RTP Security Challenges
While RTP provides essential functionality for real-time media delivery, it also faces several security challenges:
- Lack of built-in encryption in the base RTP specification
- Potential for eavesdropping and media interception in unsecured networks
- Vulnerability to replay attacks and stream manipulation
- Challenges in key management and distribution for secure RTP (SRTP)
- Balancing security measures with low-latency requirements of real-time communications
Understanding these security aspects is crucial for telecommunications professionals to implement robust security measures in RTP-based communication systems.
