Description

This course looks at the key Security services within AWS relevant to the Solution Architect associate exam. Core to security is Identity & Access Management, commonly referred to as IAM. This service manages identities and their permissions that are able to access your AWS resources and so understanding how this service works and what you can do with it will help you to maintain a secure AWS environment. IAM is an important service in ensuring your resources are secure.

Transcript

Now that we know a little bit more about User pools, let’s quickly examine how the authentication flow is handled by your application and the service.

Your user will be presented with a login screen or terminal of some sort from within your application. They will submit their credentials, either from having created an account directly or by logging into a third-party provider. 

The application will call the  InitiateAuth operation with those credentials. This API call kicks off the authentication flow. It directly indicates to amazon Cognito that you want to authenticate. 

If the call is successful - Cognito will respond either with a token or with a challenge.

A challenge can include CAPTCHAs or Dynamic challenge questions. These are normally used to help screen for bots. You can insert your own custom challenges if you wish. This will be sent back to the client and it now becomes Their problem.

When the client is ready to respond back to the server(cognito), they can reply with RespondToAuthChallenge and provide whatever information the challenge requires back. If the user fails the challenge, you can have Cognito set up to resend a new one. This can include multiple rounds until the user is successful or fails out.

If successful Cognito will shoot back some tokens for the client to use - Hurray authentication!
