Ensure that SSH access is restricted from the internet

AltaNível 2Revisão manualalibaba

Descrição

Security groups provide stateful filtering of ingress/egress network traffic to Alibaba Cloud resources. It is recommended that no security group allows unrestricted ingress access to port 22 or port 3389. Removing unfettered connectivity to remote console services, such as SSH or RDP, reduces a server's exposure to risk. Reported as a manual review item: the benchmark audit needs console review or organisational judgement.
