Rep. Davis Explains Feds' Security Grade

Rep. Tom Davis, R-Va., who oversees the issuance of agencies' security grades, wrote yesterday in The Hill newspaper's Congress Blog why the government's overall security grade increased from a D plus to a C minus. The reason: More agencies like the Department of Homeland Security know what electronic equipment they have, which goes a long way in knowing what you have to protect. Still, Davis says the Defense Department's grade of F "should worry us all."

He doesn't elaborate.
