The SRG considers the individual user or operative when using location-based apps. The SRG requires that any app using GPS and location-based services must not forward the user's location to an external resource unless the user explicitly acknowledges that this is taking place and knows where the data is going. When sensor data is either recorded locally or sent to a remote server, the potential exists for an adversary to obtain sensitive information that could be used to harm the user or compromise information systems. In particular, when location data is forwarded, the user may be physically targeted. User safety and mission assurance risks are mitigated when sensor data is only collected or forwarded when expressly authorized by the user.
