Security and IAM Permissions

-IAM Permissions: - We should create an IAM policy if other AWS services access the API Gateway from the same account - We can leverage “Sig v4” capability where IAM credentials are in headers - Authentication = IAM | Authorization = IAM Policy - Resource policies: - Set policy on the API Gateway and set who can access it - Allows for cross account access (combined with IAM Security) - Allow for specific IP source
