The 10 most critical API security risks - Part 7: Security Misconfiguration

The recently published “OWASP API security top 10” report analyzes the anti-patterns that lead to vulnerabilities and security risks in APIs. In this 10 part series, we introduce these API anti-patterns. Every API professional should know about these anti-patterns. In this blog post, we focus on “API security misconfiguration”.

API security anti-pattern for Security Misconfiguration

Security misconfiguration is commonly a result of insecure default configurations, incomplete or ad-hoc configurations, open cloud storage, misconfigured HTTP headers, unnecessary HTTP methods, permissive Cross-Origin resource sharing (CORS), and verbose error messages containing sensitive information.

The good thing is, that it is relatively easy to fix security misconfiguration and considerably improve the API security as a result.
