AIR FORCE ACADEMY, Colo. The U.S. service academies are ramping up efforts to groom a new breed of cyberspace warriors to confront increasing threats to the nation's military and civilian computer networks that control everything from electrical power grids to the banking system.
Students at the Army, Navy and Air Force academies are taking more courses and participating in elaborate cyberwarfare exercises as the military educates a generation of future commanders in the theory and practice of computer warfare.
The academies have been training cadets in cyber for more than a decade. But the effort has taken on new urgency amid warnings that hostile nations or organizations might be capable of crippling attacks on critical networks.
James Clapper, director of national intelligence, called cyberattack the top threat to national security when he presented the annual Worldwide Threat Assessment to Congress this month. "Threats are more diverse, interconnected, and viral than at any time in history," his report stated. "Destruction can be invisible, latent, and progressive."
China-based hackers have long been accused of cyber intrusions, and earlier this year the cybersecurity firm Mandiant released a report with new details. This year, The New York Times, The Wall Street Journal and The Washington Post all reported breaches in their computer systems and said they suspected Chinese hackers. China denies carrying out cyberattacks.
On Tuesday, hackers compromised Associated Press Twitter accounts and sent out a false tweet. AP quickly put out word that the report was false and that its accounts had been hacked. AP's accounts were shut down until the problem was corrected.
Once viewed as an obscure and even nerdy pursuit, cyber is now seen as one of the hottest fields in warfare "a great career field in the future," said Ryan Zacher, a junior at the Air Force Academy outside Colorado Springs, Colo., who switched from aeronautical engineering to computer science.
Last year the U.S. Naval Academy in Annapolis, Md., began requiring freshmen to take a semester on cybersecurity, and it is adding a second required cyber course for juniors next year.
The school offered a major in cyber operations for the first time this year to the freshman class, and 33 midshipmen, or about 3 percent of the freshmen, signed up for it. Another 79 are majoring in computer engineering, information technology or computer science, bringing majors with a computer emphasis to about 10 percent of the class.
"There's a great deal of interest, much more than we could possibly, initially, entertain," said the academy's superintendent, Vice Adm. Michael Miller.
Since 2004, the Air Force Academy has offered a degree in computer science-cyberwarfare initially called computer science-information assurance that requires cadets to take courses in cryptology, information warfare and network security in addition to standard computer science. The academy is retooling a freshman computing course so that more than half its content is about cyberspace, and is looking into adding another cyber course.
"All of these cadets know that they are going to be on the front lines defending the nation in cyber," said Martin Carlisle, a computer science professor at the Air Force Academy and director of the school's Center for Cyberspace Research.
About 25 Air Force cadets will graduate this year with the computer science-cyberwarfare degree, and many will go on to advanced studies and work in their service's cyber headquarters or for U.S. Cyber Command at Fort Meade, Md., the Defense Department command responsible for defensive and offensive cyberwarfare.
