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 ### What It Does LayerProtectionImplementationNetworkFirewall, SSH hardeningUFW, custom port (your choice), key-onlySystemAuto-updates, monitoringunattended-upgrades, auditdSecretsCredential managementCentralized .env, 600 permissionsMonitoringAudit logging, alertingKernel-level audit, multi-channel alerts ### Requirements OS: Ubuntu 20.04+ or Debian 11+ (Linux only) NOT supported: Windows (use WSL2), macOS Root access Existing SSH key authentication Alert channel (optional): Telegram, Discord, Slack, Email, or Webhook Custom SSH port of your choice (1024-65535) ### SSH Port: 22 → ${SSH_PORT} (your choice, 1024-65535) Auth: Keys only (no passwords) Root login: Disabled Max retries: 3 Fail2ban: Brute-force protection ### Firewall Default: Deny incoming Allow: Your chosen SSH port only ### Services CUPS (printing): Stopped & disabled Fail2ban: Intrusion detection enabled Auto-updates: Security patches automatic ### Monitoring Credential file access tracking SSH config change detection Privilege escalation alerts Daily security briefing ### Resource Usage ComponentRAMDiskAuditd~2 MB40 MB maxUFW~1 MBNegligibleScripts~5 MBNegligibleTotal<10 MB<50 MB ### Files scripts/install.sh - Main installation scripts/verify.sh - Verify installation scripts/rollback-ssh.sh - Emergency rollback scripts/critical-alert.sh - Telegram alerts scripts/daily-briefing.sh - Daily reports rules/audit.rules - Audit configuration ### Documentation See README.md for full documentation. ### License MIT - See LICENSE file ## Trust - Source: tencent - Verification: Indexed source record - Publisher: MarcusGraetsch - Version: 1.0.6 ## Source health - Status: healthy - Source download looks usable. - Yavira can redirect you to the upstream package for this source. - Health scope: source - Reason: direct_download_ok - Checked at: 2026-04-23T16:43:11.935Z - Expires at: 2026-04-30T16:43:11.935Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/vps-openclaw-security-hardening) - [Send to Agent page](https://openagent3.xyz/skills/vps-openclaw-security-hardening/agent) - [JSON manifest](https://openagent3.xyz/skills/vps-openclaw-security-hardening/agent.json) - [Markdown brief](https://openagent3.xyz/skills/vps-openclaw-security-hardening/agent.md) - [Download page](https://openagent3.xyz/downloads/vps-openclaw-security-hardening)
