Cyberattacks on government up 680 percent

Cyberattacks on the federal government soared 680 percent in five years, an official from the Government Accountability Office (GAO) testified.

Gregory Wilshusen, director of information issues for the GAO, said federal agencies reported 42,887 cybersecurity "incidents" in 2011, compared with just 5,503 in 2006. The incidents included malicious code, denial of service attacks and unauthorized access to systems. He said foreign nations, terrorists, criminal groups and political activists were behind many of the attacks. "These agencies and organizations have experienced a wide range of incidents involving data loss or theft, computer intrusions and privacy breaches, underscoring the need for improved security practices computer intrusions, and privacy breaches," Wilshusen testified at a hearing of the House Homeland Security Committee's subcommittee on Oversight, Investigations and Management. He said securing critical infrastructure systems, such as electrical grids or chemical plants, should be a "national priority."
