PORTMAPPER: RPC Wrong Direction
This protocol anomaly detects a remote procedure call (RPC) packet that flows in the wrong direction, preventing Portmapper from performing the UDP port to RPC program numbers conversion. RPC clients must send RPC calls; RPC servers must send RPC replies.
Extended Description
RPC call messages originating from a server, and RPC reply messages originating from clients, are protocol anomalies and should be detected.
