Real-world case studies for a process-aware IDS

Area of Science:

• Cybersecurity
• Energy Systems Engineering
• Network Security

Background:

• Sustainable energy transitions depend on reliable communication infrastructure.
• Supervisory Control and Data Acquisition (SCADA) networks are vital for energy distribution but face cyber-attack vulnerabilities.
• Existing Intrusion Detection Systems (IDS) for SCADA networks are often tested only in simulations.

Purpose of the Study:

• To present real-world case studies of a process-aware IDS for SCADA networks.
• To demonstrate the effectiveness of tailored IDS solutions in detecting cyber-attacks on critical grid infrastructure.
• To advocate for the transition from simulation-based testing to real-world validation for SCADA security.

Main Methods:

• Developed and deployed a process-aware Intrusion Detection System (IDS).
• Conducted two real-world case studies using actual grid data.
• Tailored the IDS solution to specific SCADA network topologies.

Main Results:

• The process-aware IDS effectively detected various cyber-attacks.
• Specific attacks targeting critical grid devices, such as transformers, were successfully identified.
• The solution demonstrated practical applicability beyond simulated environments.

Conclusions:

• Real-world validation is crucial for ensuring the safety and reliability of critical grid infrastructure.
• A gradual transition from simulation to real-world testing is necessary for practical IDS deployment.
• Tailored, process-aware IDS solutions offer enhanced security for SCADA networks.
