Free CompTIA Security+ SY0-701 Practice Question

The 'Somewhere you are' factor relates to the use of geographic location as part of the authentication process. Typically, this involves technologies such as GPS or IP address location services to verify the user's current physical location. This kind of authentication is particularly useful for enforcing location-based access policies, such as allowing access to a corporate network only from within a secure physical office or predefined safe geofenced areas. Other answers, 'Something you know', 'Something you have', and 'Something you are', refer respectively to knowledge factors like passwords, possession factors like smart cards or tokens, and inherence factors like biometrics, all of which are separate from the user's location.
