What are the 4 Levels of Security Clearance?
Security clearances are categorized into four primary levels: Confidential, Secret, Top Secret, and Sensitive Compartmented Information (SCI). These levels determine the degree of access an individual has to classified information, based on the sensitivity and potential impact on national security if disclosed.
What is Security Clearance?
Security clearance is a status granted to individuals, allowing them access to classified information. It is a critical part of maintaining national security, ensuring that sensitive data is protected from unauthorized access. The clearance process involves a thorough background check, assessing factors such as loyalty, trustworthiness, and reliability.
The 4 Levels of Security Clearance
1. Confidential Clearance
