What is cybersecurity?
Protecting computers, networks and data from people who want to steal, break or misuse them. Every attack targets one of three things.
- Confidentiality
- Only the right people can see the data.
- Integrity
- Nobody changed it without permission.
- Availability
- It works when people need it.
