Building Multi-Tenant APIs Using EF Core and Row-Level Security

Summary

The transcript discusses role-level security in PostgreSQL and .NET Core, focusing on implementing robust authorization checks for database applications. The demonstration involves using JSON web tokens, extracting user identifiers from claims, and ensuring that users can only access their own data through carefully designed API endpoints and database filters. The key practical takeaway is the importance of consistently applying user-specific authorization filters to prevent unauthorized data access, highlighting how a single overlooked security check can potentially expose sensitive user information.
