Security Considerations for Signaling Transport (SIGTRAN) Protocols

Telephony Signalling Transport over Stream Control Transmission Protocol (SCTP) Applicability Statement

“…Although some security needs overlap, any security solution should fulfill all the different parties' needs. See specific Security Considerations in each UAL Technical specification for details (for general security principles of SIGTRAN, see [RFC3788]). …”

Signaling System 7 (SS7) Message Transfer Part 2 (MTP2) - User Peer-to-Peer Adaptation Layer (M2PA)

“…Consult [RFC3788] for a discussion of security requirements and for guidance on the use of security protocols. Implementers of M2PA MUST follow the guidelines in [RFC3788].…”

“…Implementers of M2PA MUST follow the guidelines in [RFC3788]. The SCTP Payload Protocol Identifier is included in each SCTP Data chunk, to indicate which protocol the SCTP is carrying.…”

V5.2-User Adaptation Layer (V5UA)

“…The security considerations discussed for the 'Security Considerations for SIGTRAN Protocols' [5] document apply to this document. The SCTP Payload Protocol identifier value "6" SHOULD be included in each SCTP DATA chunk to indicate that the SCTP is carrying the V5UA protocol.…”
