VPS Security Hardening for OpenClaw

Production-ready security hardening for AI agent deployments on VPS.

⚠️ CRITICAL WARNINGS

DO NOT run OpenClaw on servers/machines with sensitive personal data. Use a dedicated machine (VPS, bare-metal, or on-premise server dedicated to OpenClaw).

Supported OS: Ubuntu 20.04+, Debian 11+. Not for Windows (use WSL2) or macOS.

⚠️ Choose Your SSH Port First

You must choose a custom SSH port (1024-65535) before installing. This makes you conscious of the security decision.

# Choose your port (example: 4848)
export SSH_PORT=4848

# Install
cd ~/.openclaw/skills/vps-openclaw-security-hardening
sudo ./scripts/install.sh

# Verify
./scripts/verify.sh

# Test SSH (new terminal)
ssh -p ${SSH_PORT} root@your-vps-ip
