The journey overview

In the video, we introduce you to Steve Rogers, who is an enterprise cloud and infrastructure architect at Coventry University.

Steve puts into context the development of network defence management over the past ten years – and highlights the role of firewalls.

Firewalls are an integral part of all computer network security solutions. Their basic function is to protect the local (trusted) network from an outside (untrusted) network, eg the internet. In doing so, the firewall monitors and analyses all incoming and outgoing traffic and reacts based on a predefined set of rules.

A firewall can be a very effective part of network security and in many cases, it is the first line of defence of a multi-layered approach. It can serve as part of a solution in implementing and enforcing the organisation’s security policy regarding traffic going to and from the internet.
