What is cybersecurity?

Cybersecurity is the practice of protecting networks, devices and data from damage, loss or unauthorized access. Just as physical security protects buildings and the people in them from various physical threats, cybersecurity safeguards digital technologies and their users from digital dangers.

Cybersecurity is a broad topic, covering many different disciplines, actions, threats and ideas. However, these parts come back to the same idea: protecting people’s digital lives and assets.
