The U.S. military has an unusual request for American cyber warriors: hack its computers and steal its data.

A new program called Hack the Pentagon aims to improve the military’s cybersecurity by testing its defenses. Rather than waiting around for an ISIS hacker to hack into the Pentagon’s mainframe and whisper “We’re in,” the military wants volunteers to do it instead. But only under specific conditions.

To embark on a “tour of duty” through Hack the Pentagon, a hacker hopeful must 1) officially register their intent with the military and 2) submit to a background check.

And before you start worrying about a global thermonuclear fiasco like the one depicted in ‘WarGames,’ the military’s most sensitive data and dangerous weapons will not be included in the tests. All hackers will be working with the same predetermined security system, keeping actual military secrets safe and sound.

“I am confident that this innovative initiative will strengthen our digital defenses and ultimately enhance our national security,” Defense Secretary Ash Carter said.

This sort of program is actually commonplace among large companies with complex cyber security systems. To get started, the military has already recruited coders from Google and Shopify.
