The process used to overcome the difficulties associated with processing all network traffic is based on processing summaries of network traffic rather than individual packets. The experimental approach described works by capturing individual packets from the network and summarizing the specific characteristics of the headers. These summaries can then be analyzed by using data mining tools that can identify abuse or unusual characteristics. The resulting analysis results can then be used to refine the summarization process to improve efficiency and to provide a means of responding to new threats. The authors explain that Internet abuse is a serious problem that undermines e-business commerce. Unfortunately, certain types of Internet misuse can only be identified and prevented within the network core. This is problematic because as Internet communication data rates rise, processing all network traffic in the hopes of ferreting out Internet abuse becomes increasingly difficult. The authors offer an overview of Internet misuse as well as discussions of Internet data rate issues, processing issues, legal issues, and practical issues. Figures, references
