2.3.8 Security Considerations

1. JWT Auth

• Validate tokens in the Socket.io handshake; reject unauthorized connections to prevent eavesdropping.

2. Rate Limiting

• Implement server-side logic to limit chat message frequency and protect from spam attacks.

3. Encryption

• For voice/video, WebRTC is generally encrypted (SRTP) by default.

• For text chat, messages travel over TLS-secured WebSockets, but you can also implement end-to-end encryption if required.

4. Logging & Monitoring

• Monitor socket events, track user connection durations, detect anomalies (rapid join/leave cycles, suspicious large data transmissions).
