2. Why do you need network security?

There are many reasons why network security is important. These include:

Data loss

Every business has data that it must keep safe: customer information, staff data, financial records, supplier details etc.

Most individuals also have data that is vitally important to them, such as family photos, music collections or even that piece of homework that still needs to be handed in.

Organisations and individuals need to ensure that they protect their data by ensuring that their computers and the network is secure.

Unauthorised data change

Someone changing data in your name can cause no end of problems.

If someone were to gain access to your social media accounts and start posting comments and photos under your name - imagine the embarrassment and upset that could arise.

Malware called 'ransomware' is another example of unauthorised data change. Ransomware tries to encrypt your data files so they cannot be used unless payment is made to unlock them.
