The Diameter protocol communication can be protected by using Transport Layer Security, TLS.
TLS Configuration
TLS requires a keystore file that is generated by using the Java standard command keytool. For further information about the keytool command, see the JDK product documentation.
Enter the keystore path and the keystore password in the Diameter Stack configuration.
From the Peer Table, in the Diameter Routing profile configuration select the TCP/TLS protocol for the peer with which you want to establish a secure connection.
TLS Configuration Properties
You can control the handling of unrecognized certificates by setting the Execution Context property mz.diameter.tls.accept_all.

Check the certificate. If you trust it, import it into the keystore by using the Java standard keytoolcommand. For further information, see the standard Java documentation.
