Modelling Security Patterns Using NFR Analysis
Bibliographic record
Abstract
While many theoretical approaches to security engineering exist, they are often limited to systems of a certain complexity, and require security expertise that is not widely available. Additionally, in the practice of information system development security is but one of many concerns that needs to be addressed, and security concerns are often dealt with in an ad hoc manner. Security patterns promise to ?ll this gap. Patterns enable an ef?cient transfer of experience and skills. However, representing and selecting security patterns remains largely an empirical task. This becomes the more of a challenge as the number of security patterns documented in the literature grows, and as the patterns proposed by different authors often overlap in scope. Our contribution is to use a more explicit representation of the forces addressed by a pattern in the description of security patterns, which is based on non-functional requirements analysis. This representation helps us decide which patterns to ap-ply in a given design context, and anticipate the effect of using several patterns in combination. Speci?cally this chapter describes an approach for selecting security patterns, and exploring the impact of applying these patterns individually, and in concert with other patterns.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
