APIs connect modern software systems, but security gaps can lead to serious breaches. This post outlines key strategies to protect your APIs.

Common API Vulnerabilities

APIs often suffer from authentication flaws, excessive data exposure, and injection risks.

Understanding these vulnerabilities is the first step to effective mitigation.

Authentication and Authorization

Robust authentication methods like OAuth 2.0 protect APIs from unauthorized use.

Role-based access controls ensure clients only access permitted resources.

Rate Limiting and Throttling

Limiting the number of requests guards against abuse and denial-of-service attacks.

Implementing throttling policies protects backend systems and maintains service availability.

Regular Security Testing

Penetration testing and vulnerability scanning catch weaknesses before attackers do.

Continuous testing should be embedded into the development lifecycle.
