"The Information Security Oversight Office (ISOO), under the authority of Executive Orders 13526, 'Classified National Security Information,' and 13556, 'Controlled Unclassified Information,' oversees both the Classified National Security Information (CNSI) and Controlled Unclassified Information (CUI) programs. Enclosed is ISOO's Report for Fiscal Year (FY) 2017. It depicts the current health and status of the security classification system and the implementation of the CUI program. It provides findings and recommendations that will improve and modernize both programs. ISOO recommendations support modernizing the security classification system to transform how Government manages our classified information for the 21st century. Users of the system, both inside and outside the Government, agree that the current framework is unsustainable. Too much classification impedes the proper sharing of information necessary to respond to security threats, while too little declassification undermines the trust of the American people in their Government. Reforms will require adopting strategies that increase the precision and decrease the permissiveness of security classification decisions, improve the efficiency and effectiveness of declassification programs, and use modern technology in security classification programs across the Government."
