What should be done if classified information is found to be improperly marked?

When classified information is found to be improperly marked, the appropriate action is to correct it immediately. This is crucial because properly marking classified information is a fundamental part of maintaining the integrity and security of sensitive data. Incorrect markings can lead to unauthorized access or mishandling of the information, which could have serious implications for national security.

By correcting the markings right away, one ensures that everyone who accesses the information understands its classification level and handles it appropriately. This proactive measure helps prevent potential security breaches and maintains compliance with established protocols regarding classified information. Keeping documents accurately marked is essential to the safe management of classified materials and upholds the responsibilities entrusted to personnel handling such information.
