security clearance levels

Security clearance levels are authorizations that grant individuals access to sensitive information based on their need and trustworthiness. They typically include levels like Confidential, Secret, and Top Secret, with each increasing in sensitivity. A higher clearance means the person has undergone thorough background checks and is trusted to handle more classified materials. Clearances are used by government agencies and some private organizations to protect national security and important data, ensuring only qualified personnel access the necessary information while maintaining security protocols.
