RUSERS: Wrong Direction

This protocol anomaly is an RUSERS packet that flows in the wrong direction. RPC clients must send RPC calls; RPC servers must send RPC replies.

Extended Description

RPC call messages that originate from a server, and RPC reply messages originating from a client are anomalous. This could indicate a network misconfiguration, or that an attacker is attempting to spoof packets.
