Know What You’re Showing
An introduction to operational security thinking
OPSEC is not a checklist or a set of tools — it is an analytical process for identifying what information you are showing, to whom, and what can be done about it. This course teaches the complete five-step process from first principles, building toward a personal OPSEC assessment you will carry into SEC-06 Applied OPSEC.
No prerequisites are required for this course. SEC-02 is a standalone introduction to OPSEC fundamentals. Upon completion, students should proceed to SEC-06 Applied OPSEC, which builds operational implementation directly on the analytical foundation developed here. Students who have also completed SEC-01 MAG Vetting will find the threat analysis material particularly reinforcing.
What You Will Build
By the end of this course you will have completed your first OPSEC cycle: a Critical Information List specific to your household or group, a threat assessment with named adversaries and capability analysis, a prioritized vulnerability list derived from the intersection of your indicators and your threats, a risk-ranked action list, and a countermeasure plan. This is the document you will carry into SEC-06.
The course takes approximately one hour to read through, but the analytical work — the drills in each lesson — will take additional time depending on how seriously you engage with them. The quality of your output is proportional to that engagement.
