What is a Computer Network Security System?

Most people who have any type of computer probably understand at some level the basics of how they work, and probably understand what computer network security means in a very general sense.

Having a general understanding of computer security generally is obviously a good thing, but it is also important that people understand that there is a lot more to computer security and simply configuring the proper hardware and software.

A good computer network security system will depend to a large extent on the nature and size of the home or business. An individual home simply running one or two PCs  or tablets will need a computer network security system as much as a large multinational, but obviously different in terms of size and scope.

The first line of defence for any type of computer network security system is to make sure that boundary firewalls and Internet gateways are properly configured and enforced. This may sound a bit technical, but in fact it’s fairly straightforward for most people.


Any new hardware or software is going to need to be configured, and there is likely to be technical help available either from the manufacturer or from the ISP to help you configure it properly. Setting up proper firewalls can involve things like changing default passwords and making sure that the firewall is switched on at all times.

It is worth thinking of the basics of firewalls and internet gateways as being the front door into your system.

The ISPs will have a number of their own security systems in place that you should be to rely on, and some will offer additional software by way of either parental controls, secure shopping, virus protection etc.

One other thing that is likely to need to be addressed when setting up a computer network security system is that of who has access to it.

There is a lot of good advice around about how best to help children access the internet without them becoming secretive or isolated, and that principle can be expanded to include anyone who has access to the IT system.

A computer network security system is about who has access to it, and making sure that those people who have access, are comfortable using it, and are happy to ask for help or seek advice when needed.
