Network Security: Firewall, IDS, Encryption

Think of your network like a medieval castle. Without security, the gates are widely

open. First, you need a firewall; that's your mode. It decides who gets

in and who stays out. Next, ideas. These are your guards

on watch tasks, spotting suspicious activity before it hits the door. And finally,

encryption. That's your secret code. Even if a thief steals your gold,

they can't use it.
