A cognitive multifractal approach to characterize complexity of non-stationary and malicious DNS data traffic using adaptive sliding window
Bibliographic record
Abstract
This paper presents a cognitive feature extraction model based on scaling and multifractal dimension trajectory to analyze internet traffic time series. DNS (Domain Naming System) traffic time series is considered that contains tagged DNS Denial of Service attacks. The first step of the analysis involves transforming the DNS time series into a multifractal variance dimension trajectory keeping statistical stationarity of data intact. Then features of the trajectory are extracted to remove high variability noise. The extracted set of features indicates the presence of an attack when the denoised trajectory shows increasing variance fractal dimension. This technique is superior in finding changing patterns of a data series due to the presence of noise and denial of service attack because it is not dependent on integer dimensions and mono-scale measurement of variations in data series. Moreover, this technique provides adaptive and locally stationary windows in a highly non stationary data series.

How this classification was reachedexpand
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.
