Traditional security evaluation of software focuses on detecting and patching known vulnerabilities. In this study, we propose evaluating security based on an antipattern approach, which shifts attention to broader architectural and coding practices. This methodology identifies common design or implementation patterns that may lead to security vulnerabilities. By recognizing and rectifying suboptimal practices, it aims to prevent security issues before they arise and encourages secure coding principles. This paper introduces the foundational framework for this innovative security assessment, highlighting its potential impact on software security.
