What is meant by 'banner markings' in classified communications?

'Banner markings' refer to classification markings that accompany the main content of a classified communication. These markings are typically found at the top and bottom of documents and provide essential information about the classification level of the material, such as whether it is Confidential, Secret, or Top Secret. The purpose of banner markings is to ensure that anyone handling the document is immediately aware of its classification level, which plays a critical role in the protection and handling of sensitive information.

Ultimately, these markings serve to promote awareness and compliance with handling procedures for classified information, ensuring individuals understand the potential risks associated with unauthorized disclosure. By clearly indicating the classification status, banner markings help to maintain the security and integrity of classified materials throughout their lifecycle.
