Security clearance is a determination by the U.S. government that an individual is eligible for access to classified information. The process of applying for a security clearance can be complex and time-consuming, but it is essential for individuals who wish to work in certain government positions or with certain government contractors.
There are three main types of security clearances: confidential, secret, and top secret. The type of clearance required for a particular position will depend on the sensitivity of the information that the individual will be accessing.
