Which level of classification is given to the most sensitive information?

The level of classification given to the most sensitive information is Top Secret. This designation indicates that unauthorized disclosure of the information could cause exceptionally grave damage to national security. The Top Secret classification is used for information that requires the highest level of protection and handling to ensure that it is safeguarded against unauthorized access.

It is important to recognize that other classifications, such as Secret and Confidential, denote varying levels of sensitivity, with Secret being used for information that could cause serious damage, and Confidential for information that might cause damage to national security if disclosed. Restricted is not a standard classification within the structure used for national security information and often pertains to administrative controls rather than the specific handling of classified data. The differentiation among these levels is crucial for determining the extent of safeguarding required and the impact of unauthorized disclosure.
