Which level of classification is the highest?

The highest level of classification is Top Secret. This classification is applied to information that, if disclosed without proper authorization, could cause exceptionally grave damage to national security. The standards for what qualifies as Top Secret are stringent, reflecting the critical nature of the information involved.

In contrast, Confidential and Secret are lower classification levels. Confidential information can cause damage to national security, while Secret information can cause serious damage. Unclassified information does not require protection because its disclosure does not pose a risk to national security.

Understanding the hierarchy of classification levels is crucial for protecting sensitive information appropriately and ensuring that individuals handle classified data in accordance with the law and established protocols.
