SCTP Security Challenges
While SCTP provides several advantages over TCP and UDP for signaling transport, it also faces unique security challenges:
- Potential for new types of Denial of Service attacks due to multi-homing feature
- Risks associated with association hijacking and data injection
- Challenges in securing SCTP across different network domains
- Complexity in implementing end-to-end encryption for SCTP associations
- Integration of SCTP security with existing network security infrastructure
Understanding these security aspects is crucial for telecommunications professionals to implement robust security measures in SCTP-based signaling systems.
