You are hosting an application configured to stream media to its clients on TCP ports 3380-3384, 3386-3388, and 3390. The Inbound tab below shows three incoming security group policies attached to this instance. Which policy should you use?

Question

Accepted Answer

The rule that exposes TCP ports 3380-3390 would also publicly expose port 3389 (RDP) to the entire internet. Write separate rules to only expose the needed ports.

Answer

The first security group rule allows all traffic into this instance. Exposing your entire instance to the whole internet leaves the server open to various attacks of the other services running on different port numbers.

Answer

Verify that the AWS account owners actually control the entire CIDR C block for 12.228.11.0-255 and these are secured IPs for RDP access into this instance.

Answer

There are no recommendations to make.
