Input validation is a programming technique that ensures only properly formatted data may enter a software system component. This is one of the OWASP Top 10 Proactive Controls (2024 edition), the OWASP Foundation's list of the ten most important security techniques that every software architect and developer should build into every project. Where the OWASP Top 10 enumerates the most critical web application security risks, the Proactive Controls enumerate the defensive techniques that prevent them. Organizations should treat this control as a design requirement, an implementation checklist, and a continuous-verification obligation, supported by a security policy, automated testing in the CI/CD pipeline, developer training, and incident response.",
