The S4x13 agenda is dominated by strong offensive security presentations with a sprinkling of defense. So we are pleased to add one last defensive security session to the agenda from Dr. Jonathan Butts and Stephen Dunlap of the Air Force Institute of Technology.This presentation introduces a novel approach of using CPU execution data to characterize the nominal operations of a PLC. The technique provides the ability to remotely fingerprint a device and measure characteristics that fluctuate if a change to the firmware or program file occurs. The session will demonstrate how the method can be applied to detect modifications to PLC program files, firmware and communication, as well as search devices for known malware.
