10-Point Hardening Checklist

Ensure no admin panels, debug interfaces, or management endpoints are accessible from the public internet. Use VPNs, SSH tunnels, or private networks.

Implement IP allowlisting for sensitive operations. Only trusted IPs should access admin functions or critical tools.

All endpoints must require authentication. No default credentials—force users to set strong passwords on first run.

Apply rate limiting to all API endpoints. Prevent brute force attacks and resource exhaustion.

Store secrets in environment variables or a vault. Never hardcode API keys, passwords, or tokens in code or configuration files.

Implement automatic credential rotation for API keys and service accounts. Have a breach response plan ready.

Validate and sanitize all user inputs before processing. Implement strict type checking, length limits, and content filtering.

Enable comprehensive logging for all agent actions, tool calls, and system events. Log to a secure, tamper-evident system.

Implement real-time monitoring of tool usage patterns, resource consumption, and anomalous behaviors. Set up alerts for suspicious activities.

Run agent tool execution in isolated environments (containers, VMs, or sandboxes). Limit resource access and implement escape prevention.

Document incident response procedures. Have a runbook for common scenarios: credential exposure, unusual activity, suspected breach.
