Cybersecurity Lecture Series with Sakis Meliopoulos

Energy System Cybersecurity and Operational Reliability

The electric energy grid is recognized as critical infrastructure. It is vulnerable to self-disturbances as well as cyberattacks. In particular, cyberattacks can cause mild disruptions or serious damage that may take years to repair -- posing a serious threat to security of the nation. This talk will present the cyber-physical infrastructure of the electric energy grid and the existing vulnerabilities. We will discuss vulnerability scenarios, activities at the power industry sector to harden the system against cyberattacks, and recent research to detect cyberattacks in real time. We present an infrastructure that enables simultaneous cybersecurity and operational security. The approach monitors the dynamic state of the power system and leverages this knowledge to detect (a) data attacks and (b) detriments to the system commands (that may originate from a malicious attacker or by operator error). The overall intrusion detection system is loaded to the existing cyber infrastructure at the substations of the electric power grid. It is a distributed system and therefore it is scalable to any size electric energy grid. 

A.P. "Sakis" Meliopoulos, Ph.D., is an associate director of the Institute for Information Security & Privacy (IISP) for the area of cyber-physical systems research, and is the Georgia Power Distinguished Professor in the School of Electrical & Computer Engineering at Georgia Tech. Meliopoulos helped the development of the power program at Georgia Tech by contributing to the modernization of existing courses, introducing new courses, initiating research activities, and developing continuing education programs and the Power System Certificate program.


The Cybersecurity Lecture Series at Georgia Tech is a free, one-hour lecture from a thought leader who is advancing the field of information security and privacy. Invited speakers include executives and researchers from Fortune 500 companies, federal intelligence agencies, start-ups and incubators, as well as Georgia Tech faculty and students presenting their research. Lectures are open to all -- students, faculty, industry, government, or simply the curious.
