ATLANTA — The United States Department of Homeland Security is responding to a letter from Georgia's Secretary of State after an apparent cyber attack, trying to breach the fire wall of the department's computer system.

DHS confirmed the IP address tied to the unsuccessful cyber attack came from a US Customs and Border Protection Internet Gateway. That agency falls under DHS.
