Development of a Decision Support System for Cyber-Incident Response in Smart Grids: Evaluating the Impact of Decision-Making Algorithms

February 3rd, 2025

With the increasing complexity of industrial control systems (ICS) in smart grids, the risk of cyber-attacks is also rising. To enhance the security and resilience of these systems, new approaches are needed for detecting and mitigating cyber incidents. This thesis develops a decision support system (DSS) designed to assess and recommend effective countermeasures against cyber threats in smart grids. The DSS incorporates various decision-making methodologies to evaluate and prioritize response strategies. By leveraging a co-simulated environment, the system enables realistic scenario testing, ensuring a comprehensive assessment of different countermeasures. The impact of various decision-making techniques will be analyzed and compared to existing response playbooks, providing insights into optimizing cyber resilience in smart grids.

The thesis is structured into four key phases:

  1. Data Collection
    • Familiarization with the CoSim Project and its incident response workflow.
    • Integration with the MITRE ATT&CK framework API to retrieve relevant threat and countermeasure data.
    • Collection of countermeasure properties for evaluation.
  2. System Development
    • Implementation of a data management system to structure and process cyber incident data.
    • Development of a decision management system that applies multi-criteria decision-making methods to evaluate countermeasures.
    • Creation of a user interface system that visualizes decision outputs in attack-defense trees.
  3. Evaluation
    • Analysis of the impact of different decision-making methodologies on the effectiveness of the DSS.
    • Benchmarking system performance against existing cybersecurity playbooks.
  4. Thesis Documentation
    • Ongoing documentation of findings and methodology throughout the research process.
    • Finalization of the thesis, including results interpretation, discussions, and conclusions.
