Ensure no VPC security groups allow ingress from 0.0.0.0/0 to port 22

中级别 1人工审核ibmcloud

说明

VPC security groups provide stateful filtering of ingress/egress network traffic to Virtual Servers. It is recommended that no security group allows unrestricted ingress access to port 22. Removing uncontrolled connectivity to remote console services, such as SSH, reduces a server's exposure to risk.
