A distributed system is a system whose components are located on different networked entities (e.g., computers, sensors) that communicate and coordinate their actions by exchanging messages. These entities have a shared state, operate concurrently and can fail independently without affecting the whole system’s uptime. With the ever-growing technological expansion of the world, distributed systems are becoming more and more widespread.
In past years, I have addressed the protection and resilience of distributed systems such as Clouds, Data Centres, Mobile Agent and Actuator Networks, Vehicular and Wireless Sensor Networks. Building on this expertise, in the medium term, I plan to address various cyber security issues and develop attack resilient solutions for a very important type of distributed systems, namely the industrial automated control systems and networks that are monitoring and controlling the operation of critical infrastructures in different sectors. These include the Energy sector (e.g., oil pipelines, nuclear plants), the Financial sector, Government Operations, Water Supply, Health Systems and more. Cyberattacks against critical infrastructures have increased significantly in the last decade and caused serious damage with very important social and economic losses. However, research on protecting the control systems of critical infrastructures against cyberattacks is still at an early stage and faces many open technical challenges.
