"Federal agencies increasingly use recently developed Internet technologies that allow individuals or groups to create, organize, comment on, and share online content. The use of these social media services- including popular Web sites like Facebook, Twitter, and YouTube- has been endorsed by President Obama and provides opportunities for agencies to more readily share information with and solicit feedback from the public. However, these services may also pose risks to the adequate protection of both personal and government information. GAO was asked to (1) describe how federal agencies are currently using commercially provided social media services and (2) determine the extent to which agencies have developed and implemented policies and procedures for managing and protecting information associated with this use. To do this, GAO examined the headquarters-level Facebook pages, Twitter accounts, and YouTube channels of 24 major federal agencies; reviewed pertinent policies, procedures, and guidance; and interviewed officials involved in agency use of social media.
