What does the Security Classification Guide help determine?

The Security Classification Guide plays a critical role in determining the specific levels and categories of information that require classification. This guide outlines the criteria and standards for classifying information based on its sensitivity and the potential impact on national security. It is essential because it standardizes the classification process, ensuring that all classified information is appropriately protected based on its sensitivity level.

By establishing clear guidelines, the Security Classification Guide helps ensure that sensitive information is not mistakenly over- or under-classified, thus maintaining the integrity and security of national defense operations. It assists personnel in understanding what information should be categorized as confidential, secret, or top secret, depending on the details outlined in the guide.
