词条 | Sensitive Compartmented Information |
释义 |
SCI is not a classification. SCI clearance has sometimes been called "above Top Secret,"[3] but information at any classification level may exist within an SCI control system. When "decompartmentalized" this information is treated the same as collateral information at the same classification level. AccessEligibility for access to SCI is determined by a Single Scope Background Investigation (SSBI) or periodic reinvestigation.[4] Because the same investigation is used to grant Top Secret security clearances, the two are often written together as TS/SCI. Eligibility alone does not confer access to any specific SCI material; it is simply a qualification. One must receive explicit permission to access an SCI control system or compartment. This process may include a polygraph or other approved investigative or adjudicative action.[5] Once it is determined a person should have access to an SCI compartment, they sign a nondisclosure agreement, are "read in" or indoctrinated, and the fact of this access is recorded in a local access register or in a computer database. Upon termination from a particular compartment, the employee again signs the nondisclosure agreement. Control systemsSCI is divided into control systems, which are further subdivided into compartments and sub-compartments. These systems and compartments are usually identified by a classified codeword. Several such codewords have been declassified. The following SCI control systems, with their abbreviations and compartments, are known:
SI has several compartments, of which the following are known or declassified:
Several now-retired codewords protected SI compartments based on their sensitivity, generally referred to as Top Secret Codeword (TSC) and Secret Codeword (SC).[10] These codewords were:
These three codewords, the usage of which was terminated in 1999,[12] were attached directly to the classification without reference to COMINT or SI, e.g. Top Secret UMBRA.
MarkingsSCI control system markings are placed immediately after the classification level markings in a banner line or portion marking.[23] Sometimes, especially on older documents, they are stamped. The following banner line and portion marking describe a top secret document containing information from the notional SI-GAMMA 1234 subcompartment, the notional SI-MANSION compartment, and the notional TALENT KEYHOLE-LANTERN compartment: Older documents were marked with HANDLE VIA xxxx CONTROL CHANNELS (or "HVxCC"), HANDLE VIA xxxx CHANNELS ONLY (or "HVxCO"), or HANDLE VIA xxxx CHANNELS JOINTLY (or "HVxCJ"), but this requirement was rescinded in 2006.[24] For example, COMINT documents were marked as HANDLE VIA COMINT CHANNELS ONLY. This marking led to the use of the caveat CCO (COMINT Channels Only) in portion markings,[25] but CCO is also obsolete.[26] Notes1. ^ICD 1, p. 22 2. ^DCID 3/29 3. ^Robert S.
