Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These attacks generally aim to access, change, or destroy sensitive information, disrupt normal business operations, or extort money from users through methods such as ransomware.

In today’s world, where everything is interconnected — from personal devices and online banking to large-scale corporate systems and government databases — a solid cyber defense is not merely a luxury; it’s a necessity for both organizations and individuals. Effective cybersecurity involves implementing multiple layers of protection across all digital assets, including hardware, software, and data.

It also requires constant monitoring, employee awareness, and rapid response strategies to detect and mitigate threats before they cause damage.
