RF-RADS: A Robust Framework for Risk Assessment in Digital Substations
Bibliographic record
Abstract
The integration of Information and Communication Technology (ICT) into Smart Grids has revolutionized the efficiency and functionality of power systems. However, this advancement has also introduced significant cybersecurity challenges. Among the most vulnerable components are digital substations, which serve as critical hubs in power distribution and are susceptible to cyberattacks that can trigger cascading failures and widespread disruptions. This paper presents a structured procedure for risk assessment, emphasizing system analysis, dependency evaluation, and asset profiling based on their vulnerability to potential adversarial techniques. Prioritizing risks facilitates targeted and effective post-attack mitigation strategies, ensuring faster recovery, reduced impact, and minimized downtime following an attack. Using the MITRE ICS ATT&CK Framework, we systematically identify adversarial techniques and assess the criticality of substation components. Different substation devices attract specific attack techniques depending on their role and exposure in the system; the MITRE ICS framework helps map these patterns to enable focused and effective defense. With a clear understanding of system structure and threats, we can develop mitigation solutions tailored to specific needs. RF-RADS generates a quantified risk profile by scoring substation assets, enabling systematic identification of critical components, with control servers, workstations, and data gateways identified as the highest-risk assets.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
