Configure Security Group

This setting gives us to setup a farewell rule to add a security layer for code files, databases, etc. It is possible to restrict traffic for a specified section of this solution. By adding new security groups we specify various Ports that we setup in the code to give defined access to a specific user.

Beyond certain specific ports like 3005, 3010, 3014, 3015, 3050, 4050, 3838, 6051, 27017, and 3306 we also keep HTTP, HTTPS, and SSH ports open for this instance.

Configure Security Groups - Ports

Quick Note:

-HTTP and HTTPS we keep open for players to allow requests from anywhere in the world.

-SSH to connect this EC2 instance from the local machine.

-Other mentioned ports have their own need which we used to increase the security to the next level.

-Make sure your protocols for each port should be defined as custom TCP.
