OpenClaw Security Hardening
Use this skill to reduce exposure in self-hosted OpenClaw deployments before opening access to teammates or external networks.
Build a Threat Model First
Map the highest-risk assets and paths:
- Admin/API endpoints for OpenClaw
- Provider API keys and model credentials
- Prompt/response logs containing sensitive business data
- Host-level access (SSH, local admin accounts, remote desktop)
Prioritize controls that reduce credential theft, remote code execution blast radius, and data exfiltration.
Apply Baseline Host Hardening
- Keep OS and package dependencies patched on a regular cadence.
- Run OpenClaw as a dedicated non-admin user account.
- Enable full-disk encryption and secure boot features where available.
- Remove unnecessary services and block inbound ports by default.
- Lock down remote admin (key-only SSH, no password login, limited source CIDRs).
Example Linux baseline checks:
id openclaw
sudo ss -tulpn
sudo ufw status verbose
sudo systemctl --failedHarden Application Runtime
- Bind OpenClaw to localhost or private VLAN by default.
- Place a reverse proxy in front of OpenClaw for TLS, auth, and rate limits.
- Enforce authentication on every non-health endpoint.
- Disable debug/dev modes in persistent environments.
- Restrict outbound egress to only required providers (LLM API, telemetry sink, package mirror).
Example reverse proxy controls to enforce:
- TLS 1.2+ only
- strict transport security header
- request body size limits
- request timeout and upstream timeout guardrails
- per-IP and per-token rate limiting
Protect Secrets and Tokens
- Store secrets in a vault or platform secret manager, not committed
.envfiles. - Rotate provider and admin tokens on a fixed interval and after any incident.
- Scope tokens minimally (least privilege, per-service keys).
- Scan repos and deployment artifacts for leaked credentials before release.
Rotation checklist:
- Generate replacement key.
- Update runtime secret store.
- Restart or reload OpenClaw.
- Validate request success with new key.
- Revoke old key.
Segment Network Access
Use layered access patterns:
- Tier 1 (private): OpenClaw service port reachable only from app/proxy subnet.
- Tier 2 (operator): Admin plane reachable only from VPN/Tailscale/WireGuard.
- Tier 3 (public): Expose only hardened reverse proxy with strict ACLs.
Do not publish raw OpenClaw service ports directly to the internet.
Add Detection and Recovery Paths
- Centralize auth, error, and audit logs.
- Alert on brute-force attempts, token failures, and unusual outbound traffic.
- Capture immutable backup snapshots of configs and prompt data retention settings.
- Test rollback and restore procedures every release cycle.
Minimum operational runbook:
- service restart path
- key revocation path
- incident isolation path (network block + token disable)
- known-good rollback version
Validation Checklist
- All sensitive endpoints require auth and are unreachable without VPN or gateway policy.
- Secrets are absent from repo history and plaintext shared directories.
- Host firewall default deny is active for inbound traffic.
- TLS termination and rate limits are active at ingress.
- Rollback drill can restore service within target RTO.
