A security clearance is granted to an individual and generally recognizes a maximum level of clearance. Exceptions include levels above compartmentalized access or when an individual is cleared for a certain type of data. The
President of the United States will be given access to any government or military information that they request, even if they would not otherwise be able to normally obtain a security clearance were they not the President. Having obtained a certain level security clearance does not mean that one automatically has access to or is given access to information cleared for that clearance level in the absence of a demonstrated "need to know". The need-to-know determination is made by a disclosure officer, who may work in the office of origin of the information. The specified need to know must be germane to the prospective user's mission, or of necessity for the integrity of a specified security apparatus.
Controlled Unclassified Controlled Unclassified does not represent a clearance designation, but rather a clearance level at which information distribution is controlled. Controlled Unclassified designates information that may be illegal to distribute. This information is available when needed by government employees, such as United States Department of Defense (DoD) employees, but the designation signifies that the information should not be redistributed to users not designated to use it on an operational basis. For example, the organization and processes of an information-technology system may be designated Controlled Unclassified to users for whom the operational details of the system are non-critical.
Public Trust Position Despite common misconception, this designation is not a security clearance, and is not the same as the confidential designation. Certain positions which require access to sensitive information, but not information which is classified, must obtain this designation through a background check. In the US, Public Trust Positions can either be moderate-risk or high-risk. Depending on the federal agency involved, individuals found unsuitable may be able to appeal that decision.
Confidential This is hierarchically the first security clearance to get, typically requiring a few weeks to a few months of investigation. A Confidential clearance requires a NACLC investigation which dates back 7 years on the subject's record and must be renewed (with another investigation) every 15 years.
Secret A Secret clearance, also known as Collateral Secret or Ordinary Secret, requires a few months to a year to investigate, depending on the individual's background. Some instances wherein individuals would take longer than normal to be investigated are many past residences, having residences in foreign countries, having relatives outside the United States, or significant ties with non-US citizens. Unpaid bills as well as criminal charges will more than likely disqualify an applicant for approval. However, a bankruptcy will be evaluated on a case-by-case basis and is not an automatic disqualifier. Poor financial history is the number-one cause of rejection, and foreign activities and criminal record are also common causes for disqualification. A Secret clearance requires a NACLC, and a Credit investigation; it must also be re-investigated every 10 years. Investigative requirements for DoD clearances, which apply to most civilian contractor situations, are contained in the Personnel Security Program issuance known as DoD Regulation 5200.2-R, at part C3.4.2.
Top Secret Top Secret is a more stringent clearance. A Top Secret, or "TS", clearance, is often given as the result of a
Single Scope Background Investigation, or SSBI. Top Secret clearances, in general, afford one access to data that affects
national security,
counterterrorism/
counterintelligence, or other highly sensitive data. There are far fewer individuals with TS clearances than Secret clearances. A TS clearance can take as few as 3 to 6 months to obtain, but often it takes 6 to 18 months. In most instances, an individual with Top Secret clearance undergoes an SSBI Period Reinvestigation (SSBI-PR) every five years.{{cite web The US Department of Defense establishes, separately from intelligence compartments,
special access programs (SAP) when the vulnerability of specific information is considered exceptional and the normal criteria for determining eligibility for access applicable to information classified at the same level are not deemed sufficient to protect the information from unauthorized disclosure. The number of people cleared for access to such programs is typically kept low. Information about
stealth technology, for example, often requires such access. Area-specific clearances include: •
L clearance (Department of Energy) •
Q clearance (Department of Energy) •
