Description
CL/SuperSession Install data sets provide the capability 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.

Fix Text (F-6666r1_fix)
The IAO will ensure that update and allocate access to CL/SuperSession install data sets are limited to system programmers only, and all update and allocate access is logged. 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 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. Data sets to be protected will be: sys2.omegamon. sys2.omegamon..tlsload sys2.omegamon..tlvload sys3.omegamon. sys3.omegamon.rlsload The following commands are provided as a sample for implementing dataset controls: TSS PERMIT(syspaudt) DSN(sys2.omegamon.)
