Computer security, also known as cybersecurity or IT security, is about protecting computer systems, networks, and software from threats like data theft, unauthorized access, or damage.[1][2]

An example of a physical security measure: a metal lock on the back of a computer to stop someone from accessing it.

As people rely on computer more it has become important to protect the Internet and smart devices like smartphones and IoT devices. With information systems becoming more complex, securing them is a big challenge we face today, especially for areas like power grids, elections, and finance.[3][4] While digital tools like passwords and encryption are key, traditional physical security, like locks, still plays a role. Cybersecurity is a broad field and doesn’t fully overlap with other types of security.
