Which practice is required for meetings involving SCI materials?

• A. Meetings may be held in any conference room.
• B. Vendors may attend meetings even if they don't have need-to-know.
• C. Display all documents on a public screen.
• D. Conduct discussions in a SCIF or approved secure space; ensure only those with need-to-know are present; avoid displaying sensitive materials.

Answer: (C)

Meetings involving SCI materials must occur in a tightly controlled environment with restricted access and controlled viewing. The proper practice is to hold discussions in a SCIF or other approved secure space, ensure only individuals with a need-to-know are present, and avoid displaying sensitive materials in any way that could be seen by unauthorized personnel. This setup minimizes the risk of inadvertent disclosure and protects the information from exposure. Holding meetings in a non-secure conference room, letting vendors attend without need-to-know, or putting documents on a public screen would all create opportunities for disclosure and are not appropriate.
