What is the process of downgrading classified information to an unclassified level called?

The process of downgrading classified information to an unclassified level is known as declassification. This process involves formally determining that information no longer qualifies for protection under classification guidelines due to the passage of time, changes in policy, or new evidence that changes its sensitivity or importance. Declassification is essential in promoting transparency and ensuring that information can be accessed by the public or authorized individuals once it is deemed no longer sensitive.

Declassification adheres to specific protocols and is often part of overall information security and information lifecycle management policies. It is important for maintaining the balance between national security and the public’s right to know.
