Whitelist meaning and defininition

Whitelisting is a cybersecurity strategy under which a user can only take actions on their computer that an administrator has explicitly allowed in advance.

In essence, the user has access to only a limited set of functionality, and what they can access has been deemed safe by the administrator.
