APIs expose application logic and data, making them prime targets for attackers seeking to exploit vulnerabilities or abuse functionality.
API Threats
- Broken Authentication - Weak or missing authentication controls.
- Injection Attacks - SQL, NoSQL, and command injection via API inputs.
- Rate Limit Bypass - Evading controls to abuse API resources.
Security Essentials
- Authentication & Authorization - Use OAuth 2.0 or API keys with proper scoping.
- Input Validation - Validate and sanitize all API inputs.
- IP Reputation - Block or rate limit suspicious IP sources.
Conclusion
API security is critical as APIs become the primary interface for modern applications. By implementing strong authentication, input validation, and IP reputation checks, you can protect your APIs from abuse and attacks.
