Which SCI control system is designed to protect imagery intelligence?

• A. Talent Keyhole (TK)
• B. High Control System (HCS)
• C. Signals Intelligence (SI)
• D. Open Source Intelligence (OSINT)

Answer: (A)

Talent Keyhole is the SCI control system designed to protect imagery intelligence. Imagery intelligence comes from reconnaissance satellites and historical programs labeled Keyhole, so a dedicated compartment was created to tightly control who can access that data. The Talent Keyhole system ensures access is limited to individuals with the proper clearance and need-to-know, keeping sensitive imagery separate from other types of intelligence.

The other options don’t fit because they refer to different intelligence domains or aren’t SCI control systems for imagery: a term like High Control System isn’t a recognized SCI compartment for imagery; Signals Intelligence covers different data and has its own protection scheme; Open Source Intelligence is not an SCI-controlled category.
