Real-Time Intrusion Detection in Network Traffic Using Adaptive and Auto-Scaling Stream Processor
Bibliographic record
Abstract
Advanced intrusion detection systems are beginning to utilize the power and flexibility offered by Complex Event Processing (CEP) engines. Adapting to new attacks and optimizing CEP rules are two challenges in this domain. Optimizing CEP rules requires a complete framework which can be ported to stream processors because a CEP rule cannot run without a stream processor. External dependencies of stream processors make CEP rule a black box which is hard to optimize. In this paper, we present a novel adaptive and functionally autoscaling stream processor: “Wisdom” with a built-in hybrid optimizer developed using Particle Swarm Optimization, and Bisection algorithms to optimize CEP rule parameters. We show that an adaptive “Wisdom” rule tuned by the proposed optimization algorithm is able to detect selected attacks in CICIDS 2017 dataset with an average precision of 99.98% and an average recall of 93.42% while processing over 2.5 million events per second. The proposed distributed functionally autoscaling deployment mode consumes significantly fewer system resources than the monolithic deployment of CEP rules.

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.
