Ensure no VPC security groups allow ingress from 0.0.0.0/0 to port 3389

中レベル 1手動レビューibmcloud

説明

VPC security groups provide stateful filtering of ingress/egress network traffic to Virtual Server Instances. It is recommended that no security group allows unrestricted ingress access to port 3389. Removing uncontrolled connectivity to remote console services, such as RDP, reduces a server's exposure to risk.
