You need to establish access security for the DFM TP so that only authorized users and applications can remotely access it. To protect the DFM TP, you can:

• Limit which LUs can enter your z/OS® system
• Ensure that inbound requests to initiate conversations with the DFM TP contain security information such as user IDs and passwords
• Limit by user ID or group who can access the DFM TP
• Limit the administrators who can define and update information in the DFM TP profile
