What is Cyber Security?

According to the National Cyber Security Centre, cyber security is “how individuals and organisations reduce the risk of cyber attack”.

Cyber security protection involves all types of digital devices: smartphones, laptops, tablets, computers, webcams and routers, as well as smart home technology such as TVs, sound systems and home monitoring devices. It involves industrial systems used in the operating systems for cars, planes and road and rail infrastructure, to name just a few.

And, of course, a key function of cyber security is to prevent unauthorised access to data stored on any of these devices or online. Successful cyber-attacks can yield vast value – sometimes financial, sometimes by other measures – to a whole range of bad actors, ranging from lone petty criminals to nation state-owned entities.

The range of activities in effective cyber security management includes identifying threats, enabling protection policies and systems, detecting and responding to cyber security threats, and recovering data and systems in the event of a breach.

The industry depends on its practitioners developing a wide range of practical management skills as well as technical know-how. Learn more about the 16 core specialisms here.
