Check Text (C-55076r807788_chk)
For each load area, run a CREPORT 43 to check the nodes and access types for each node. For each node, issue DCMT D LINE. For each LINE type with a status of InSrv, inspect the access type for potential unauthorized connection types.

For TCP/IP, any line with access type SOCKET, issue DCMT D LINE <tcp-line-id>. If any terminals are of type LIST and status InSrv, check port number for a valid port. If the port number is unacceptable as defined in the PPSM CAL, this is a finding.

For each terminal with the type of LIST and InSrv, issue DCMT D PTE <pterm-id>. For each task and (possible PARM STRING which could pass a task) identified in the PTE display, issue DCMT D TASK <task-id>. If the task is IDMSJSRV and the associated program is RHDCNP3J, this is not a finding. If the task/program has not been authorized, this is a finding.

If other access types (e.g., VTAM, SVC, CCI) have been deemed nonsecure in the PPSM CAL, this is a finding.
Fix Text (F-55030r807789_fix)
For any pterm found to have nonsecure attributes (task, program, port), disable by issuing DCMT V PTE <pterm-id> OFF.

Using SYSGEN, remove offending lines, pterms, lterms, and/or port numbers and regenerate the system.
