I have an EC2 instance for running RServer. I've set up my security group, but AWS sent me a warning saying that my EC2 instance is accessible to anyone in the world.
This is my setup.
I have a VPC with IPv4 CIDR 10.0.0.0/16.
I have two subnets, each in a different availability zone. They are both associated with the VPC.
They both have these same rules. 
They are both connected with the same internet gateway, which is also attached to the VPC.
For route tables, they both have 10.0.0.0/16 with target local.
They also have a connection with another route table. Each of them connects with a different route table.
The first connects with route table A, which has two routes. It has 10.0.0.0/16 local active Propagated: No and 0.0.0.0/0 active Propagated: No. The second route is connected with the same internet gateway as the VPC.
The second subnet connects with route table B, which has the same routes as route table A.
I also have a security group. It is associated with the VPC. It has three inbound rules. The first one is type: SSH, Protocol: TCP, Port Range: 22 and source as my personal ip address followed by /32.
The second one is for RStudio Server and is type: Custom TCP Rule, Protocol: TCP, Port Range: 0.0.0.0/0 and the third one is also for RStudio Server and is type: Custom TCP Rule, Protocol: TCP, Port Range: ::/0.
I also have a network ACL which has default settings. It allows all inbound and outbound traffic.

I think you have typo for the RStudio IP range, which is 0.0.0.0/0, why don't restrict to limited IPs rather than global accessible? Even if it's TCP, you still need to limit the IP range
