Tcpdump is a commandline tool that is used to dump traffic on a network. This tool comes in hand when you want to analyse network captures within the command line. Basically it can do most of the wireshark job.
NOTE This guide might not be complete it just serve as a reference to me.
AWS API Gateway has the ability to pre-authenticate connections prior to launching the endpoint, by passing the authorizationToken to a Lambda function. There are clear benefits for simplifying end point security and also a reduction in duplicated code by utilising this feature. However I found the AWS examples were excessively complicated for what should be a very simple task.
So here's my example.
The main concern is that AWS Lambda authentication expects a very specific response and if that response is not given it will throw a 500 error with x-amzn-ErrorType: AuthorizerConfigurationException in the response header if the response object is not exactly as expected.
I personally use to handle the publishing part of my Lambdas, but I'll include an image of the API Gateway config.
