GigaOM Radar for Domain Name System (DNS) Security

The domain name system (DNS) is fundamental to every modern organization. It’s the backbone of communications and the means by which clients connect with services both internally and externally. It is a service so fundamental to the basic day-to-day operations of every network that it must be both ultra-secure and resilient. However, the reality is that it is not. In fact, the DNS is vulnerable. Attacks of all types that can undermine the DNS, such as cache poisoning, DNS hijacking, amplification, spoofing, and tunneling, continue to increase.

The impact of a DNS cyberattack on an enterprise can be devastating. It can result in the loss of sensitive data, deployment of malicious code, and denial of access to key services, all of which can result in significant financial losses and reputational damage. Protecting DNS should be a priority, and that means using a solution with a range of security capabilities. A good DNS security solution has a unique value in the overall security chain. This stems from its operation early in the communications process. The vast majority of malicious activity in an infrastructure will make a DNS call; by securing and identifying malicious calls at inception, proactive security can be implemented from the beginning of an attack, helping secure an organization more effectively.
