Hackers can stop all eCommerce activity in its tracks when they target web servers and services, freezing revenue and causing huge disruption to the organization and its customers.

A SYN flood is a type of volumetric DDoS attack designed to make any online network or system inaccessible by flooding servers with TCP traffic which results in users being blocked from entering or using the network.

So how do you stop those servers being overwhelmed and keep them running in the event of an incident without disrupting the services in use? One way is to use a new stand-alone solution from G-Core Labs which distributes volumetric attacks across CDN servers to mitigate their impact.

Developed in partnership with chip maker Intel, G-Core Labs' XDP-based solution means you don't have to sacrifice a dedicated DDoS protection server for the job.

It adds a signature to every UDP packet from the end user to the server, so that packets with an invalid signature are routed to G-Core Labs' servers and only clean traffic forwarded to the protected server.

Last year, a 15 minute, 253Gbps DDoS attack using the UDP flood method was successfully repelled and Wargaming servers continued to deliver an uninterrupted service for the duration.
