CL/SuperSession Started Task name is not properly identified/defined to the system ACP.
Overview

| Description | ||||
| CL/SuperSession requires a started task that will be restricted to certain resources, data sets, and other system functions. Defining the started task as a userid to the system ACP allows the ACP to control the access and authorized users that require these capabilities. Failure to properly control these capabilities could compromise the operating system environment, ACP, and customer data. | ||||

Fix Text (F-26324r1145874_fix)
The Systems Programmer and ISSO will ensure that the started task for CL/SuperSession is properly defined.
Review all session manager security parameters and control options for compliance. Develop a plan of action and implement the changes as specified.
Define the started task userid KLS for CL/SuperSession.
Example:
TSS CRE(KLS) DEPT(Dept) NAME('CL/SuperSession STC') -
FAC(STC) MASTFAC(KLS) PASSWORD(password,0) -
SOURCE(INTRDR) NOSUSPEND
