The Pentagon's Cyber Command will create 40 offensive cybersecurity teams by the fall of 2015 to help defend the nation against major computer attacks and assist combat commands as they plan offensive capabilities, Gen. Keith Alexander said Tuesday.
The new teams are part of a broader government effort to shield the nation from destructive attacks over the Internet that could harm Wall Street or knock out electric power, for instance.
Some teams are already in place, he said, to focus on "the most serious threats," which he did not identify.
