Introduction to API08:2023 Security Misconfiguration
Security Misconfiguration refers to improperly configured security settings in APIs or their infrastructure. This includes overly verbose error messages, default credentials, unnecessary HTTP methods, misconfigured CORS policies, exposed admin panels, or lack of secure headers. Such misconfigurations can give attackers valuable information or unintended access. They often result from default settings, rushed deployments, or lack of security reviews. To prevent this, enforce a secure-by-default configuration, disable unnecessary features, regularly audit and harden settings, and automate security testing. APIs should be deployed with the minimum necessary access and regularly reviewed for gaps in configuration or exposure.
