Description

Add support for TCAP/MAP Signalling System 7 (SS7) protocols transported on the SIGTRAN stack:

IP / SCTP / MTP2 / MTP3 / SCCP / TCAP / MAP

This includes EVE logging and detection keywords.

Addressing schemes in this stack:
- IP address & SCTP port may not be useful for signatures
- Add support for Point Code (MTP3) & Subsystem Number (SCCP)
- Add support for Global Title (SCCP)

Fields useful as detection keywords:
- Message Type (TCAP)
- Operation Code (MAP)
- Other arguments specific to op codes (MAP)

Keep in mind the various protocol standards, ANSI MAP is different from GSM MAP (ITU).

  • TCAP: ITU-T Q.771-Q.775 or ANSI T1.114
