Open Streaming Platform (OSP) exposes ingest, control-plane, and playback surfaces. Hardening must prioritize stream-key control, RTMP/HLS endpoint protection, and separation of admin/API components from media workers.
¶ 1) Harden ingest authentication and stream-key lifecycle
- Require unique per-channel stream keys for RTMP ingest.
- Rotate stream keys when stream operators or automation users change.
- Disable or delete unused ingest keys/channels.
- Alert on repeated invalid ingest attempts.
- Keep admin/API services on private network segments or VPN.
- Expose only required public playback/ingest endpoints.
- Restrict DB/Redis to internal interfaces.
- Enforce HTTPS for web/admin interfaces with HSTS.
- Store DB, Redis, and object-storage secrets outside repository.
- Use dedicated service accounts for media storage buckets/paths.
- Enforce retention and cleanup for temporary HLS segments.
- Encrypt archive backups and protect access logs.
¶ 4) Apply rate limits and abuse controls
- Set reverse-proxy rate limits for API and login routes.
- Cap concurrent ingest sessions per user/channel where supported.
- Apply upload and request-size limits for control APIs.
- Monitor transcoder queue depth and fail-closed behavior under overload.
