I just found a defintion inside the definitions section of a DoD manual:

Sensitive Compartmented Information, ClassifiedOf course, I'm inserting these definitions in my list of acronyms and glossary.
information concerning or derived from intelligence
sources, methods, or analytical processes, that is required
to be handled within formal access control systems established
by the Director of Central Intelligence (DCI).
