Abstract
The move toward a smart power grid has widened the range of cyber vulnerabilities in supervisory control and data acquisition (SCADA) systems. Specialized security hardening devices, such as the trust systems, are being developed to protect energy SCADA networks from possible cyberattacks. The trust systems are network security resources that monitor and act on malicious packets. A node is said to be a trust node when it is equipped with a trust system. This paper investigates the optimal security deployment problem in resource-constrained SCADA networks. It proposes two deployment schemes for inline security devices: 1) link coverage maximization; and 2) minimal path tolerance (MPT). The first scheme focuses on the overall monitoring coverage. It is formulated as a quadratic assignment problem. The second scheme focuses on the hop distance between consecutive trust nodes. It uses a heuristic approach that deploys trust nodes in a distributive manner. The proposed schemes are evaluated considering the IEEE test case topologies under various scenarios. Numerical results demonstrate that the proposed schemes are capable of achieving their primary goals. They also reveal a performance tradeoff between the proposed schemes in the highly resource-constrained scenarios where MPT offers a better distributiveness.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
