What procedural steps must be followed when marking classified information?

The correct response outlines a systematic approach to marking classified information, which is essential to protect sensitive data effectively. The process involves three critical steps: first, identifying the information that needs protection; second, classifying that information based on the potential damage its unauthorized disclosure could cause; and finally, applying the appropriate markings to clearly designate the information's classification level.

By identifying the information, individuals ensure that they are only marking what is necessary, targeting data that warrants protection. Classifying the information according to potential damage helps to apply the proper degree of safeguarding—understanding whether the exposure could cause serious, moderate, or minimal harm is crucial for determining the correct classification level. Lastly, applying the appropriate markings not only communicates the classification status but also informs individuals handling the information about the required safeguarding protocols.

This method is critical for maintaining information security and adhering to governmental standards concerning classified data. Other options lack this structured approach, leading to potential security risks or non-compliance.
