Operations Security (OPSEC) is the process by which we protect critical information whether it is classified or unclassified that can be used against us. It focuses on preventing our adversaries' access to information and actions that may compromise an operation. OPSEC challenges us to look at ourselves through the eyes of an adversary and deny the adversary the ability to act.
