Cyber Physical systems (CPS) are composed of a computing base and a physical process to be controlled. Few examples include, medical devices e.g. pace makers, networked control systems e.g. smart grid, water treatment plants etc., critical infrastructures e.g. urban transportation, air traffic control etc. Legacy systems had proprietary protocols and system specific hardware and software solutions but current CPS rely on generic solutions to be scalable as well as less costly. These connected systems are easy to monitor and control on one hand but on the other give rise to many technical and non-technical challenges. Security of CPS is one such challenge. CPS security is different from pure cyber systems in a sense that threat models are quite different. Now attacks not only can be launched from the cyber component but also physical attacks are possible e.g. removing, adding or manipulating a hardware component. Earlier if a computer system got hacked, the potential loss would be of information and monetary but if a CPS is compromised results could be catastrophic resulting in loss of information, money, life, infrastructure and environmental hazards. One well know example is of ‘stuxnet worm’ which compromised Iran’s nuclear plants in 2010. The unique challenge in protecting the CPS infrastructures is that protocols should be designed as such, which should not affect the process itself. Attack detection and mitigation should be performed without affecting the functionality of the plant as well as reducing efficiency. To this end, in this talk, we will look into control theoretic perspective of achieving the goal of security in CPS.
