Dev2Prod Demo -Achieve Compliance-Ready Access Control with AWS Cognito & Azure Entra ID Federation

Managing user access across microservices is complex — especially under frameworks like ISO 27001, SOC 2, or HIPAA.In this post, we’ll show how AWS Cognito can simplify secure login and access control for a real DevSecOps solution with an React frontend and Python FastAPI backend.

🔐 The Challenge

Modern apps often have multiple services, APIs, and environments. Without unified identity management, access becomes inconsistent — a compliance and security nightmare.

⚙️ Our Solution: AWS Cognito Access Flow

Below is a screenshot of our Cognito login integration in action:

After a secure OIDC login with PKCE, users receive scoped tokens (Access & ID) used across the microservices environment. The backend validates each token using Cognito’s JWKS public keys — ensuring zero trust and least privilege at every call.

🧩 Why It Matters

• Unified Authentication across frontend and backend microservices.

• Dynamic Access Rights – users are automatically mapped to roles and permissions.

• No Static Credentials – compliance-friendly by design.

• Seamless Integration – works with EKS, Vault, and ArgoCD pipelines.

🛡️ Compliance Alignment

Framework	Control Reference	What’s Covered
ISO 27001	A.9 – Access Control	Federated identity, least privilege
SOC 2	CC6.1 – Logical Access	Token-based access enforcement
HIPAA	§164.312(a)	Unique user identification

Each login, access, and role mapping is fully auditable and logged for compliance evidence.

📊 Engineering Highlights

• OAuth2 + OpenID Connect with PKCE

• JWT validation in FastAPI microservices

• Secure session management and token refresh

• Integration with CI/CD and audit-ready configurations

✅ Summary

Access control doesn’t need to slow innovation.With AWS Cognito, you get secure authentication, compliance coverage, and scalable identity management — all in one flow.
