Description
Removing unfettered connectivity to remote console services reduces a server's exposure to risk.
How to fix?
Set the ingress.cidr_blocks attribute with a more restrictive CIDR block, for example 192.168.1.0/24.
Example Configuration
resource "aws_security_group" "allow_some_cidr_valid" {
name = "allow_some_cidr_valid"
description = "Allow from valid CIDR"
ingress {
from_port = 23
to_port = 23
protocol = "tcp"
cidr_blocks = ["192.168.1.0/24"]
}
}
