Cyber Security
- is the application of technologies, processes and controls to protect systems, networks, programs,
devices and data from cyber attacks.
- Key Terms
- The topic of cyber security is sweeping the world by storm with some of the largest and most
advanced companies in the world falling victim to cyber-attacks in just the last 5 years.
- Against that backdrop, highly personal and sensitive
information such as social security numbers were recently
stolen in the Equifax hack, affecting over 145 million people.
- 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'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.
