Fix Recommendation

The ISSO will ensure that WRITE and/or greater access to BMC IOA User data sets are limited to systems 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 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.

(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:

ad 'SYS3.IOA.*.IOAC.**' uacc(none) owner(SYS3) -
audit(failures(read)) -
data('BMC IOA User DS')

pe 'SYS3.IOA.*.IOAC.**' id(<syspaudt> <tstcaudt> BMC STCs) acc(a)
pe 'SYS3.IOA.*.IOAC.**' id(<bmcuser> <pcspaudt>) acc(u)
pe 'SYS3.IOA.*.IOAC.**' id(<audtaudt>) acc(r)

Automated Analysis
Refer to the following report produced by the Data Set and Resource Data Collection:

- PDI(ZIOA0002).

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 RACF data set access authorizations restricts READ access to auditors.

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

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

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

The RACF data set access authorizations specify UACC(NONE) and NOWARNING.
