With advances in technology, our nation has become more reliant on cyber physical systems—systems in which computer networks control physical systems. Cyber physical systems offer greater efficiencies through reduced manpower, faster responsiveness and other capabilities. However, the systems are also more vulnerable to cyberattacks.

Cyber physical systems are commonly used in the everyday operations of utilities and they also play a role in a number of other critical infrastructures—from the traffic lights on street corners to the systems controlling machinery. Cyber physical systems also include GPS-based technologies, which have virtually replaced paper maps in recent years. It is important that these networks are protected, secure and able to run smoothly despite unwanted interference by external forces or conditions.

RSD is developing technologies to identify the extent to which GPS is used in critical infrastructure sectors and to assess the attack points that might be exploited. RSD’s GPS Vulnerability Assessment in the Critical Infrastructure project will help ensure infrastructure sectors are not disrupted by attackers that might attempt to “spoof” valid commands to control systems or otherwise interfere in their operation.
