What is SCI in the context of information security?

• A. A subset of Top Secret information restricted by compartmentalization.
• B. A category of information that does not require clearance.
• C. A form of information storage.
• D. A security policy for admin staff.

Answer: (A)

Sensitive Compartmented Information designates highly sensitive material that is Top Secret but protected by additional, separately controlled compartments. Access is limited to individuals who have a Top Secret clearance and have been specifically granted access to the SCI compartments they need for their work, based on a need-to-know. Handling and storage occur in specialized facilities, often called SCIFs, with strict procedures, ongoing need-to-know reviews, and enhanced monitoring. This is not simply a category that doesn’t require clearance, nor a storage form or a security policy.
