R)
