![]() ![]() No analogy is perfect, however, and there are a few more wrinkles to the DNS amplification story, so let’s look more closely at the details of this attack. ![]() ![]() So, while most DDoS attacks work by overwhelming a system with a huge quantity of average-sized packets, a DNS amplification attack uses larger packets to achieve the same result. The flow of traffic is completely impaired-not by a sudden onslaught of thousands of cars but by several vehicles so large that normal traffic can’t flow through. ![]() Instead of thousands of cars flooding the freeway at one time, imagine six wide-load trucks traveling side by side along that same six-lane freeway. Thousands of cars crowding the freeway all at once completely impair the normal flow of traffic.Ī DNS amplification attack uses different techniques to accomplish the same end goal of denying service. Think of it like bumper-to-bumper, stand-still traffic on a six-lane freeway near a stadium when a concert or sporting event ends. 1 Most DDoS attacks are volumetric in that they bombard a victim’s network with more traffic than it can handle. As with all DDoS attacks, the goal of attackers is to keep users from accessing a networked system, service, website, application, or other resource by making it slow to respond or disabling it entirely. What Is a DNS Amplification Attack?Ī Domain Name System (DNS) amplification attack is just one of many types of distributed denial-of-service (DDoS) attacks.
