Description
The TSOAUTH resource class controls sensitive privileges, such as OPER, ACCOUNT, CONSOLE, and PARMLIB. Several of these privileges offer the ability, or provide a facility, to modify sensitive operating system resources. Failure to properly control and restrict access to these privileges may result in the compromise of the operating system environment, ACP, and customer data.
