You don’t have an OPSEC problem. You have six of them, and most are sitting in your driveway, your trash can, and your phone.
Social media posts. The neighbor who means well. Photos with GPS data baked in. Mail nobody shreds. Location tracking you never turned off. Passwords sitting next to the laptop.
None of these feel like a threat on their own. That’s exactly the problem. An adversary doesn’t need one big mistake. They need a handful of small, ordinary ones that combine into a pattern.
Online self-study courses:
SEC-02: Know What You’re Showing teaches you the five-step process to find that pattern before someone else does.
SEC-06: Applied OPSEC takes it further, a full digital and physical signature audit and a written countermeasure plan built on your own household’s real exposure.
