Traffic-Associated DCE/RPC Rules

Most DCE/RPC preprocessor rules trigger against anomalies and evasion techniques detected in SMB, connection-oriented DCE/RPC, or connectionless DCE/RPC traffic. The following table identifies the rules that you can enable for each type of traffic.

Table 1. Traffic-Associated DCE/RPC Rules

Traffic

Preprocessor Rule GID:SID

SMB

133:2 through 133:26, and 133:48 through 133:59

Connection-Oriented DCE/RPC

133:27 through 133:39

Detect Connectionless DCE/RPC
