Georgios Michail Makrakis (a.k.a George Makrakis) main interests are Cybersecurity and Software Engineering especially on Industrial Internet of Thins (IIoT). Currently works as OT Security Consultant at Hudson Cybertec \ Kiwa NL. Holds commercial experience as Cybersecurity Researcher and Software Engineer. Has proven ability to prioritize tasks, collaborate with external parties, and design robust solutions. Graduated from the University of the Aegean with an Integrated Master’s in Information & Communication Systems Engineering specializing in cybersecurity and software engineering, and owns a Doctorate (Ph.D.) in Computer Science from University of Idaho.
Joined Plegma Labs as a member of the University's internship program, specialized on software development. Also provided DevOps solutions and had IoT security, as basic guideline in every project.
Developed networking capabilities and cyberattack scenarios for nuclear power plant simulators that serve the purpose of evaluating the operators' responses against threats that can affect digital technologies in modern nuclear power plants.
Examined the effects that logic modification and network attacks have to the physical properties of ICSs/IoT devices using electromagnetic (EM) emissions analysis. Also, incorporated a secure-by-design architecture for Smart Grid applications based on IEC 62443.
Delivered specialized expertise in ICS/OT network security, with a focus on maritime cybersecurity through applied research and stakeholder collaboration. Engaged into the development of a maritime-focused honeynet, and attacks/defenses of radar protocols, and the maintenance and enhancement of the Maritime Cyber Attack Database (MCAD).
Assessing and improving the cybersecurity of Industrial Control Systems (ICS)/ Operational Technology (OT) environments. Consulting customers in various industrial sectors and supporting them in implementing security solutions that meet global security standards such as ISO 27001 and IEC 62443.
Research area: Proactive and reactive security for ICS/OT with the use of EM emissions analysis and Software-Defined Networking
First 3 years studied the fundamentals of ICT for the bachelor and the next 2 followed Security of Information and Communication Systems and Privacy, Communication Systems and Networks and Foundations of Computer Science as my technological directions of studies to receive the integrated master.
Member of Microsoft Student Partners, a group under the auspices of Microsoft with mission to encourage students to participate in their local tech community and develop valuable technical, and career skills that will be beneficial for their future careers.
