Securing Lambda function URLs using Amazon Cognito, Amazon CloudFront and AWS WAF
Posted on December 31, 2022, Level intermediate Resource Length medium
Lambda function URLs is a dedicated HTTPs endpoint for a AWS Lambda function. You can configure a function URL to have two methods of authentication: IAM and NONE. IAM authentication means that you are restricting access to the function URL (and in-turn access to invoke the Lambda function) to certain AWS principals (such as roles or users). Authentication type of NONE means that the Lambda function URL has no authentication and is open for anyone to invoke the function. By Marcia Villalba.
