Description
RDS security groups should permit access only to necessary ports to prevent access to potentially vulnerable services on other ports.
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" "ingress-rds-test-group" {
name = "ingress-rds-test-group"
description = "Ingress rds"
ingress {
from_port = 3306
to_port = 3306
protocol = "tcp"
cidr_blocks = ["192.168.1.0/24"]
}
}
