What does "access control" refer to regarding classified information?

Access control in the context of classified information refers to the regulations and procedures that are established to restrict who can view or use classified data. This system is essential because it helps protect sensitive information from unauthorized individuals, thereby maintaining national security and safeguarding private and proprietary data. By implementing stringent protocols, organizations can ensure that only those individuals who have the proper clearance and a legitimate need to know are granted access to classified materials. Effective access control measures include various strategies such as background checks, security clearances, and role-based access permissions, all designed to minimize the risk of unauthorized disclosure.
