Understand the Problem:

The inability of external users to log in indicates potential issues with configuration or permissions.

Review Cognito Configuration:

Check for recent changes in Cognito user pool settings, such as password policies or authentication flow configurations.

Ensure the app client settings (e.g., callback URLs, OAuth flows) are correctly configured.

Review IAM Policies and Role Trust Relationships:

Verify that IAM roles used by Cognito (e.g., for identity providers) have the correct policies attached.

Ensure trust relationships for roles are properly configured to allow Cognito to assume them.

Advantages of Reviewing Configurations:

Addresses the root cause of login failures without disrupting user experience (e.g., resetting passwords).

Next Steps:

If no issues are found in the configuration, proceed with detailed logging and monitoring using CloudTrail (Option A).

The solution to receiving automated email notifications when AWS access keys are detected on code repository sites is to use Amazon EventBridge with Amazon GuardDuty findings. Specifically, creating an EventBridge rule that targets Amazon GuardDuty findings, particularly theUnauthorizedAccess:IAMUser/InstanceCredentialExfiltrationfinding type, allows for the detection of potential unauthorized use or exposure of AWS credentials. When such a finding is detected, EventBridge can then trigger an action to send a notification via Amazon Simple Notification Service (Amazon SNS). By configuring an SNS topic to send emails, stakeholders can be promptly informed of such security incidents. This approach leverages AWS's native security and monitoring services to provide timely alerts with minimal operational overhead, ensuring that the company can respond quickly to potential security breaches involving exposed AWS credentials.
