Minutes 0-15: Initial Hardening

Start with the basics: update your packages, disable root SSH logins, and set up a basic firewall. But that's just the baseline. Most servers stop here—and most servers get breached.

Minutes 15-45: Deploying 1-SEC

This is where real security begins. Download the 1-SEC binary and enable the core modules.

Enabling WAF & Ransomware Defense

Activate the Injection Shield and Ransomware Interceptor. This protects your web services from exploits and your data from encryption in under 5 minutes.

Configuring Behavioral Monitoring

Turn on the Network Guardian with default behavioral heuristics. It will start learning your traffic patterns immediately, flagging any "odd" outbound requests that could indicate a breach.

Minutes 45-60: Verification & Monitoring

Run `1sec dashboard` to verify all modules are green. Use `1sec scan` to test your web endpoints. In just 60 minutes, your server has moved from "naked" to "fortified."
