When marking sensitive compartmented information, it is important to follow the right procedures. You should refer to the appropriate guidance document, such as the Department of Defense (DoD) 5200.1-R, for details. The guidance provides instructions for both controlled and unclassified information.


Guidelines for marking sensitive compartmented information (SCI) is a process for ensuring the security and confidentiality of classified information. The classification of information based on its nature and how it is used is critical for national security purposes. Often, it involves information derived from multiple sources.


In order to mark classified information properly, the documents must be color-coded according to the compartment they belong to. For example, documents that are classified as COMINT must be marked in red. Similarly, historical documents must be classified as SCI. If the markings are unclear, it is a good idea to consult the Document Control Branch for clarification. The guidelines apply to all media, including printed materials.

When marking sensitive compartmented information, it is important to remember that there are three levels of classification. The first level is called TALENT KEYHOLE (TK) and the second level is called HUMINT (HCS). This classification is intended to provide enhanced protection for extremely fragile HUMINT.


The highest level of classification is Top Secret. This information must be handled in a secure environment. The facility must have formal control systems and must comply with guidelines. The facility itself may be an accredited area, building, or installation. Once classified, the document must be marked with an identifying combination of letters or numbers (a short title).

The United States Government has strict guidelines for marking sensitive compartmented information. It includes classified documents that are only available to certain people with a need-to-know. Such individuals must have security clearance and be approved by PerSec. Those who have access should follow guidelines that follow this classification.

Nondisclosure agreements

Nondisclosure agreements for sensitive compartmente information require that individuals who have access to sensitive information sign them. The agreements must include a provision for prepublication review to ensure that the information being disclosed is not used for a sensitive purpose. Sensitive compartmented information is classified for national security reasons and requires special handling. This information is often the result of intelligence work that involves highly sensitive sources or methods.

The DNI has created a form called NDA-4414 for this purpose. It sets forth explicit obligations for protecting the SCI, and is consistent with the existing E.O. and statutes. The provisions are designed to protect the confidentiality of confidential information, but employees must understand the penalties for noncompliance.

Nondisclosure agreements for sensitive compartmenteated information must also contain provisions that limit the disclosure of information. In addition to prepublication review, a nondisclosure agreement must also specify what material must be submitted for prepublication review. Typically, this means that the material cannot be disclosed unless the author has obtained permission from the relevant agency or the relevant federal law.

Federal government SAPs protect highly classified information with special safeguards and access restrictions. They may have more restrictive investigative requirements, require specialized nondisclosure agreements, and use special terminology and markings to indicate they are classified information. In addition, the government requires that such information be processed in a sensitive compartmented information facility.

Nondisclosure agreements for sensitive compartmente iformation are low-cost and easy to draft and protect private information. Organizations and individuals use them to protect confidential information from outside sources. Make sure that the document is as detailed as possible so that both parties know what information can and cannot be shared.

Colored border

Colored borders on sensitive compartmented information are used in several different ways. For example, a SCI document may have a bold, red border. A TOP SECRET document may have an orange border. This distinction is necessary because the contents of both kinds of documents may contain highly sensitive information.

Codes used to mark sensitive compartmented information

Sensitive Compartmented Information (SCI) is a system in which information is classified as top secret and only accessible by individuals with a ‘need to know’. This system is used for sensitive national intelligence information and is further broken down into subcompartments.

Information is classified according to its importance, and it may be marked with special markings to distinguish it from unclassified materials. These markings may include one word, an acronym or a two-word code. For example, the code for the NSA’s domestic telephone surveillance program would be “Handle through COMINT Channels Only.” The information in this program is classified as sensitive intelligence activities.

Marking sensitive compartmented information is important for national security. This classification is intended to keep information out of the wrong hands. Most SCI documents will have a color-coded cover sheet, with red indicating COMINT, black for SCI, and orange for Non-SCI classified documents. These documents must be protected by strict and formal control systems.

When a company has sensitive compartmented information, the employees in that organization are required to have a security clearance. These employees may include military personnel, diplomats, contractors, or other people with high levels of security clearance. They are required to undergo a polygraph test and a Single Scope Background Investigation before they can access this type of information.

The classification system for classified information is quite complex. The United States Department of Defense, Department of Energy, and the intelligence community have created a number of compartmented control systems. However, the classification system creates unnecessary costs. This is why the Director of National Intelligence has sought to create a more transparent marking system.

Unlike other forms of classified information, sensitive compartmented information is separated from the unclassified world by physical barriers. This system is designed to ensure that only authorized personnel have access to this type of information. For example, STELLARWIND, developed by the US Department of Defense, is a system to store classified documents on a network using AES encryption. Another similar system is STLW, which uses symmetric key encryption. These systems operate at trusted military sites.
