Description
BMC IOA User data sets, IOA Core and Repository, 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.

Verify that the accesses to the BMC IOA User data sets are properly restricted. If the following guidance is true, this is not a finding.

___ The TSS data set access authorizations restricts READ access to auditors.

___ The TSS data set access authorizations restricts WRITE and/or greater access to systems programming personnel.

___ The TSS data set access authorizations restricts WRITE and/or greater access to the BMC STCs and/or batch users.

___ The TSS data set access authorizations restricts UPDATE access to production control and scheduling personnel and the BMC users.

Fix Text (F-6816r2_fix)
The IAO will ensure that WRITE and/or greater access to BMC IOA User data sets are limited to System Programmers and/or BMC STCs and/or batch users only. UPDATE access can be given to production control and scheduling personnel and the BMC users. 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 update and alter access and if required that all update and allocate access is logged. He will identify if any additional groups have update and/or alter 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. (Note: The data sets and/or data set prefixes identified below are examples of a possible installation. The actual data sets and/or prefixes are determined when the product is actually installed on a system through the product’s installation guide and can be site specific.) Data sets to be protected will be: SYS3.IOA..IOAC. The following commands are provided as a sample for implementing data set controls: TSS PERMIT() DSN(SYS3.IOA..IOAC.) ACCESS(ALL) TSS PERMIT() DSN(SYS3.IOA..IOAC.) ACCESS(ALL) TSS PERMIT(BMC STCs) DSN(SYS3.IOA..IOAC.) ACCESS(ALL) TSS PERMIT() DSN(SYS3.IOA..IOAC.) ACCESS(U) TSS PERMIT() DSN(SYS3.IOA..IOAC.)
