Dns2TCP Service Detection

Info

Synopsis

The remote service supports the DNS-to-TCP protocol.

Description

The remote service supports the DNS-to-TCP protocol. This protocol hides network traffic protocols by embedding the traffic within seemingly innocuous DNS queries. This service can be used to bypass firewalls or proxies by obfuscating the true protocol within the DNS protocol.

Solution

Ensure that such services are allowed according to network policies and guidelines. Limit incoming traffic to this port if desired.
