What does "Operational Security" help to protect?

Operational Security, commonly referred to as OPSEC, is primarily focused on protecting sensitive information from adversaries. This is critical because various types of data—such as operational plans, personnel information, and other strategic details—could be exploited by adversaries if they fall into the wrong hands. Effective OPSEC involves identifying critical information, analyzing potential vulnerabilities, and implementing measures to prevent unauthorized access or disclosure.

The essence of OPSEC is to maintain the confidentiality of information that could compromise an operation or mission if it were to be intercepted or accessed by adversaries. By ensuring that sensitive information remains secure, OPSEC contributes significantly to the overall effectiveness and success of military and security operations, thus safeguarding personnel and resources from potential threats or attacks.
