API Security Best Practices: OWASP Top 10 for APIs > 자유게시판

API security requires addressing OWASP's top vulnerabilities. Object Level Authorization validates user access to . User A should not access User B's data through ID manipulation. Broken Authentication enables credential stuffing and token theft. Implement strong password policies and rate limiting. Excessive Data Exposure returns more data than needed. Filter response fields based on user permissions. Lack of Resources and Rate Limiting allows DoS attacks. Implement throttling per user and IP address. Broken Function Level Authorization ignores role-based access. Enforce authorization checks on every endpoint. Mass Assignment binds user input to model properties unexpectedly. Use DTOs and whitelist allowed fields. Security Misconfiguration includes default credentials and verbose errors. Automated scanning detects configuration issues. Injection flaws include SQL, NoSQL, and command injection. Parameterized queries prevent injection attacks. Improper Asset Management exposes forgotten API versions. Inventory and deprecate old endpoints properly. Insufficient Logging and Monitoring delays breach detection. Implement comprehensive logging and alerting. API security requires continuous attention and testing.
