Define operation security?

Operation security, also known as OPSEC, refers to the process of identifying and protecting critical information that could be exploited by adversaries to compromise the security or success of an operation. It involves the systematic analysis of potential threats, vulnerabilities, and risks to determine the necessary measures to safeguard sensitive information. The goal of operation security is to prevent unauthorized access, disclosure, or manipulation of information that could be used to gain an advantage or compromise the mission or objectives of an organization or operation. This includes protecting information related to personnel, activities, plans, capabilities, and resources.
