223.4—Policy.
It is DoD policy:
(a)
To prohibit the unauthorized dissemination of unclassified information on security measures, including security plans, procedures, and equipment for the physical protection of DoD SNM, equipment, or facilities.
(b)
That the decision to protect unclassified information as DoD UCNI shall be based on a determination that the unauthorized dissemination of such information could reasonably be expected to have a significant adverse effect on the health and safety of the public or the common defense and security by increasing significantly the likelihood of the illegal production of nuclear weapons or the theft, diversion, or sabotage of DoD SNM, equipment, or facilities.
(c)
That government information shall be made publicly available to the fullest extent possible by applying the minimum restrictions consistent with the requirements of 10 U.S.C. 128 necessary to protect the health and safety of the public or the common defense and security.
(d)
That nothing in this part prevents a determination that information previously determined to be DoD UCNI is classified information under applicable standards of classification.
