Complete the following tasks to enable the security feature for each inbound service.

1. Set up transaction security through the mainframe with the security administrator.
2. Specify SECURITY=Y in the Inbound Services screen for each service you want to secure. When SECURITY=Y, the gateway attempts to start user programs with the username that initiated the request as reported by the remote system.

   If SECURITY=N, the gateway starts user programs using the gateway’s user ID (as controlled by the socket listener).
