Insecure Design Definition: Insecure Design is OWASP Top 10 2021 A04, covering architectural security flaws from missing threat modeling and secure design patterns, not just coding bugs.
Insecure Design is a category introduced as A04 in the OWASP Top 10 2021 that addresses risks stemming from missing or ineffective security controls at the architecture and design stage, distinct from implementation bugs. It captures failures to apply threat modeling, secure design patterns, and reference architectures, meaning a perfectly coded system can remain vulnerable because the design itself never accounted for the threat. Remediation emphasizes shifting security left through threat modeling, secure design principles, and validating business-logic flows before code is written.
