Abstract :
The growing connectivity of cyber-physical systems (CPSes) has led to an increased concern over the ability of cyber-attacks to inflict physical damage. Current cyber-security measures focus on preventing attacks from penetrating control supervisory networks. These reactive techniques, however, are often plagued with vulnerabilities and zero-day exploits. Embedded processors in CPS field devices often possess little security of their own, and are easily exploited once the network is penetrated. We identify four possible outcomes of a cyber-attack on a CPS embedded processor. We then discuss five trust requirements that a device must satisfy to guarantee correct behavior through the device´s lifecycle. Next, we examine the Trustworthy Autonomic Interface Guardian Architecture (TAIGA) which monitors communication between the embedded controller and physical process. This autonomic architecture provides the physical process with a last line of defense against cyber-attacks. TAIGA switches process control to a trusted backup controller if an attack causes a system specification violation. We conclude with experimental results of an implementation of TAIGA on a hazardous cargo-carrying robot.
