Network Security
In the Army, we had “Force Protection.” Network security is your force protection in the digital world.
Description
Network security consists of the policies and practices adopted to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources.

- Segmentation: The compartmentalization of troops.
- VPN: The secure communications channel.
