OPSECâs most important characteristic is that it is a process. It is an analytical process that can be applied to any operation or activity for the purpose of denying critical information to an adversary.
OPSEC is threat driven, concerned with specific identified threat(s) against an activity where traditional security programs concentrate on a generalized threat and are not situation-specific. OPSEC is a fluid process that is controlled by the commander; it is not a lock-step program solely directed by regulations. OPSEC addresses all exploitable sources of information, not just the classified. It looks at what we have to do and how we operate.
