OPSEC, 'geo-tagging' and social networking Published Jan. 7, 2011 By Rob Sexton 20th Fighter Wing Public Affairs SHAW AIR FORCE BASE, S.C. -- As a newly trained alternate information assurance officer for my duty section, I suppose my brain is now extra-sensitive to this sort of information. So when I began to read the Army PowerPoint presentation attached to a recent email, I was blown away to learn how easy it is to pick potentially damaging (and outright dangerous) information from apparently innocent activities. The Internet not only has made the world a smaller place, but a much more dangerous place! For instance, do you know that simply using a 3G phone to take a picture in a public place makes it possible for a bystander to quickly and easily find out where you live?! I urge everyone, particularly those of you who use social networking websites, or even just post images online, to read and heed the above presentation.
