Abstract

Thanks to broadband Internet access, more people are using the computer network to do their everyday activities than ever. However, insufficient security measures from the service providers leave most Internet users defenseless against malicious attacks through web pages, e-mails, and other application-specific network transfers. As a result, it has been estimated that computer network intrusions cost global businesses over $55 B in damages in the year 2003 alone. Currently, one of the most effective ways to detect and filter such network attack is deep packet inspection. While there are a few systems using deep packet inspection techniques, most are software system running on processors that lack the resources to keep up with fast networks such as gigabit Ethernet. The most essential, yet computationally intensive task of deep packet inspection is dynamic pattern search. Therefore, my research has focused …
