Do a full factory reset with sanitization

You can use the U.S. DoD 5220-22M 7-pass scheme to erase data from a sensor, and clear disk space.

This process erases ALL data inside the sensor in accordance with the guidelines suggested in the NIST Special Publication 800-88 rev 1. All data and configurations (e.g., network and console password settings) are permanently deleted. The installed N2OS version remains the same.

Important: This procedure will cause the system to lose all its data and configurations. The networking configuration will be reset to factory settings.

Open a shell console.
Enter the command:
```
n2os-fullfactoryreset -iknowwhatimdoing
```
The system reboots with a factory setup.
Do the basic configuration again.
