SCI is one of eight categories of information that require classified protection as outlined in Executive Order 13526.

• A. True
• B. False
• C. It Is a Subset of Top Secret
• D. It Is Not Defined by EO 13526

Answer: (A)

Executive Order 13526 identifies eight categories of information that require classification protection, and Sensitive Compartmented Information fits within that protective framework. SCI stands for highly sensitive intelligence information that, while still classified, is protected not only by the overall Top Secret level but also by separate compartments to safeguard sources and methods. This compartmentalized handling is part of how the order structures information protection, so the assertion that SCI is among the categories requiring classification is accurate in this context.

Note: SCI is more about the special handling and access controls than just being a subset of Top Secret, and EO 13526 defines the broader system that includes SCI within its protective scheme.
