Introduction to Cyber-Physical Systems Security

Speaker:  Alireza Jolfaei – Sydney, NSW, Australia
Topic(s):  Security and Privacy


Cyber-physical systems (CPS) comprise the backbone of national critical infrastructure such as power grids, transportation systems, and home automation systems, which are highly interconnected and mutually dependent systems. Such systems support a diverse set of services using a wide variety of Internet of Things (IoT) devices for sensing and actuation. The actions initiated by the service controllers could occasionally lead to conflicts or undesirable, unsafe outcomes both due to inadvertent misconfiguration, attacks on the configuration state, and poorly understood dependencies. From consumer IoT devices developed with minimal built-in security, which are often co-opted by malware to launch large distributed denial of service attacks on internet infrastructure, to remote attacks on industrial control devices, these newly connected, composed systems provide a vast attack surface. To this end, more secure configurations should be developed to address system vulnerabilities and minimize attack surfaces while maintaining expected functionality and performance. 

This talk covers relevant concepts, the state-of-the-art, representative solutions, and open challenges in CPS security. During the lecture, we will discuss different types of attack scenarios on the sensing and cyber parts of CPS with recent examples from intelligent transportation and power systems. We will next discuss the theoretical aspects and analysis of different mitigation strategies to secure the system from adversarial perturbations. We will compare and contrast the mitigation techniques and discuss their strengths and weaknesses. Finally, we will describe the practical implementation of each of the algorithms along with future challenges.
