The Washington Post's Ellen Nakashima reports that the Pentagon has approved a significant increase in the size of its cyber security force, from 900 personnel to 4,900.

"The move, requested by the head of the Defense Department’s Cyber Command, is part of an effort to turn an organization that has focused largely on defensive measures into the equivalent of an Internet-era fighting force," Nakashima writes.

"As part of the expansion, officials said the Pentagon was planning three different forces under Cyber Command: 'national mission forces' to protect computer systems that support the nation’s power grid and critical infrastructure; 'combat mission forces' to plan and execute attacks on adversaries; and 'cyber protection forces' to secure the Pentagon’s computer systems," writes The New York Times' Elisabeth Bumiller.

"That is not exactly a small recruiting effort, so it will no doubt take a substantial amount of time before the new Cyber Command team is put in place," writes Geek.com's Mark Raby. "As for how the government plans to fund this colossal outreach, the Pentagon will make cutbacks in many of its other areas of operation, including those within the conventional armed forces. Cyber warfare is where the growing threat is."

"The news comes just a few days after Janet Napolitano, secretary of the Department of Homeland Security, warned that a nation-level incident of the scale of 9/11 could occur sometime soon as a result of a cyber attack," notes Threatpost's Dennis Fisher.
