Seafile combines file synchronization, sharing, and web access. Security hardening should focus on TLS, trusted origins, and secret management in seahub_settings.py and service environment.
¶ 1) Enforce HTTPS and trusted origin controls
- Set
SERVICE_URL and FILE_SERVER_ROOT to HTTPS URLs.
- Configure
CSRF_TRUSTED_ORIGINS for the exact external domains.
- Set secure cookie behavior behind TLS (
SESSION_COOKIE_SECURE, CSRF_COOKIE_SECURE).
- Keep Seafile services behind a reverse proxy with HSTS.
¶ 2) Protect accounts and sharing policies
- Require strong password policy and MFA where supported.
- Restrict anonymous/public link defaults and enforce expiry.
- Disable open signup in business environments.
- Review stale external shares and revoke unnecessary links.
¶ 3) Secure database, cache, and object storage
- Keep DB and Redis internal-only.
- Rotate secrets and API credentials regularly.
- Protect object-storage credentials if using S3-compatible backend.
- Encrypt and test backup restores for metadata and libraries.
