OWASP Top 10 (OWASP Top 10)

Security Glossary - Web Security

Definition: The OWASP Top 10 is a widely referenced standard awareness document listing the ten most critical web application security risks. Published by the Open Web Application Security Project, it is updated every few years based on vulnerability data from hundreds of organizations. The current version (2021) includes broken access control, cryptographic failures, injection, insecure design, and security misconfiguration.

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 2021 Top 10 includes: A01 Broken Access Control, A02 Cryptographic Failures, A03 Injection (SQL, NoSQL, OS, LDAP), A04 Insecure Design, A05 Security Misconfiguration, A06 Vulnerable and Outdated Components, A07 Identification and Authentication Failures, A08 Software and Data Integrity Failures, A09 Security Logging and Monitoring Failures, A10 Server-Side Request Forgery.

For indie hackers 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

A security audit checks for several OWASP Top 10 issues including security misconfiguration (missing headers), cryptographic failures (weak TLS), and exposed components. For full OWASP Top 10 coverage, combine automated scanning with manual security review.

OWASP Top 10 FAQ

How often is the OWASP Top 10 updated?
Approximately every 3-4 years. The current version was published in 2021. Updates reflect shifts in real-world attack patterns and are based on vulnerability data contributed by organizations worldwide.
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.
