CHAPTER 8: Classified Correspondence


8.1 Ssfeguards and Controls and Equipment and Supplies

8.1.1. Markings. The drafting of classified correspondence is governed by NPD 1600.2A, NASA Security Policy. This is the primary reference for preparing, marking, and handling classified correspondence. Personnel with or without a security clearance should review NPD 1600.2A. All material requiring protection in the interest of national security must be marked appropriately to alert people of the classification level so that the material may be safeguarded.

8.1.2. Equipment and Supplies. To draft or reproduce classified correspondence, use only typewriters, computers, and copiers that have been specifically designated for that purpose. NASA Center Security Offices are the only organizations authorized to confirm and approve certification of equipment for these purposes.

8.1.3. Safeguards. When classified material is not under the direct control and supervision of an authorized person, it must be stored appropriately. Only Center-designated Security Offices are authorized to approve and designate storage containers.

8.1.3.1. Appropriate storage includes the use of safes, vaults, or alarmed rooms. Only GSA-approved safes may be used to store classified materials.

8.1.3.2. Ensure that all classified material is properly secured in an approved container prior to leaving your work area.

8.1.3.3. Not only must the document be stored in the safe, but so must related classified notes, drafts, and any typewriter ribbons and/or disks used in drafting the document.

8.1.3.4. There are special stickers to place on computer disks that contain classified materials. These stickers are available at your Center's Security Office.

8.2 Format and Marking

8.2.1. Except for marking requirements, prepare classified correspondence in the same format as unclassified correspondence. Executive Order 12958, Classified National Security Information, requires four specific markings that are required on classified documents. Refer to Figure 8-1.

Portion Marking

Overall Classification

A "Classification by" line

A "Declassify on" line

8.2.1.1. Portion Marking. The first step in preparing a classified document is for the writer to identify the classification, or lack thereof, of each component (subject, title, and paragraph) of the document. This ensures that the reader understands the classification of specific information. At the beginning of each paragraph, the writer annotates the classification as listed below and shown in Figure 8-3. Titles and subject lines are marked at the end of the sentence in a similar fashion.

(S) SECRET paragraph or portion

(C) CONFIDENTIAL paragraph or portion

(U) UNCLASSIFIED Portion

8.2.1.2. Overall Classification. The second step is to determine the overall classification of the document. The overall classification of a document is determined by the highest classification of any paragraph in the document. For example, in a five-paragraph document, if one paragraph is classified as SECRET, another as CONFIDENTIAL, and the remainder as UNCLASSIFIED, the overall classification of the document is SECRET. Mark the overall classification clearly at at both the top and bottom on each page of the document.

8.2.1.3. Format and Location. This overall classification must be stamped in capital letters, plainly, and conspicuously about 1/4 inch from the top and bottom of each page of the document. These overall classifications, CONFIDENTIAL, SECRET, and TOP SECRET, may be accompanied by additional information, known as caveats. Caveats are always placed below the overall classification on the top of the page and above the overall classification at the bottom of the page.

Example:

Top of the page

SECRET
NOFORN

Bottom of the page

NOFORN
SECRET

8.2.1.4. The most common caveats used in drafting classified correspondence include the following. Refer to NPR 1620.1A, Security Procedures and Guidelines, and NPD 1600.2A, NASA Security Policy, for further information.

CNWDI - Critical Nuclear Weapons Design Information
FGI - Foreign Government Information
FRD - Foreign Restricted Data
LIMDIS - Limited Dissemination
NATO - North Atlantic Treaty Organization; Releasable to the representatives of the member nations
NOCONTRACT - Restricts access from Contractor personnel
NOFORN - Restricts access from Foreign Nationals
RD - Restricted Data
SAP - Special Access Program
WNINTEL - Warning Intelligence Sources or Methods Involved

8.2.1.5. A "Classified by" Line. The "Classified by" marking identifies the original classification authority, which is the originating agency or office. This line is specifically used when the originator's name does not appear in the document, either in a "FROM" line or as the signatory of the cover letter. Place the "Classified by" marking on the bottom lower right of the front or title page. Refer to NPD 1600.2A for information on officials authorized to make classification, declassification, and downgrading decisions; procedures for declassification; and derivative classification determinations required when classified information is extracted from source documents and restated in other documents.

