  7. Derivative Classification. Incorporating, paraphrasing, restating, or generating in

    Duplication or reproduction of classified information is not derivative
    classification. E.O. 13526 § 6.1(o).
  8. Levels of Classification. E.O. 13526 § 1.2.
    1. Top Secret. Information, the unauthorized disclosure of which
      reasonably could be expected to cause exceptionally grave damage to
      the national security that the OCA is able to identify or describe.
    2. Secret. Information, the unauthorized disclosure of which reasonably
      could be expected to cause serious damage to the national security that
      the OCA is able to identify or describe.
    3. Confidential. Information, the unauthorized disclosure of which
      reasonably could be expected to cause damage to the national security
      that the OCA is able to identify or describe.
  9. Compartmented Information. Information within a formal system which strictly
    controls the dissemination, handling and storage of a specific class of classified
    information. Another name for compartmented information is “codeword
    information.” See Code 17 Handbook, Chapter 2. There are two categories of
    compartmented information:

    1. Special Access Program (SAP). A program established safeguarding and
      access requirements that exceed those normally required for information
      at the same classification level. A person must obtain authorized access
      to SAP information by completing personnel security requirements
      unique to the SAP and signing a SAP nondisclosure agreement.
      Furthermore, the person may not disclose SAP information to anyone
      without verifying that the other person has access to the SAP and a
      verified need-to-know the information.
    2. Sensitive Compartmented Information (SCI). Classified information
      concerning or derived from intelligence sources, methods, or analytical
      processes that is required to be handled exclusively within formal access
      control systems established by the Director of Central Intelligence.
    3. “Need to Know.” A determination made by an authorized holder of classified
      information that a prospective recipient requires access to specific classified
      information in order to perform or assist in a lawful and authorized governmental
      function. E.O. 13526, § 6.1(dd). In order to gain access to classified
      information, a person must satisfy two requirements: (1) The appropriate
      authority must deem the person suitable for receiving classified materials; and (2)
      the person must have a “need-to-know” the classified material. See Schmidt v.
      Boone, 59 M.J. 841, 852 (A.F. Ct. Crim. App. 2004), rev’d on other grounds sub
      nom., United States v. Schmidt, 60 M.J. 1 (2004).
