Operations security

Operations security (OPSEC) is a process of identifying critical information and subsequently analyzing friendly actions attendant to military operations and other activities to:


 * a. identify those actions that can be observed by adversary intelligence systems;
 * b. determine indicators that hostile intelligence systems might obtain that could be interpreted or pieced together to derive critical information in time to be useful to adversaries; and
 * c. select and execute measures that eliminate or reduce to an acceptable level the vulnerabilities of friendly actions to adversary exploitation.
