Ensure the Default Network Security Group of Every Workspace Restricts All Traffic

높음레벨 1수동 검토ibmcloud

설명

It is recommended that the default security group for every workspace restricts all inbound (ingress) traffic, to enforce a least-privilege security posture and reduce unintended exposure of PowerVS resources. Starting with a default security group configuration that restricts all inbound (ingress) traffic reduces the chance of exposing PowerVS resources to unintended risks.