Example:

Classified by: Office of Space Flight

8.2.1.6. A "Declassify on" Line. This marking indicates the date the document will become declassified. Whenever possible, cite a specific date or event. If this is not possible, state "Originating Agency's Determination Required," which means that the information must be reviewed by the originator before any declassification action can be taken. Place this marking on the lower right of the cover page or first page of the document, below the "Classified by" marking.

Example:

Declassify on: January 1, 2010

8.2.1.7. Occasionally, the original classifier of a document can predetermine a date or event upon which it will be possible to downgrade the classification level rather than fully declassifying it. In those cases, instead of "Declassify on," mark as follows:

Example:

DOWNGRADE TO: SECRET
ON: July 1, 2010

or:

DOWNGRADE TO: CONFIDENTIAL
ON: Completion of the 1998 Trade Commission

8.2.1.8. Page, Copy, and Series Numbering. These marks are used to assist in page counting of SECRET and TOP SECRET documents and to ensure the ability to account for each copy of the document. These marks are applied to the upper right corner of all SECRET and TOP SECRET documents. This marking is not required for CONFIDENTIAL documents.

Example:

This Document consists
of ____ Pages.
Copy No. ____ of _____ copies
Series _________.

8.3 Transmission of Classified Correspondence

8.3.1. Transmission of Classified Correspondence (see Figure 8-2). Classified material may be transmitted and disseminated only by approved methods. Each classification level has its own specific, approved methods. Refer to NPD 1600.2A for detailed instructions. The following are the most common transmission guidelines.

8.3.1.1. Mailing Classified Material. The USPS may be used to transfer Confidential and Secret material within the United States as discussed below. However, ALL classified material to be transferred outside of the United States or its territories must be approved by the cognizant Center's Security Office.

8.3.1.2. Confidential. Send by registered or certified mail within the United States or its territories via the USPS.

8.3.1.3. Secret. Send by registered mail via the USPS.

8.3.1.4. Top Secret. NEVER send Top Secret material through any mail system. Top Secret material may only be transferred by authorized and approved electronic means or carried by cleared couriers. All Top Secret material should be logged in and out by the Top Secret Control Officer of your Center's Security Office.

8.4 Addressing Classified Correspondence

8.4.1. Always address classified material to an activity, not to an individual.

8.4.2. The outer envelope must include the complete destination address and your activity's complete return address.

8.4.3. Double-wrap classified material and correspondence; use two envelopes. The outside envelope must conform to the instructions detailed within this NPR. The inner envelope must have both addresses as shown on the outer envelope, plus the overall classification of the document being transferred. Mark the classification level on the front and back top, and bottom of the envelope.

8.4.4. The inner envelope must have both addresses as shown on the outer envelope, plus the overall classification of the document being transferred.

8.4.5. This classification mark will be placed on the front and back of the envelope and the top and bottom.

8.4.6. Attach a classified material receipt (NASA Form 387) to the inner envelope for the addressee to sign and return to your activity. This confirms that the addressee received the document. For specific instructions on sending Top Secret material, refer to NPD 1620.2A or contact the Center's Security Office. If receipt is not confirmed within 20 days, initiate tracer action. If this action does not confirm receipt, contact the Center's Security Office.

8.4.7. Internal to NASA Centers. When you take classified documents outside the work area, you must carry them in a sealed, opaque envelope to prevent advertising that you are carrying classified material. When you are using classified material within the work space, it should have a classified cover sheet on the document if it is outside of the container, e.g., on your desk.

8.4.8. External to NASA Centers. If you are required to hand-carry classified documents outside of a NASA Center, you must receive a briefing and a courier card from your Center's Security Office before you are approved to take classified documents offsite.
