Msrpc Base Palo Alto, Example: the application msrpc-base has a risk rating of 2 and thus should not be blocked by an application filter blocking risk level 5 applications > configure Looks like PaloAlto sees the initial traffic flow as MSRPC-Base and as the flow continues it recognizes it as MS-kms. Does anyone else feel that the application dependencies for MSRPC are incorrect? PA currently lists MSRPC as dependent on MS-DS-SMB and NETBIOS-SS.
