What cover sheet is attached to help protect a Secret document?
The SF 704, a red cover sheet, is attached to protect a Secret document. It shields the contents from unauthorized viewing and clearly signals the Secret classification level to anyone handling the material.
The answer
The correct cover sheet for a Secret document is the Standard Form 704 (SF 704), which is red. It is placed on the front of a classified document to block casual or unauthorized viewing and to alert everyone who handles it that the material is classified at the Secret level.
Classified cover sheets are a simple but important physical safeguard. They prevent "shoulder surfing," remind users that special handling and storage rules apply, and make the classification level instantly recognizable by color even before anyone reads the markings.
The three standard cover sheets
The U.S. government uses a color-coded set of Standard Forms, one for each of the three classification levels:
- SF 703 = Top Secret = orange. Used for the most sensitive material, whose unauthorized disclosure could cause exceptionally grave damage to national security.
- SF 704 = Secret = red. Used for material whose unauthorized disclosure could cause serious damage to national security. This is the one in the question.
- SF 705 = Confidential = blue. Used for material whose unauthorized disclosure could cause damage to national security.
A quick way to remember the order: as sensitivity rises from Confidential to Secret to Top Secret, the forms count up 705, 704, 703, and the colors run blue, red, orange.
Why the other options are wrong
- SF 703 (orange) is for Top Secret, a higher level than Secret, so it is not the right sheet for a Secret document.
- SF 705 (blue) is for Confidential, a lower level, so it under-marks a Secret document.
- A colored folder or generic label alone does not satisfy the requirement; the specific Standard Form cover sheet is what identifies the level and provides the visual barrier.
Using the wrong-level cover sheet is a marking error that can lead to mishandling, either over-restricting a document or, more dangerously, under-protecting it.
The bigger picture
Cover sheets are only one layer of classified information control. They are attached whenever a document is removed from secure storage and in use, and they are removed before the document is stored in an approved security container or before it is destroyed, since the container itself provides protection. They work alongside portion markings, banner lines, classification authority blocks, and approved storage to keep classified material safe throughout its life cycle. Knowing the color-to-level pairing (orange/red/blue for Top Secret/Secret/Confidential) is a standard part of security-awareness training.
| SF 703 | Top Secret | Orange | Exceptionally grave damage |
| SF 704 | Secret | Red | Serious damage |
| SF 705 | Confidential | Blue | Damage |
Frequently asked
What color is the SF 704 cover sheet?
The SF 704 cover sheet is red. Red is the standard color used to identify Secret-level classified documents, making the classification level recognizable at a glance before the markings are even read.
What cover sheet is used for Top Secret documents?
Top Secret documents use the SF 703 cover sheet, which is orange. Top Secret is the highest classification level, reserved for information whose unauthorized disclosure could cause exceptionally grave damage to national security.
What is the SF 705 cover sheet for?
The SF 705 cover sheet, which is blue, is used for Confidential documents. Confidential is the lowest of the three classification levels, applied to information whose disclosure could cause damage to national security.
When is a classified cover sheet removed?
A cover sheet is removed before the document is placed in an approved security container for storage or before destruction, because the container itself protects the material. It stays attached while the document is out of storage and in use.
