What is the OWASP API Top 10?
The OWASP API Security Top 10 is a list of the most critical API security risks. It helps organizations understand vulnerabilities specific to APIs, including broken authentication, injection attacks, and improper data exposure.
Why Scan Your APIs?
APIs are the backbone of modern applications but are often overlooked in security testing. Regular scanning helps identify misconfigurations, authentication flaws, and data exposure risks before attackers can exploit them.
Key Security Headers
Content-Security-Policy- Prevents XSS attacksX-Content-Type-Options- Prevents MIME sniffingStrict-Transport-Security- Enforces HTTPS
JWT Best Practices
- Always validate token signatures
- Use short expiration times (< 1 hour)
- Store sensitive data outside the token payload
- Use RS256 over HS256 for better key management
