中等級 1人工審核alibaba

說明

Security groups provide stateful filtering of ingress/egress network traffic to Alibaba Cloud resources. It is recommended that all security group configured with fine grained rules. Configure fine grained security group rules is a very effective way of minimizing the impact of breach as resources outside of these rules are inaccessible to the ECS instance. Reported as a manual review item: the benchmark audit needs console review or organisational judgement.
