S. (Saba) Chockalingam
Saba Chockalingam is a PhD candidate at the Faculty of Technology, Policy, and Management in the Safety and Security Science section. He works on the project entitled “Secure Our Safety: Building Cyber Security for Flood Management (SOS4Flood)”.
Saba received his Bachelor of Technology (B.Tech) in Computer Science and Engineering from SRM University (India) in 2012, and his Master of Science (MSc) in Cyber Security and Management from the University of Warwick (England) in 2014. During his MSc, he worked on the thesis entitled “Enriching Social Media Sites (SMS) Data with Geographic Intelligence”.
Today's society depends on the seamless operation of Critical Infrastructures (CIs) in different sectors such as energy, transportation, and water management, which is essential to the success of modern economies. Over the years, CIs have heavily relied on Industrial Control Systems (ICS) to ensure efficient operations, which are responsible for monitoring and steering industrial processes as, among others, water treatment and distribution, and flood control.
Because of modern societies' dependence on ICS, adequate response to system failures is essential. In order to take appropriate measures, it is crucial for operators to be able to distinguish between intentional attacks and accidental technical failures. However, adequate decision support for this matter is lacking. My research aims to fill this gap by utilizing Bayesian Networks (BNs) which has been widely employed in real-world applications especially in medical diagnosis and fault diagnosis. Although the scope of my study is focused on water management systems operated by ICS, the developed integrated BN model may be applied to the other CIs operated by ICS.
