On detecting and clustering distributed cyber scanning
Bibliographic record
Abstract
This paper proposes an approach that is composed of two techniques that respectively tackle the issues of detecting corporate cyber scanning and clustering distributed reconnaissance activity. The first employed technique is based on a non-attribution anomaly detection approach that focuses on what is being scanned rather than who is performing the scanning. The second technique adopts a statistical time series approach that is rendered by observing the correlation status of a traffic signal to perform the identification and clustering. To empirically validate both techniques, we experiment with two real network traffic datasets and implement two proof-of-concept environments. The first dataset comprises of unsolicited one-way telescope/darknet traffic while the second dataset has been captured in our lab through a customized setup. The results show, on one hand, that for a class C network with 250 active hosts and 5 monitored servers, the proposed detection technique's training period required a stabilization time of less than 1 second and a state memory of 80 bytes. Moreover, in comparison with Snort's sfPortscan technique, it was able to detect 4215 unique scans and yielded zero false negative. On the other hand, the proposed clustering technique is able to correctly identify and cluster the scanning machines with high accuracy even in the presence of legitimate traffic.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
