The real cause of large DDoS - IP Spoofing

This post delves into the root cause of large-scale Distributed Denial of Service (DDoS) attacks, identifying IP spoofing as the primary enabler. It explains how IP spoofing works in both direct and amplification attacks, illustrating the technical challenges and internet design properties that make it possible. The post details how Cloudflare analyzes spoofed IP patterns and discusses solutions like BCP38 and the role of internet carriers in mitigating these threats, thereby expanding the understanding of network-level vulnerabilities within the security thread.
