An organization's DNS systems can be a gateway for intruders looking to exfiltrate sensitive data without setting off alarms. Knowing what's at stake and how to protect against DNS tunneling can thwart attacks before they start.
Domain name system (DNS) tunneling is a pervasive threat that enables hackers to get any data in and out of a company's internal network while bypassing most firewalls. The domain name system translates numeric internet protocol addresses that browsers can then use to load web pages - threat actors use tunneling to exploit this process and steal data by hiding it inside DNS traffic.
