Cybersecurity is the practice of protecting computers, networks, and data from attack.

Think of your house. You lock the doors. You might have an alarm system. You don’t leave your valuables on the front lawn. Cybersecurity is the same, but for digital systems. It’s about preventing bad people from getting in, and limiting the damage if they do.

Cybersecurity is not one thing. It’s many things. Network security protects data in transit. Application security finds bugs in software. Endpoint security protects laptops and phones. Identity management makes sure only the right people have access.

Every company needs cybersecurity. Banks, hospitals, governments, small businesses. Hackers are getting smarter. The defenders have to get smarter too. That’s why cybersecurity jobs are growing so fast.
