Answer 2

Firewall

A firewall is protection technology that separates areas of a network from one another.

In practical terms, this generally means that it keeps an eye on all incoming and outgoing data packets.

It is a kind of digital gatekeeper and checks that these data packets are only sent in and out when they are actually permitted to. When doing so, the firewall works according to predefined rules to open, block and monitor the inbound and outbound access points (ports) as needed.
