Securing Your APIs: Best Practices for Modern Applications

API security is a layered effort that combines secure defaults, defensive coding, and runtime monitoring.

Core Controls

• Strong authentication and authorization policies.
• Input validation and schema enforcement.
• Rate limiting and abuse prevention.

Transport and Secrets

Always enforce HTTPS and rotate secrets on clear schedules. Keep credentials out of repositories and deploy logs.

Continuous Verification

Security posture should be measured continuously through logs, alerting, and periodic attack-surface reviews.
