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. 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
