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).

Resources
  • All: ITU-T Q.700–Q.849 Series for SS7
  • TCAP: ITU-T Q.771-Q.775 or ANSI T1.114
  • MAP: 3GPP TS 29.002 or 3GPP2 X.S0004

Suricata's SCTP support is currently rather minimal. Is that enough for your use case or are you also planning improvements to SCTP?

We are planning to extend support and at the least at session tracking.
