Which of the following is NOT a way to promote the sharing of information?

The option that indicates a method not conducive to promoting the sharing of information is the one that involves restricting access based on clearance level. While security protocols that assign access by clearance level are essential for protecting sensitive information, they inherently limit how much information is shared and with whom. Clearance levels create barriers, preventing individuals without proper authorization from accessing potentially useful information, thereby reducing collaboration and information exchange among relevant parties.

On the other hand, careful use of dissemination control markings, avoiding unnecessary classification, and providing open access to all internal documents facilitate information sharing. Proper dissemination controls ensure that information is shared appropriately while still managing risk, avoiding unnecessary classification helps to keep information accessible when it doesn't need to be restricted, and providing open access maximizes the flow of information, thereby encouraging collaboration and transparency in communication.
