Cyber security is how individuals and organisations reduce the risk 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.
The concept of Cybersecurity, over time, even motivated by the very notion of digital transformation, has been the target of different interpretations. It can be understood as the set of measures and actions necessary to prevent, monitor, detect, analyse and correct networks and information systems against the threats to which they are exposed, trying to maintain a desired security state and guarantee confidentiality, integrity, availability and non-repudiation of information, can, on the other hand, be defined as the feeling of security perceived by people when using the Internet and digital technologies.
It's 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 such a fundamental part of modern life, that it's difficult to imagine how we'd function without them. From online banking and shopping, to email and social media, it's more important than ever to stake steps that can prevent cyber criminals getting hold of our accounts, data, and devices.?
