Park, Kyuchan, Ahn, Bohyun, Kim, Jinsan, Won, Dongjun, Noh, Youngtae, Choi, JinChun, Kim, Taesic.  2021.  An Advanced Persistent Threat (APT)-Style Cyberattack Testbed for Distributed Energy Resources (DER). 2021 IEEE Design Methodologies Conference (DMC). :1–5.
Advanced Persistent Threat (APT) is a professional stealthy threat actor who uses continuous and sophisticated attack techniques which have not been well mitigated by existing defense strategies. This paper proposes an APT-style cyber-attack tested for distributed energy resources (DER) in cyber-physical environments. The proposed security testbed consists of: 1) a real-time DER simulator; 2) a real-time cyber system using real network systems and a server; and 3) penetration testing tools generating APT-style attacks as cyber events. Moreover, this paper provides a cyber kill chain model for a DER system based on a latest MITRE’s cyber kill chain model to model possible attack stages. Several real cyber-attacks are created and their impacts in a DER system are provided to validate the feasibility of the proposed security testbed for DER systems.
