OWASP Top 10 (OWASP Top 10)

Security Glossary - Web Security

Definition: The OWASP Top 10 is a widely referenced awareness document listing critical web application security risks. The current 2025 edition includes broken access control, security misconfiguration, software supply chain failures, cryptographic failures, injection, insecure design, authentication failures, integrity failures, logging and alerting failures, and mishandling exceptional conditions.

The Importance of OWASP Top 10

The OWASP Top 10 provides a prioritized starting point for web application security. It represents the consensus of the security community on which vulnerabilities are most common and most impactful. Many compliance frameworks, security standards, and audit requirements reference the OWASP Top 10.

The 2025 Top 10 includes: A01 Broken Access Control, A02 Security Misconfiguration, A03 Software Supply Chain Failures, A04 Cryptographic Failures, A05 Injection, A06 Insecure Design, A07 Authentication Failures, A08 Software or Data Integrity Failures, A09 Security Logging and Alerting Failures, and A10 Mishandling of Exceptional Conditions.

For builders and small teams, the most actionable items are: implement proper access controls, use parameterized queries (prevent injection), keep dependencies updated (vulnerable components), configure security headers (security misconfiguration), and use HTTPS everywhere (cryptographic failures).

How to Test for OWASP Top 10

DomainOptic covers a narrow external slice relevant to configuration, including TLS, selected headers, DNS email authentication, reputation signals, and public JavaScript patterns. It does not claim OWASP Top 10 coverage. Use code review, dependency analysis, authenticated testing, and manual security review for application risks.

OWASP Top 10 FAQ

How often is the OWASP Top 10 updated?
OWASP updates the list periodically rather than on a fixed annual schedule. The current edition was published in 2025 and reflects shifts in real-world risks and community input.
Is the OWASP Top 10 a compliance requirement?
Not directly, but many compliance frameworks (PCI DSS, SOC 2, HIPAA) reference it. Many organizations require that applications are tested against the OWASP Top 10 as part of their security assessment process.
