When including a classified photograph of a new weapons system on a webpage, which markings apply?

When a classified photograph of a new weapons system is included on a webpage, it is crucial to apply both banner markings and portion markings to ensure proper handling and safeguarding of the information. Banner markings provide a clear indication of the overall classification level of the document, while portion markings are used to identify the classification level of specific sections or elements within that document. This dual approach is necessary for effective communication of the classification status, ensuring that all personnel interacting with the content understand its sensitivity and the requisite precautions required to handle it appropriately.

Using banner markings signals to users the classification level—such as Confidential, Secret, or Top Secret—and helps prevent unauthorized access or disclosure. Portion markings further enhance this by indicating if only part of the content is classified, allowing for more flexible sharing and discussion of non-sensitive information while still protecting sensitive elements. Thus, employing both markings fulfills regulatory requirements and promotes a culture of security awareness.
