The WebRTC Security Checklist

12 security gaps hiding in your WebRTC implementation. Most teams don't find them until their first audit.

Your WebRTC product works. Users connect, media flows, calls happen.

Then a security review asks: how are you rotating TURN credentials? Are you filtering ICE candidates? What happens if a peer sends a malformed data channel message?

If those questions make your team pause, this checklist will save you months of catch-up. Each item maps to a specific vulnerability, its real-world impact, and the fix.

WebRTC Security Checklist

12 decisions your implementation needs to get right

What's inside

12 security decisions. Each one is a gap that gets exploited in production.

Not theoretical risks. These are the patterns that show up in penetration tests, compliance audits, and incident postmortems.

  • The SRTP enforcement gap that leaves media streams readable on the wire - and the one-line fix that closes it
  • Why your TURN credentials are probably valid longer than they should be, and what attackers do with stale tokens
  • The ICE candidate leak that exposes private IP addresses to every peer in the session
  • DTLS certificate validation - the step most implementations skip because "it works without it"
  • Consent freshness checks that prevent session hijacking after the initial handshake completes
  • The getUserMedia permission patterns that survive browser updates and privacy policy audits
  • Plus 6 more covering signaling authentication, data channel input validation, CSP headers, recording consent, owasp integration, and opaqueOrigin isolation

Who it's for

Not a security course. A decision audit for your WebRTC stack.

Security-conscious developers

You're building WebRTC features and want to get security right the first time. The checklist catches the protocol-level gaps that code reviews miss.

Engineering leads facing audits

Your product is headed into a compliance review or a customer security questionnaire. The checklist maps WebRTC-specific risks so you don't get blindsided.

Teams inheriting WebRTC code

You didn't build it, but you're responsible for it now. The checklist gives you a structured way to assess what's there and what's missing.

WebRTC security isn't a feature you add later. It's a set of decisions you need to make explicitly - this checklist tells you which ones.
