Cyber-Physical Systems

Impact

While harnessing cyber-physical systems could have enormous societal impact and economic benefit in many traditional industries, unique challenges are also presented as unexpected and abnormal systems behaviour can lead to disruptions which can have major impacts on society. 

Complex systems are difficult to build and manage and the extensive use of information and communication technologies in cyber-physical systems make them vulnerable to cyber attack. If the interface between complex systems components breaks down, the compromise can lead to a disruption ranging from small service interruptions to huge impacts on critical infrastructure such as transport or medical systems which could jeopardise physical safety and cause huge financial loss.   

Our research is developing innovative solutions and technological approaches to cyber-physical system design, management, and control which can be implemented in realistic and real cyber-physical systems environments to address CPS’s scalability, heterogeneity, security, timely intrusion detection, and complexity. This not only helps to mitigate cyber attacks but also provides a framework to ensure cyber-physical systems are resilient against potential threats.  

Research in Cyber-Physical Systems is closely linked with research into Resilient Infrastructure, Complex Systems Security, and Intelligent Security.
