If you look at the Fitbit map you will see all those bases
But while it’s not new, it is a persistent, and ever-changing situation that the military has to contend with as some apps grow in popularity. In the summer of 2016, the US military banned players from installing Pokémon Go on government-issued cellphones, while various bases and stations around the country issued warnings to personnel to be mindful of their surroundings while playing. The military has also cautioned soldiers against using apps that tag one’s location, such as FourSquare.
In July 2017, the US Government Accountability Office released a report title “Internet of Things: Enhanced Assessments and Guidance Are Needed to Address Security Risks in DOD,” which found that even as internet-enabled devices are useful, the military needs to be mindful of the security risks that they pose, such as insider threats or intelligence gathering. Ultimately, the GAO recommended that the Department of Defense conduct security surveys to assess the risks that devices play, and develop policy accordingly.
The Strava map demonstrates the need for user awareness of the nature of the information that a device reveals to the outside world. While a single user might use the app for one particular activity, massive volumes of this information paint a revealing picture of a group’s activities. As the government and military work to evaluate and contend with potential security flaws, it’ll be up to the people using the app to be mindful of how they’re using their devices.
