Security Threat Modeling for Power Transformers Cyber-Physical Environments

Due to the efforts of digitization of power grids and integration of online diagnosis systems, today's power transformers have been promoted to deploy seamless contaminations and information technology-, which potentially presents growing threats from cycler-attacks. This paper provides security vulnerabilities and potential threats of power transformers in cyber-physical environments through a security threat modeling methodology. The proposed seem sty threat modeling includes three steps: 1) system identification, 2) threat modeling, 3) and attack modeling. The devised security threat model can identify potential vulnerabilities and threats as well as simulate attack success rate, which will be used to develop device-level defense strategies to protect pon'er transformers from malicious cyber-attacks, ensuring the secure utilization of the cyber physical power transformers in modern power infrastructures.
