information and materials tend to consist of broad and general categories, making it potentially difficult for researchers to know whether their activities are in or out of bounds.

These considerations suggest two general principles and a number of specific recommendations:

  • Principle 1: Construct “high fences” around narrow areas—that is, maintain stringent security around sharply defined and narrowly circumscribed areas, but reduce or eliminate controls over less sensitive material.

    • Regularly review and update the lists maintained by federal agencies of information and technologies subject to controls with the goal of restricting their focus and removing controls on readily available technologies.
