Cloudflare’s Approach to Managing Distributed Denial of Service (DDoS) Attacks
Executive Summary
DDoS attacks on the internet have become increasingly frequent and sophisticated. At Cloudflare, we have developed a robust and innovative approach to actively manage these attacks to protect our customers. By leveraging our global network of data centers and implementing cutting-edge threat intelligence and mitigation techniques, we ensure the availability, performance, and security of online services we support.
Introduction
Distributed Denial of Service (DDoS) attacks are a significant threat to businesses and organizations around the globe. These attacks aim to overwhelm a targeted server, website, or online service with an immense volume of traffic, often originating from multiple sources to disrupt or completely hinder the service’s availability. They can cause significant financial losses, reputational damage, and service disruptions, impacting end-users’ experience and overall business operations.
