Real-time Systems (RTS) are everywhere. Embedded RTS are used for monitoring and controlling physical systems and processes in varied domains, including Unmanned Aerial Vehicles (UAVs), critical infrastructures (e.g., power grids and water systems), industrial plants, medical devices to name but a few. However, until recently, cyber-security considerations were an afterthought in the design of such systems. Due to the use of component-based subsystems from different vendors as well as increased connectivity through unreliable media such as the Internet, modern RTS are exposed to unknown security flaws. Threats to RTS are growing, both in number as well as sophistication, as demonstrated by recent attacks on UAVs, automobiles, and industrial control systems. A successful attack on systems with real-time properties can have disastrous effects from loss of human life to damage to the equipment and/or the environment.
It is not straightforward to integrate of security mechanisms without compromising the safety and predictability guarantees of such systems. In this talk, I will present the approaches to integrate security mechanisms into RTS (especially legacy RTS) and introduce a metric to measure the effectiveness of such integration. I will illustrate our proposal that combines the opportunistic execution with hierarchical scheduling to maintain compatibility with legacy systems while still providing flexibility.
Monowar Hasan (http://web.engr.illinois.edu/~mhasan11/index_org.html) is working towards his Ph.D. in the Department of Computer Science, University of Illinois Urbana–Champaign, Urbana, IL, USA. His research in the intersection of Security and Systems/Networking (real-time/cyber-physical systems, wireless and software defined networks). Hasan received his M.Sc. degree in the Department of Electrical and Computer Engineering, University of Manitoba, Winnipeg, MB, Canada, in 2015, and the B.Sc. degree in computer science and engineering from Bangladesh University of Engineering and Technology (BUET), Dhaka, Bangladesh, in 2012.
