What is the current Executive Order governing security classifications?

The current Executive Order governing security classifications is E.O. 13526. This order, signed by President Obama in 2009, establishes a comprehensive framework for the classification, safeguarding, and declassification of national security information. It outlines the criteria for what constitutes classified information and specifies the responsible agencies involved in the classification process. E.O. 13526 emphasizes the importance of protecting sensitive information while also promoting transparency and accountability in government.

In contrast, E.O. 10290 is an earlier executive order from 1951 that has been superseded and is no longer relevant for current classification policies. E.O. 12345, issued in 1981, also does not reflect the current classification guidelines and has been replaced by later orders. E.O. 14030 is focused on ensuring safe and secure technology use in federal agencies but does not pertain to the classification of security information. Hence, E.O. 13526 remains the authoritative source for security classification today.
