What is classified information concerning intelligence sources known as?

Classified information concerning intelligence sources is specifically referred to as Sensitive Compartmented Information (SCI). SCI is a classification that protects information collected through specific intelligence methods or sources, ensuring that the details regarding these methods and the information they yield are safeguarded from unauthorized disclosure.

Understanding SCI is vital for maintaining the integrity and security of intelligence operations. It helps ensure that only individuals with the appropriate clearance and a need-to-know are granted access to this sensitive information, thereby minimizing the risk of compromising intelligence sources and methods.

The other terms listed do not pertain specifically to classified intelligence sources. SCIF (Sensitive Compartmented Information Facility) refers to a secure area where SCI can be accessed and discussed, but it does not define the information itself. STA (Special Trust Authority) and SID (Strategic Intelligence Directive) are not terms used to classify information concerning intelligence sources. By recognizing these distinctions, it becomes clear why Sensitive Compartmented Information is the appropriate classification in this context.
