Targeted Attacks

Targeted DDoS attacks are focused on taking down a specific site or application in a more traditional way by exploiting gaps that exist within the architecture or security of a legacy protocol, according to Jen Taylor, head of products at San Francisco-based Cloudflare.

Although legacy protocols around technologies such as ports are very broadly deployed, Taylor said they typically weren't built with the idea of defending against targeted attacks. Bad actors looking to carry out a targeted attack need to profile an application to understand who they're targeting and marshal resources effectively, according to Taylor.

Attackers often opt to take over and leverage capacity-related gaps that exist in areas like IoT devices to take over a specific site or application, Taylor said. Organizations can best defend themselves by getting onto a big network, locking down all nonessential ports, and profiling their applications before an attacker does, according to Taylor.
