Which of the following is a method that employs geographical information for access control?

Geofencing is a method that uses geographical information to enforce access control based on the physical location of a device. This technology creates a virtual boundary around a specified geographical area, allowing organizations to define rules and policies to manage access to resources or applications based on whether the device is inside or outside that boundary.

For example, if a company uses geofencing to restrict access to sensitive data, employees would only be able to access this data when they are within a certain geographical location, such as the office or a secure environment. If they attempt to access the data from outside this defined area, access would be denied, thereby enhancing security by preventing unauthorized access based on location. This method is particularly useful for protecting sensitive information, as it leverages the location information provided by GPS or other geolocation technology.

Other options listed do not pertain to geographical access control. Virtual Mobile Infrastructure relates to mobile device management, Jailbreaking refers to removing software restrictions on devices, and DNS Over HTTPS is focused on encrypting DNS queries for privacy. None of these options utilize geographical information for controlling access to resources in the way that geofencing does.
