what coversheet is attached to help protect a secret document

To help protect a secret document, a cover sheet is attached to it. The cover sheet identifies the document type and department it belongs to, and it is required with classified documents. The specific cover sheet used depends on the level of classification of the document. For example, the SF-703 Top Secret Cover Sheet is used for top secret documents, the SF-704 Secret Cover Sheet is used for secret documents, and the SF-705 Confidential Cover Sheet is used for confidential documents. The SF-704 Secret Cover Sheet is a page that is meant to cover the title page of a file and serves as a shield to protect Secret classified information from inadvertent disclosure and to alert observers that the document contains classified information.
