Amazon_EC2_38

Instance with unencrypted Cassandra Client (TCP:9042) is potentially exposed to the public internet

Description

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

It is reccomended 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.
