OpenBoard is primarily a local desktop whiteboard application, not a multi-tenant web service. Security hardening therefore focuses on endpoint security, file integrity, and controlled plugin/media content.
- Run OpenBoard on managed Linux user profiles with disk encryption.
- Enforce OS account lock/screen lock for classroom devices.
- Restrict local admin rights on shared teaching machines.
- Keep OpenBoard and OS packages updated from trusted repositories.
- Store board documents on restricted paths with regular backups.
- Enforce access control for shared network folders used by teachers.
- Validate imported media/PDF files before opening on shared systems.
- Disable unsafe auto-open behavior for external files.
- Restrict embedded web/browser components via firewall or DNS policy if not needed.
- Use outbound allow-lists on classroom endpoints.
- Block telemetry/update channels by policy only when mirrored update mechanism exists.
- Audit plugin additions on managed images.
