About Vulnerability Classification

Understanding vulnerability types is crucial for effective security testing, incident response, and risk assessment. Each vulnerability class has unique characteristics, exploitation methods, and mitigation strategies.

Trace Within classifies vulnerabilities based on the type of attack they enable, following industry-standard taxonomies like CWE (Common Weakness Enumeration) and OWASP classifications.
