Which category is included in SCI?

• A. Intelligence activities, sources or methods, or cryptology
• B. Physical security measures only
• C. Public information
• D. Non-sensitive personal data

Answer: (A)

Sci categorizes highly sensitive information by what it concerns, and one specific category covers intelligence activities, sources or methods, or cryptology. This reflects the kinds of material that require SCI protection: details about how intelligence is collected, who or what provides that information, and the cryptologic techniques used to protect or extract intelligence. That’s why this category is the correct choice.

Physical security measures are essential safeguards for protecting SCI, but they describe how the information is protected rather than what the information is about, so they aren’t a category of SCI content. Public information and non-sensitive personal data are not restricted and do not fall under SCI categories.
