The frequency and strength of Distributed Denial of Service (DDoS) attacks are on the rise. Through the exploitation of millions of insecure Internet-of-Things (IoT) devices, the creation of botnets waging highly distributed volumetric attacks is easier and more impactful than ever before. In addition to larger attack volumes, efforts are shifting from the network and transport layers to the application layer (layer 7). Application layer attacks are far more sophisticated, often requiring fewer resources to bring down a website or application, and can disrupt operations with even greater impact.
DDoS attacks disrupt normal business operations by degrading website and application performance and availability, sometimes knocking them offline completely. The average hourly cost of downtime due to an infrastructure failure is $100,000 per hour. Attacks of this nature likely lead to customer churn, brand degradation, and lost business.
Websites and applications require the resilience and intelligence of a scalable network to combat the biggest and newest attacks. Protecting against threats should not degrade performance caused by security induced latencies and security services must be easy to configure to eliminate misconfigurations, which introduce new vulnerabilities.
