In this talk, Dr. Rush outlines how cyber attacks against critical infrastructure can impact the supply of gas, water, and electric grids. Cyber-attacks are usually thought of as directed against information, such as compromise of passwords, access to financial information, or theft of information. The focus of this talk is on the need to increase the level of protection on critical infrastructure. The issue is viewed from the attacker’s point of view and outlines the physical impacts of a successful attack. This event is part of the STEM lecture series.
