  • Process-Aware Cyberattacks for Thermal Desalination Plants
    Center for Cyber Security, NYUAD
    • Performed process-aware security assessment of desalination plants to identify attack entry points, categorize the attacks, estimate the corresponding financial loss, and mechanical damage.
    • Computed the resultant thermal shocks and pressure surges during water hammer in the piping system on sudden valve closure in MATLAB.
    • Quantified the detrimental effects of water hammering during such attacks in terms of Maximum induced von Mises stresses (340 MPa) and maximum displacement (19.94mm) with ANSYS.
