Security Analysis and Auditing of IEC61850-Based Automated Substations
Bibliographic record
Abstract
This paper proposes a scheme for auditing the security of an IEC61850-based network based upon a novel security metric for intelligent electronic devices (IEDs). A detailed security analysis on an IEC61850 automated substation is peformed initially with a focus on the possible goals of the attacker. This is followed by the development of a scheme to audit the security of such a network. Security metrics are considered since they provide a tangible means of quantifying the security of a network. The proposed auditing scheme is tested by using it to audit the security of an IEC61850 network. The results are then compared with two other metric schemes-the mean time to compromise (MTTC) metric and the VEA-bility metric, which are used for auditing conventional computer networks. The input data for both metrics are obtained by using a network security tool to scan the IEDs of the network. The impact of using high-traffic generating network security tools on a time-critical IEC61850 network is also investigated.

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.
