Common API Security Mistakes and How to Avoid Them

Introduction: APIs Fail Not by Code, But by Oversight

API breaches often occur not because of malicious code, but due to misconfigurations, overexposed endpoints, and weak visibility. Let’s break down recurring mistakes that developers can easily prevent.

1. Missing Rate Limits

No limits mean open abuse. Always enforce per-user and per-IP throttles. APIGate provides configurable rate limiting per minute, hour, or day, helping contain damage preemptively.

2. Ignoring Response Patterns

Sequential 4xxs or 5xx spikes may indicate automated exploitation attempts. APIGate’s anomaly detection monitors such patterns per identity, triggering mitigation without manual review.

3. Weak Access Controls

Never rely solely on app-level authentication—enforce contextual verification such as geo checks and IP restrictions. APIGate’s decision API normalizes access validation automatically before backend processing.

4. Delayed Threat Awareness

Discovering abuse hours after it happens is already a breach. Real-time monitoring shortens reaction times; APIGate’s low-latency analytics enable immediate visibility.

Conclusion

Preventing API breaches is mainly about foresight and automation. Solutions like APIGate take care of both—proactively identifying abnormalities while keeping your service fast and reliable.
