Cyber security is the means by which individuals and organisations reduce the risk of becoming victims of cyber-attack.
Cyber security's core function is to protect the devices we all use (smartphones, laptops, tablets and computers), and the services we access - both online and at work - from theft or damage. It is also about preventing unauthorised access to the vast amounts of personal information we store on these devices, and online.
Cyber security is important because smartphones, computers and the internet are now a fundamental part of modern life, it is difficult to imagine how we would function without them. It is more important than ever to stake steps that can prevent cyber criminals getting hold of our accounts, data, and devices.
