ICCP: Unsupported TPDU Code
This signature detects an unsupported TPDU code. OSI Transport Class 0 (TP0) disallows the use of the Disconnect Confirm (DC), Expedited Data (ED), Acknowledge (AK), Expedited Acknowledgement (EA), and Reject (RJ) TPDUs. If such a code is received, it can possibly be a data injection or denial of service attack; it is likely that the attacked implementation would generate a Disconnect Request (DR), thereby terminating the connection.
