OPSEC, short for Operational Security, is a process used to identify, control, and protect sensitive information that could be exploited by adversaries. It involves analyzing operations and activities to determine what information could be valuable to attackers and implementing measures to prevent unintended disclosure. OPSEC is widely used in both military and civilian contexts to safeguard critical data, prevent leaks, and reduce the risk of cyberattacks. The process typically includes identifying critical information, analyzing threats and vulnerabilities, assessing risks, and applying appropriate countermeasures. Effective OPSEC helps organizations maintain the confidentiality and integrity of their operations.
