The listener can be configured with security. This way, privileged operations, such as saving configuration changes or stopping the listener, used from the Listener Control utility will require a password. Oracle Net Manager enables you to set an encrypted password.
To set a password for the listener:
In the navigator pane, expand Oracle Net Configuration > Local > Listeners.
Select a listener.
From the list in the right pane, select General Parameters.
Select the Authentication tab.
Choose Require a Password for Listener Operations.
Enter the password in the Password field, and re-enter it in the Confirm Password field.
