SIGTRAN Security Challenges
While SIGTRAN provides a robust framework for transporting SS7 signaling over IP networks, it also introduces new security challenges:
- Exposure of SS7 networks to IP-based attacks
- Potential for signaling message interception and manipulation
- Risks associated with the convergence of SS7 and IP networks
- Challenges in securing SIGTRAN across different network domains
- Complexity in implementing end-to-end encryption for SIGTRAN traffic
Understanding these security aspects is crucial for telecommunications professionals to implement robust security measures in SIGTRAN-based signaling networks.
