What must be done to classified information when it is no longer needed?

When classified information is no longer needed, it is essential to ensure that it is properly disposed of to prevent unauthorized access or disclosure. Proper disposal methods, such as shredding physical documents or securely wiping electronic storage devices, are necessary to eliminate the risk of sensitive information falling into the wrong hands. This practice reflects the responsibility of individuals handling classified information to maintain national security and protect against potential threats.

Storing classified information indefinitely, disclosing it to the public, or keeping it for personal use do not align with established protocols for managing classified materials. Such actions could lead to significant security breaches and undermine the integrity of classified information systems. Hence, the correct approach is to ensure that classified information is disposed of in a secure and appropriate manner when it is no longer required.
