BF bugs models, multidimensional weakness and failure taxonomies, and vulnerability models define the lexis, syntax, and semantics of the BF formal language and form the basis for the definition of secure coding principles. The BF formalism supports a deeper understanding of vulnerabilities as chains of weaknesses that adhere to strict causation, propagation, and composition rules. It enables the generation of comprehensively labeled weakness and vulnerability datasets and multidimensional vulnerability classifications. It also enables the development of new algorithms for code analysis and the use of AI models and formal methods to identify bugs and detect, analyze, prioritize, and resolve or mitigate vulnerabilities.
