What is a Firewall and How Does it Work?

A firewall is a security measure that protects a network from unauthorized access. It is a software or hardware device that blocks certain types of traffic from accessing the network.

A firewall will block all traffic from outside the network unless it is specifically allowed. It does this by inspecting each packet and comparing it to the rules in the filtering list. If there are no matching rules, then the packet will be dropped and not allowed onto the network.

A firewall can be used at home as well to protect your home network as well as your personal computer.
