Executive Summary

This paper in progress paper discusses the development and evaluation of an open source secure web gateway. The proof of concept system uses a combination of open source software (including the Greasyspoon ICAP Server, Squid HTTP proxy, and Clam Antivirus) to perform the various security tasks that range from simple (such as passive content insertion) to more advanced (such as active content alteration) by modules installed on the server. After discussing the makeup of the proof of concept system the authors discuss their evaluation methodology for both effectiveness and performance.
