Evaluating the Resilience of Software Architecture Based on Minimal Path

The resilience of a software architecture plays a vital role in the security of a software system, and poor resilience in a software architecture translates to the insecurity of the software system. However, achieving effective quantification of resilience in software engineering is a challenging problem during the system architecture construction stage. Although some methods have been proposed to evaluate the resilience of software systems with the development of resilience security theory, existing methods have shortcomings, such as the lack of connotation of evaluation metrics and overly large time complexity, which lead to limited applications for resilience evaluation in software architecture.To bridge this gap, we propose a software architecture resilience evaluation method based on the minimal path. Starting from the activity diagram, we construct a minimal path set to divide the system missions and build a state-conversion model that quantifies resilience metrics and calculates resilience evaluation results. Additionally, we compare our method with three other evaluation methods for architecture resilience, analyze the factors that affect software architecture resilience, and validate the effectiveness of our method.
