Firewalls

Mesh network topology

Firewalls are software programs (sometimes hardwired into a device) that intercept and inspect all traffic to and from a protected network or device. Traffic that meets specified criteria that designates it as safe is passed through, whereas all other traffic is blocked. Every network and device can be assumed to have a firewall by default. Firewalls are the main obstacle that an intruder must overcome.
