#securitygroup

Ensuring robust security is a paramount concern in cloud computing, and AWS offers powerful tools for managing and controlling access to resources. In this blog post, we will delve into a Python script designed to identify AWS security groups that permit all traffic within a specified region. By identifying and addressing such security configurations, you can bolster the overall security posture of your AWS infrastructure

This was frustrating, and maybe I missed it in the documentation, but I didn't see it anywhere - when you have two machines in the same AWS Security Group, the assumption would be that they can interchange network traffic freely between them (at least, that was my assumption), but they can't. If you want them to be able to talk to each other, you have to add the security group to itself as a valid connection endpoint.
