Structure Refinement for Vulnerability Estimation Models using Genetic Algorithm Based Model Generato

In this paper, a method for model structure refinement is proposed and applied in estimationof cumulative number of vulnerabilities according to time. Security as a quality characteristicis presented and defined. Vulnerabilities are defined and their importance is assessed. Existingmodels used for number of vulnerabilities estimation are enumerated, inspecting theirstructure. The principles of genetic model generators are inspected. Model structure refinementis defined in comparison with model refinement and a method for model structure refinementis proposed. A case study shows how the method is applied and the obtained results
