How to Secure a Headless CMS
IntermediateQuick Answer
TL;DR
Securing a headless CMS means focusing on API security, access control, and data protection. Use API tokens scoped to the minimum required permissions, configure CORS to restrict which domains can call your API, enforce HTTPS for all API communication, implement role-based access control (RBAC) for editors, enable two-factor authentication, and monitor API usage for anomalies. The attack surface is inherently smaller than traditional CMS platforms — there's no public admin panel — but API security requires deliberate configuration.
Key Takeaways
- Use read-only API tokens for public content delivery; restrict write tokens to server-side processes only
- Configure CORS to allow API access only from your authorized domains
- Apply least-privilege RBAC: editors should only access what their role requires
- Monitor API usage logs and set alerts for unusual request volumes or patterns
