Cyber security has become a well-known term in recent years. With most people spending a large part of their day online, communicating through media such as email and social media and conducting their banking and shopping online, its not surprising that risks come with the digitalisation of all your data. But what exactly is cyber security? What constitutes a cyber-attack? Who are the cyber criminals? And who is at risk?
Cyber security is essentially a new term for information security; the protection of vital information. Information security has, however, been around for decades prompting many to ask what is new about cyber security? In todays age, cyber security refers to more than simply protecting information. There is now an industrial scale of cyber espionnage. The only thing that is new about cyber security is that there is more information moving around faster in cyber space that there ever was when it could only be paper based, but it is still all about preventing people from accessing information they have no right to and using it for nefarious purposes.Think of it in terms of moving from handwriting to typewriter to telegraph to telephone, telefaxes and recording devices and now to cyber space. It is the volume and complexity that has increased, not the basic concept of information protection and espionnage for industrial and military purposes. But with the increased volume, there is also the possibility of causing more harm to more people. Cyber space has been militarised. There is a large rise in hacktivism (the use of computer hacking for political activism), with large swaths of cyber-crime and a dependence on the internet with the proliferation of devices.
