Facebook app presents OPSEC threat for Airmen Published Nov. 2, 2010 By Heidi Hunt 509th Bomb Wing Public Affairs WHITEMAN AIR FORCE BASE, Mo. -- Facebook recently launched a new application on its social network which allows users to view who and where a person has checked into. The application is called "Places I Checked Into" which is automatically activated on each users Facebook account until they disable it. Facebook users are advised to disable the application because of the risk associated with this feature according to Air Force Global Strike Command Logistic, Installations and Mission Support directorates. How it works When the user logs on from another network, the application uses the IP address and identifies where that person is. The application then posts the user's location status on the user's wall to include a description and map. Why it's a concern Users are inadvertently compromising their location and putting themselves at risk by drawing attention to their exact whereabouts. This application can potentially be used by terrorists to target military personnel, family and friends. How do I disable the application? Step 1: Click Account then Privacy Setting. On the first page that appears click 'Customise [sic] settings.' Step 2: Under Things I share heading, disable Include me in People here now after I check in by un-clicking the box. Step 3: In the same menu click on Places I check in to tab to only me by clicking on the drop down menu on the right, choosing Custom, then Only Me, then Save Settings. Step 4: To stop other users from posting your location on Facebook, under Things others share section click the Edit Settings tab to the right of Friends can check me in to places, then select the drop down men and choose disable, then click Ok. Step 5: Go back to Account, then Privacy Settings and under Applications and websites select edit your settings, which is highlighted in blue. Click the edit settings tab next to the Information accessible through your friends. Step 6: Then unclick the boxes and click Ok to save changes. By following these steps, Facebook users can disable the application and avoid letting other users know what location a person has checked in to. "Although most Airmen follow a routine, even in their personal lives, they establish a pattern without realizing they are doing so," said Cheri LeBlanc, 509th Bomb Wing information protection. "If individuals check their page at the same time every day, they could easily establish a pattern for others to follow and capitalize on."
