Disseminating Security Updates at Internet Scale

Disseminating Security Updates at Internet Scale describes a new system, &quote;Revere&quote;, that addresses these problems. &quote;Revere&quote; builds large-scale, self-organizing and resilient overlay networks on top of the Internet to push security updates from dissemination centers to individual nodes. &quote;Revere&quote; also sets up repository servers for individual nodes to pull missed security updates. This book further discusses how to protect this push-and-pull dissemination procedure and how to secure &quote;Revere&quote; overlay networks, considering possible attacks and countermeasures. Disseminating Security Updates at Internet Scale presents experimental measurements of a prototype implementation of &quote;Revere&quote; gathered using a large-scale oriented approach. These measurements suggest that &quote;Revere&quote; can deliver security updates at the required scale, speed and resiliency for a reasonable cost.Disseminating Security Updates at Internet Scale will be helpful to those trying to design peer systems at large scale when security is a concern, since many of the issues faced by these designs are also faced by &quote;Revere&quote;. The &quote;Revere&quote; solutions may not always be appropriate for other peer systems with very different goals, but the analysis of the problems and possible solutions discussed here will be helpful in designing a customized approach for such systems.
