What is cyber security?
Its core function is to defend the digital services and devices we rely on from online threats, which includes safeguarding the vast amounts of data and personal information stored locally or in the cloud. Cyber security also ensures that innovative and emerging technologies (such as AI) can deployed in a secure way, so the opportunities they present can be fully realised.
Why is cyber security important ?
Cyber security matters because most organisations in the UK rely on digital technology to function. It ensures the UK’s critical national infrastructure continue to operate in our increasingly connected world, and that governments can provide essential services.
Businesses that suffer a cyber attack or data breach can expect financial loss-es, lengthy service disruption, regulatory fines and reputational damage. Cyber security should therefore be a key part of every organisation’s operational resilience.
On an individual level, phones, smart devices, computers and the internet are now a fundamental part of modern life. Cyber security can prevent criminals from accessing our accounts and services, and helps us to navigate our online lives, safely and with confidence.
A shared responsibility
Whether you’re working for critical infrastructure making sure the lights stay on, or simply setting up your child’s phone, the UK’s cyber security is now a shared responsibility where everyone needs to play a part. Only then can we stay ahead of the cyber criminals and hostile states that seek to do us harm.
