Best Practices for Secure Federation

Welcome! In this lesson, we'll explore industry best practices for building secure and resilient Micro Frontend (MFE) systems.

While MFEs offer great flexibility, they also introduce new security considerations. Applying these practices helps protect your applications and users.

The Principle of Least Privilege (PoLP) dictates that each MFE, service, or user should only have the minimum permissions necessary to perform its function.

• Limit API Access: Ensure MFEs only call APIs they absolutely need.
• Scoped Permissions: Grant specific permissions instead of broad ones.
• User Roles: Tie MFE access to granular user roles.

This minimizes the damage if one MFE is compromised.
