Defect taxonomies are categorized lists of defects that can be used to identify and prevent common types of errors in software development and testing. They can also be used to design test cases that target specific defect types, such as security vulnerabilities. Therefore, using a list of known defect types to penetrate the security of computer systems is an example of the use of defect taxonomies. References = Defect Taxonomies - The Practical Guide to Defect Prevention (Chapter 10), Using Defect Taxonomies for Testing Requirements, Defect Based Approach using Defect Taxonomy, Requirements-based testing with defect taxonomies
