>Control Description
Prohibit [Selection (one or more): the use of devices possessing ⚙organization-defined environmental sensing capabilities in ⚙organization-defined facilities, areas, or systems; the remote activation of environmental sensing capabilities on organizational systems or system components with the following exceptions: ⚙organization-defined exceptions where remote activation of sensors is allowed]; and
Provide an explicit indication of sensor use to ⚙organization-defined group of users.
>DoD Impact Level Requirements
No specific parameter values or requirements for this impact level.
>Discussion
Sensor capability and data applies to types of systems or system components characterized as mobile devices, such as cellular telephones, smart phones, and tablets. Mobile devices often include sensors that can collect and record data regarding the environment where the system is in use. Sensors that are embedded within mobile devices include microphones, cameras, Global Positioning System (GPS) mechanisms, and accelerometers.
While the sensors on mobiles devices provide an important function, if activated covertly, such devices can potentially provide a means for adversaries to learn valuable information about individuals and organizations. For example, remotely activating the GPS function on a mobile device could provide an adversary with the ability to track the movements of an individual. Organizations may prohibit individuals from bringing cellular telephones or digital cameras into certain designated facilities or controlled areas within facilities where classified information is stored or sensitive conversations are taking place.
