Context-based access control

Context-based access control is a way to make sure the right people have access to the right information at the right time. It is like having a gatekeeper who checks to see if someone is allowed to enter a certain room. In this case, the gatekeeper is a computer that looks at different factors (known as "context") to decide whether someone should have access to something. For example, the computer might look at the person's location or the time of day to see if they are allowed to read a certain document or access a certain website. If it decides the person should not have access, it will keep them out.
