A security clearance is official permission granted by a government agency, such as the Department of Defense, that allows an individual to access classified national security information up to a certain level, like 'Secret' or 'Top Secret'. This permission is only given after a rigorous background investigation confirms the individual's trustworthiness.

TECHNICAL DEFINITION
A security clearance is a formal authorization granted by a national governmental entity or defense organization, subsequent to a comprehensive background investigation, that permits an individual to access classified national security information, restricted areas, or specific programs, thereby enabling their participation in sensitive military, intelligence, or cybersecurity roles.
