Deploy MAM or MDM solutions with policies that prohibit the side-loading of apps, which may bypass security checks on the app.
Deploy MAM or MDM solutions with policies that prohibit the installation of apps from 3rd party (unofficial) app stores.
Use application threat intelligence data about potential abuse of location services associated with apps installed on COPE or BYOD devicesMobile Device User
Use Android Verify Apps feature to identify apps that may abuse location services.
When apps that require location services (e.g., map services) are not in use, use OS-provided settings to globally disable access to location services
When using untrusted apps that require locations services (e.g., map services), use OS-provided settings to revoke access to location services once the app is no longer in use.
Consider the use of devices that support iOS 14 or higher, in which users can decide whether or not applications have access to precision location of their device.
