However, in a November 30, 2007, report to Congress entitled "Transportation Security Administration's Processes for Designating and Releasing Sensitive Security Information", GAO said: "DHS, primarily through TSA's SSI Office, has addressed all of the legislative mandates from the DHS Appropriations Act, 2007, and taken actions to satisfy all of the recommendations from our June 2005 report. DHS revised its MD (i.e., Management Directive) to address the need for updating SSI guidance, and TSA has established more extensive SSI criteria and examples that respond to requirements in the DHS Appropriations Act, 2007, and our 2005 recommendation that TSA establish guidance and procedures for using TSA regulations to determine what constitutes SSI. Further, TSA has documented the criteria and examples in various publications to serve as guidance for identifying and designating SSI. TSA has also shared its documentation of the criteria and examples with other DHS agencies."
