firewall

A firewall is a security system that controls the incoming and outgoing network traffic between your business and the internet


A firewall could be seen as the all-in-one security system to protect your house. It’s a bit like securing the perimeter with a good fence, then adding good door locks, intruder alarm, security camera and all the other parts to home security.

Unlike the house with only a few entry points, a computer network has thousands of entry points and all these need to be controlled. The firewall has the main purpose of controlling all these entry points, only allowing those who should have access get in. Having a firewall can help deter potential attackers as they see the extra layer of complex security and move onto find an unprotected network.
