The Pentagon has approved plans for a five-fold increase in its cyberwar fighting force. The U.S. Cyber Command would see its ranks jump from 900 to 4,900, including both uniformed and civilian personnel. Defense officials say the boost in the cybersecurity force is necessary because of the nation's growing vulnerability to cyber attacks and also the need to prepare for more offensive cyber combat operations. But there is already a shortage of cyber specialists, and the new recruitment effort would increase the competition for skilled personnel within the government and the private sector.
