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 --failed

Harden 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 .env files.

• 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Do not publish raw OpenClaw service ports directly to the internet.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.
