Instance with service 'SQL Server Analysis Services' (TCP:2383) is exposed to a small network scope

Services and databases store data that may be sensitive, protected by law, subject to regulatory requirements or compliance standards. It is highly recommended that access to data will be restricted to encrypted protocols. This rule detects network settings that may expose data via unencrypted protocol over the public internet or to a too wide local scope.

REMEDIATION

Limit the access scope for Instance with service 'SQL Server Analysis Services to only allow access in internal networks and limited scope.

If public interface exists, remove it and limit the access scope within the VPC only to applications or instances that requires access.
