Abstract

DNS, Domain Name System, is one of the foundational protocols for Internet to work. It resolves hostnames to scientific disciplined addresses known as IP addresses which enables applications such as web browsers and humans to use internet or other networks easily. Because of its limited functionality, it is wide open in many enterprise firewalls with a very less attention from enterprise security monitoring. Due to all these factors, many tools have evolved to set up covert information tunneling channels through DNS which goes undetected causing significant information exfiltration risks to organizations and financial losses to ISPs. Hence, it's vital to investigate and prevent DNS tunneling. In this paper we walk through DNS overview, different DNS tunneling tools and techniques to block it.
