V17.2 Media

These requirements only apply to systems that host their own WebRTC media servers, such as Selective Forwarding Units (SFUs), Multipoint Control Units (MCUs), recording servers, or gateway servers. Media servers handle and distribute media streams, making their security critical to protect communication between peers. Safeguarding media streams is paramount in WebRTC applications to prevent eavesdropping, tampering, and denial-of-service attacks that could compromise user privacy and communication quality.

In particular, it is necessary to implement protections against flood attacks such as rate limiting, validating timestamps, using synchronized clocks to match real-time intervals, and managing buffers to prevent overflow and maintain proper timing. If packets for a particular media session arrive too quickly, excess packets should be dropped. It is also important to protect the system from malformed packets by implementing input validation, safely handling integer overflows, preventing buffer overflows, and employing other robust error-handling techniques.

Systems that rely solely on peer-to-peer media communication between web browsers, without the involvement of intermediate media servers, are excluded from these specific media-related security requirements.

This section refers to the use of Datagram Transport Layer Security (DTLS) in the context of WebRTC. A requirement related to having a documented policy for the management of cryptographic keys can be found in the "Cryptography" chapter. Information on approved cryptographic methods can be found either in the Cryptography Appendix of the ASVS or in documents such as NIST SP 800‑52 Rev. 2 or BSI TR‑02102‑2 (Version 2025‑01).
