Diameter Security Challenges
While Diameter was designed to address many of the security shortcomings of its predecessor SS7, it still faces several security challenges:
- Potential for information disclosure and privacy breaches
- Vulnerabilities in roaming scenarios and inter-operator connections
- Risks associated with legacy SS7 interworking
- Challenges in implementing end-to-end encryption
- Emerging threats in 5G networks leveraging Diameter
Understanding these security aspects is crucial for telecommunications professionals to implement robust security measures in Diameter-based networks.
