Preventing and handling API breaches

Why API security matters

API breaches can cripple organizations, leading to:

  • Sensitive data leaks (customer PII, financial records)

  • Reputational damage and loss of trust

  • Regulatory fines (GDPR, CCPA, HIPAA violations)

  • Service disruptions from attacks like DDoS or data corruption

API security checklist

Authentication

  • Enforce MFA for admin endpoints

  • Use short-lived JWT tokens (30min expiry)

Data Handling

  • Mask sensitive fields (SSNs, passwords) in logs

  • Rate limit by IP/user (prevent brute force)

Infrastructure

  • WAF rules for API endpoints (block SQLi/XSS)

  • Regular secret rotation (API keys, DB creds)

Incident response plan

Have a playbook for:

  • Token revocation

  • False positive handling

  • Breach disclosure timelines
