It is recommended to remove the rules that allow permissive SSH/Remote/Admin access.
If public interface exists, remove it and limit the access scope within the VPC only to applications or instances that requires access.
As a further protection, use CloudGuard Dynamic Access Leasing to limit access to SSH/Remote Desktop only from allowed sources and only when needed.
