Consensus Roadmap for Defeating Distributed Denial of Service Attacks

The distributed denial of service attacks during the week of February 7 highlighted security weaknesses in hosts and software used in the Internet that put electronic commerce at risk. These attacks also illuminated several recent trends and served as a warning for the kinds of high-impact attacks that we may see in the near future. This document outlines key trends and other factors that have exacerbated these Internet security problems, summarizes near-term activities that can be taken to help reduce the threat, and suggests research and development directions that will be required to manage the emerging risks and keep them within more tolerable bounds. For the problems described, activities are listed for user organizations, Internet service providers, network manufacturers, and system software providers.
