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.

Is a Cyber Security Certificate Worthwhile?

A cyber security certificate is often seen as proof that someone has either undertaken a course or gained a degree or experience in cyber security that modifies them to either give advice or be a lead in some type of cyber  governance policy.

This course can be true, but it is also important to check what the content of the cyber security course is or was,  who the provider was and whether or not the person holding the cyber security certificate has updated their knowledge since the course was completed.

It is a good thing to encourage everyone involved in any organisation or business to become aware of cyber security, and any type of training that enhances that knowledge or awareness is going to be helpful.

Issuing cyber security certificates do not necessarily mean a huge amount in their own right, except that a lot of people like certificates having completed courses.

It gives them a sense of achievement and accomplishment, and sometimes a sense of pride in the course they have done.


Any basic cyber security certificate should reflect a course that covers the basics of cyber security.

This may relate to specific IT systems or hardware or software configurations, or may simply be a more generalised introduction to the various threats that make up the main element of cyber security and how they can be dealt with.

A good cyber security course should include some moment of cyber insurance.

Whilst there is not expected to be an understanding of the technical elements of how insurance works, any cyber security system needs to have in place some element of insurance that can help do with a potential catastrophe of a huge data breach or similar.

A good cyber insurance policy provider will work with the organisation at the outset to help them identify the specific risks to their business or company, and will output in place structures that can help deal with the reality of cyber crime if it happens to take place.
