Technological and operational information and material, and in some exceptional cases scientific information falling within any one or more of the following categories, must be classified if its unauthorized disclosure could reasonably be expected to cause some degree of damage to the national security. In cases where it is believed that a contrary course of action would better serve the national interests, the matter should be referred to the Chairperson, NISPC, for a determination. It is not intended that this list be exclusive; original classifiers are responsible for initially classifying any other type of information which, in their judgment, requires protection under § 1.4 of "the Order."
