14 C.F.R. Subpart C—Classification Principles and Considerations
Title 14 - Aeronautics and Space
In general, the types of NASA-generated information and material requiring protection in the interest of national security lie in the areas of applied research, technology or operations. Classifiers shall identify the level of classification of each classified portion of a document (including subject and titles), and those portions that are not classified. An interrelationship of individual items, classified or unclassified, may result in a combined item requiring a higher classification than that of any of the individual items. Compilations of unclassified information are considered unclassified unless some additional significant factor is added in the process of compilation. For example: (a) The way unclassified information is compiled may be classified; (b) The fact that the information is complete for its intended purpose may be classified; or (c) The fact the compilation represents an official evaluation may be classified. In these cases, the compilations would be classified. The degree of intended dissemination, use of the information and whether the end purpose to be served renders effective security control impractical are considerations during the classification process. These factors do not necessarily preclude classification, but must be considered in order not to impose security controls which are impractical to enforce. The effect of security protection on program progess and cost and on other functional activities of NASA should be considered. Impeditive effects and added costs inherent in a security classification must be assessed in light of the detrimental effects on the national security interests which would result from failure to classify. Restricted Data or Formerly Restricted Data is so classified when originated, as required by the Atomic Energy Act of 1954, as amended. Specific guidance for the classification of Restricted Data is provided in “Classification Guides” published by the Department of Energy.
