What Does Sensitive Compartmented Information (SCI) Mean?
Sensitive compartmented information (SCI) is information that needs extra protection above a top-secret security clearance level. SCI can come from various sources and has to have special handling, which involves controls to access. These controls are put in place by the head of the CIA, known as the director of central intelligence (DCI).
Only those with a special designation - obtained via a single scope background investigation (SSBI) - will be able to view SCI.
Sensitive compartmented information is often called codeword information.
