Run the sample and extend the solution

Download the code base: Start by downloading the code base from the avp streamlit samples repository Set up your development environment: Install the AWS SDK for Python (boto3) and configure your AWS credentials. Install the AWS SDK for Python: pip install boto3 Log in to your AWS account: aws login --region $REGION Verify that your AWS Command Line Interface (AWS CLI), Python, and dependencies are correctly configured. . /verify-setup. sh Create your AWS resources: Use the AWS Management Console or infrastructure as code (IaC) tools to provision your Amazon Cognito user pool and Verified Permissions policy store.

. /deploy-demo-environment. sh Do you want to start the demo now? (Y/N): Y This provisions an Amazon Cognito user pool, a Verified Permissions policy store, and any sample resources needed for the demo. Verify the login screen: Figure 4: Verify login credentials Demo walkthrough and shut down: Interact with the demo and test the policies and features.

When you’re ready to exit, press Ctrl+C to shut down and stop. Define your Cedar policies: Start with basic policies and gradually add complexity as you understand the evaluation model. Implement authentication: Integrate Amazon Cognito authentication into your application with proper error handling. Add authorization checks: Implement authorization checks at critical access points in your application. For authentication, implement proper error handling for expired tokens, failed MFA challenges, and account lockouts.

Use the Amazon Cognito built-in token refresh flow. For authorization, place Verified Permissions checks at every API endpoint and UI component that accesses protected resources. Test thoroughly: Create test scenarios for each user role and permission combination.
