`; do not rely only on the signaling connection. 5. Add expiration, audience, filename, and nonce claims to media grants. Use HMAC-SHA-256 or an authenticated token format rather than MD5. 6. Apply per-IP and per-account rate limits, maximum concurrent WebRTC sessions, stream timeouts, file-size limits, and bandwidth quotas. 7. Reject unauthenticated Socket.IO connections before allocating `RTCPeerConnection` resources. 8.
