In military and government organizations, and some private organizations, a system of compartmenting information exists to prevent the uncontrolled dissemination of information considered to be sensitive or confidential. Persons with a legitimate need to have access to such information are issued security clearances, which can be tracked and verified to ensure that no unauthorized persons gain access to protected information.
Security clearances are among the most carefully guarded credentials. Often they are granted to individuals only after a lengthy investigation and only after their need to have access to protected information has been adequately justified to the issuing authority. The most elaborate security-clearance systems are found in the world's military organizations. Some credentials of this type are considered so sensitive that their holders are not even permitted to acknowledge that they have them (except to authorized parties).
Breaches of security involving security clearances are often punished by specific statutory law, particularly if they occur in the context of deliberate espionage, whereas most other counterfeiting and misuse of credentials is punished by law only when used with deliberate intent to defraud in specific contexts.
Documentation of security clearances usually consists of records keep at a secure facility and verifiable on demand from authorized parties.
Security clearances are regularly withdrawn when they are no longer justified, or when the person holding them is determined to be too great a security risk.

Famous quotes containing the word security:
“If we could have any security against moods! If the profoundest prophet could be holden to his words, and the hearer who is ready to sell all and join the crusade, could have any certificate that to-morrow his prophet shall not unsay his testimony!”
—Ralph Waldo Emerson (18031882)
