Firewall

A firewall is software or hardware which helps to protect your company’s IT network by screening and blocking hackers, viruses or worms that try to infect your computer over the internet.

You should have a hardware firewall to protect your network and a software firewall on each individual computer to help prevent the spread of a virus in your network if one of the computer becomes infected.

Most Windows operating systems have a firewall built in and turned on by default.
