Security concerns in the energy sector will be our key driver and the smart grid technology will be our primary focus in the research and the investigation related to physical and cyber security issues. Many challenges have emerged and are facing this sector and we need to ensure that threats are being investigated and tolerated with proper detection and mitigation mechanism.

520 $a Security concerns in the energy sector will be our key driver and the smart grid technology will be our primary focus in the research and the investigation related to physical and cyber security issues. Many challenges have emerged and are facing this sector and we need to ensure that threats are being investigated and tolerated with proper detection and mitigation mechanism.
520 $a The title of the PhD thesis is "Smart Grid DNP3 Cyber Attack Detection and Mitigation Strategies". The research approach in this dissertation consisted of performing preliminary studies and investigation of critical infrastructure involving the energy sector and the smart grids followed by three primary phases. In the first phase, potential vulnerabilities associated with smart grid implementations were identified involving major communication protocols including DNP3, DNP3-SA, IEC-61850 and Modbus primarily used in SCADA environment.
520 $a Smart grid using DNP3 protocol was modeled in the second phase using virtual lab environment and DETER testbed in order to evaluate specific cyber security threats and vulnerabilities. Analyzing vulnerabilities and performing penetration testing to identify possible threats led to the final phase to overcome the threats by developing mitigation strategies and techniques. Mitigation algorithms were formulated and add-on software utilities and tools were developed in C++ and other programming environment to enhance the DNP3 protocol standard and to facilitate host based Intrusion Detection System (HIDS) mechanism.
520 $a The PhD dissertation investigated the impact, detection, and mitigation of various attacks scenarios on smart grid infrastructure. Man-In-The-Middle (MITM) attacks were explored and modeled using game theory analysis and techniques and Nash equilibria was utilized to highlight possible outcomes and to prove the pass and drop strategy effectively used in detection and mitigation. We established an observation model based on the Round Trip Time Delay (RTTD) for each DNP3 round trip transaction. Likelihood distributions for both legitimate and hacked transactions were simulated in MATLAB. Bayesian analysis and both Maximum a Posterior probability (MAP) and the loss functions were used to optimize our detection threshold to ensure high level of attack detection accuracy. Our novel threshold optimization approach is unique and the optimization is updated dynamically in real time.
