Abstract
This article presents a hybrid architecture to identify intrusive behavior among networked sensors that monitor critical systems such as environment, medical, and smart grid. Monitoring through sensors is desired for critical applications such as epilepsy seizures, pollution, power quality assessment, and transformer monitoring. Wireless sensors are being widely used in critical applications due to their advantages including low-cost, flexibility, and communication efficiency. However, when sensors are networked to monitor a critical infrastructure such as the smart grid, they become the target of different types of attackers such as intruders via the communication medium. In order to maintain sensing in a secure manner, robust architectures are needed to identify intrusive behavior of sensors in a network. In this article, we present a hybrid architecture to detect intrusive behavior of sensors for both unknown and known intruders. The former requires anomaly detection, whereas the latter requires signature detection. The proposed architecture consists of two subsystems that co-operate to detect unknown and known attacks through duty-cycling of enhanced density-based spatial clustering of applications with noise and random forest methods. Through various tests on real intrusion data, we show that the proposed architecture has a strong potential to detect both known and unknown intrusive behavior of sensor nodes as the results show 99.73% detection rate with 98.95% overall accuracy.

Full frame distilled prediction
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
