Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Microsoft's strategy to defend against network-based distributed denial-of-service DDoS attacks is unique due to a large global footprint, allowing Microsoft to utilize strategies and techniques that are unavailable to most other organizations. Additionally, Microsoft contributes to and draws from collective knowledge aggregated by an extensive threat intelligence network, which includes Microsoft partners and the broader internet security community. This intelligence, along with information gathered from online services and Microsoft's global customer base, continuously improves Microsoft's DDoS defense system that protects all of Microsoft online services' assets. The cornerstone of Microsoft's DDoS strategy is global presence. Microsoft engages with Internet providers, peering providers public and private , and private corporations all over the world. This engagement gives Microsoft a significant Internet presence and enables Microsoft to absorb attacks across a large surface area. As Microsoft's edge capacity has grown over time, the significance of attacks against individual edges has substantially diminished. Because of this decrease, Microsoft has separated the detection and mitigation components of its DDoS prevention system.
