SS7 Security
Understand the security challenges, vulnerabilities, and protection strategies for Signaling System 7 (SS7) networks in telecommunications.
Signaling System 7 (SS7) is a critical protocol suite used in telecommunications networks worldwide. However, its design, which dates back to the 1970s, didn't anticipate today's security challenges. As a result, SS7 networks face several security issues that can potentially compromise user privacy, network integrity, and service availability.

Key security challenges in SS7 networks include:
- Lack of built-in authentication and encryption
- Implicit trust between network operators
- Exposure of subscriber information
- Potential for call interception and eavesdropping
- Vulnerability to location tracking and fraud
Addressing these security challenges is crucial for maintaining the integrity and trustworthiness of telecommunications networks that still rely on SS7 protocols.
