Towards Incorporating Discrete-Event Systems in Secure Software Development
Bibliographic record
Abstract
When designers and developers create software they often overlook issues related to security. Ideally, protection of the program from illegal usage would be considered at each stage of this program's life cycle. The proposition put forward here is to augment intrusion detection systems (IDSs) and employ them as a tool to support secure software development. Many state-based intrusion detection methods share structural and behavioural similarities with the set of processes known as discrete-event systems (DESs). A common structure for modelling DESs is the deterministic finite-state automaton. There exist several compatible anomaly detection techniques which construct finite- state machine models of normal behaviour through the decomposition of associated data (e.g., system calls, HTTP requests) into sequences of events. This paper proposes the application of decentralized DES theory to formally analyze and enhance these approaches to anomaly detection with misuse prevention. Models of misuse attacks are generated in the same manner as the legal usage representation, then augmented and integrated into the program model to prevent the execution of malicious sequences. The technique described herein simultaneously uses anomaly and misuse approaches to prevent and disable attacks before their completion.

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.
