Phd Position: Vulnerability search in Industrial Control Systems

A reverse engineering approach

 SUBJECT DESCRIPTION

Industrial control systems are specialized computer systems used in many activities of vital importance like energy production and distribution, chemical industry or water management. These systems consist in dedicated hardware and software (PLCs, Control Systems, IHM) interacting via field-bus communications. Their components and communication protocols are often based on legacy and out-of-date hardware and software, not always in conformity with modern security standards and updates. Thus, they might include vulnerabilities which may be used by attackers with potentially serious consequences. Vulnerability research and analysis are then a major concern for governmental agencies (ANSSI), component providers, and end-users. The topic of this PhD lays in this field, dealing with vulnerability detection in industrial systems. Due to the unavailability of both the complete specifications and the source code of the software components, we propose a reverse engineering approach for vulnerability detection. This approach may target several layers like:

  • Behavioral inference of the control automaton of a PLC via active learning (observing the input/output dependencies), considering first autonomous automata and then studying the extension to timed and/or hybrid automata;
  • Code analysis of the embedded PLC software, namely the operation blocks and/or the communication layer implementations, combining static and dynamic analysis of binary code and execution traces. The main objective is to discover abnormal or unexpected behaviors that may be exploited by an attacker to modify or disrupt the physical process. This study will be hosted by research teams CTRL-A (LIG) and PACS (Verimag), which hold strong knowledge in industrial systems analysis, reverse engineering and code analysis techniques. Financial grant supported by Cross Disciplinary Project Grenoble Alpes Cybersecurity Institute part of University Grenoble-Alpes IdEx.
