What is Access Control?
ISO 27001 access control is a security measure that limits who can view or use information. It’s like having a special key or password to get into a room or use a computer file. This helps keep important data safe from people who shouldn’t see it.
Examples
- Passwords: You need a password to log into your email. This password is a form of access control.
- Keycards: A keycard to enter an office building is another example. Only people with the right card can get in.
- Permissions: On a computer, you might have permission to read a document but not to change it. This controls what you can do with the file.
Context
Access control is a key part of information security. It makes sure that confidentiality, integrity, and availability of information are protected. It’s not just about stopping bad guys; it’s also about making sure people can’t accidentally mess up data. Organizations use this to meet rules and keep their info safe.
