Fisher’s trying to stop those kinds of attacks. Traditional security methods, like anti-virus scanning, can’t solve the problem, because they focus on known families of vulnerabilities. Brand new angles of attack render those defenses useless. So do clueless users, who gets themselves pwned while trying to play Mafia Wars or open up that email promising male enhancement. And the problem gets harder when considering the vulnerabilities in hardware, like the drones themselves. (Counterfeit microchips, anyone?) “You probably can’t just reboot your car as you’re speeding down the highway,” Fisher told the colloquium.
Her answer is mostly a non-answer, like many on display at the colloquium. As one of Darpa’s program managers, she has an effort devoted to creating “high-assurance” systems — effectively, to stop the drones or their software from getting infected. How she’ll do it is unclear: she invited the nearly 700 people in the Renaissance Arlington Capitol View hotel to tell her how.
