DSA RealmWLScr Not Discarding Message From Peer Not In Whitelist Foreign Peer List {22477} (Doc ID 2811381.1)

Last updated on OCTOBER 01, 2021

Applies to:

Oracle Communications Diameter Signaling Router (DSR) - Version DSR 8.4.0 and later
Information in this document applies to any platform.

Symptoms

Diameter Signaling Router (DSR)-Diameter Custom Application (DCA)-Diameter Security Application (DSA): 
The Origin-Realm of the ingress diameter message is configured as Foreign network’s Realm but the Peer from which the diameter message is received is not configured in the AllowList Foreign Peer List. However, the message is not classified as "vulnerable".

We have tried Security_Countermeasure_Config.Origin_Realm_and_Destination_Realm_whitelist_screening_RealmWLScr.Continue_If_Vulnerable=Yes
              and Security_Countermeasure_Config.Origin_Realm_and_Destination_Realm_whitelist_screening_RealmWLScr.Continue_If_Vulnerable=No (current configuration),

and both result in the message passing through the DSR and not being discarded.
