The Domain Name System (DNS) is one of the core foundations of the internet. Every user and device in your network uses DNS to translate domain names to IP addresses, meaning it is impossible to run your business without it. Yet, DNS is often overlooked by organizations as a critical threat vector, making it an extremely tempting target for attackers. With the evolution of today’s DNS-layer threats, it is more important than ever for organizations to have a solution that can secure their DNS traffic and prevent the latest attacks using DNS.
While many organizations rightfully invest significant time and resources into protecting web and email attack vectors, many security professionals don’t realize the ease and prevalence of DNS abuse by attackers. In fact, many security teams don’t inspect DNS traffic for threats because they assume queries sent over DNS protocol and port 53 are benign. Other organizations don’t inspect DNS traffic because the sheer volume of that traffic is overwhelming, and looking for a sign of something malicious in that traffic is like looking for a needle in a haystack. This takes a great deal of time and resources—often too great an investment for organizations, especially those that assume DNS does not pose a significant threat.
