The Defense Department is giving Carnegie Mellon University $35.5 million to develop tools and tactics for fighting cyberterrorism.

The center is researching ways to build AI into hardware so that components such as disk drives could take countermeasures in a hacker attack, shutting down or automatically reporting an incident to network administrators.

CMU researchers are also studying how to use signatures, fingerprints, iris patterns, face recognition technology and voice scans to confirm the identity of computer users.
