In today’s digital-first world, almost everything we do—banking, shopping, studying, working, and even socializing—happens online. This massive shift makes our data more vulnerable than ever. That’s where cyber security comes in.
Cyber security is no longer just an option; it is a necessity for individuals, businesses, governments, and every digital user. In this blog, we will explain what cyber security is and how it is used in the real world.
What Is Cyber Security?
Cyber security refers to the practice of protecting computers, networks, mobile devices, servers, and data from digital attacks. These attacks may include hacking, malware, ransomware, phishing, data breaches, and other cyber threats.
It involves a combination of technologies, processes, and best practices designed to keep systems secure from unauthorized access, misuse, or destruction.
