How Do I Prevent Cluster Nodes from Being Exposed to Public Networks?

If access to port 22 of a cluster node is not required, you can define a security group rule that disables access to port 22.
Do not bind an EIP to a cluster node unless necessary.

If remote login to a cluster node is required, you are advised to use Cloud Bastion Host (CBH) as the transit node to connect to the cluster node.
