I don’t understand how to securing the API gateway. In this project, I haven’t found the materials about that. So, If you able to give me info, please give me resources for new knowledge.
Hi, great question!
There are various ways to secure APIs. One is with aws_iam authorizer in every service. Another one is in the handler function, in the accept allow origin header, put the IPV4 of the source you want to accept requests from.
