OPSEC
Operations Security
Operations Security is the process of identifying, controlling, and protecting information that could give an adversary insight into friendly military plans, operations, or capabilities.
Operations Security (OPSEC) is a systematic method for identifying what information about friendly activities could be exploited by an adversary, and then taking measures to deny that information. The concept extends far beyond classified documents to encompass any observable pattern or indicator, troop movements, supply buildups, communications patterns, even social media posts by service members, that could reveal military intentions or capabilities.
OPSEC gained prominence during the Vietnam War when intelligence analysts discovered that North Vietnamese forces were anticipating U.S. operations by observing unclassified indicators like changes in dining hall menus, increased radio traffic, and movements of medical equipment. The formal OPSEC process involves five steps: identifying critical information, analyzing threats, analyzing vulnerabilities, assessing risks, and applying countermeasures.
In the modern era, OPSEC challenges have multiplied with the proliferation of smartphones, social media, fitness trackers, and commercial satellite imagery. Service members have inadvertently revealed the locations of secret bases through running app heat maps and posted photos that geotagged classified facilities. The digital environment has made OPSEC awareness essential for every member of the military, not just intelligence professionals.
