Web Portals, Gateway to Information or a Hole in our Perimeter Defenses - Deral Heiland
If web portals can be used to aggregate information and resources from multiple locations, and deliver it
to users at a single point of access. Could an attacker use these same functions and features to gain
access into unauthorized internal systems? In this presentation we will explore using a web portal
interface to query resources behind the firewall by tunneling request through the portal services using a
cross-site-scripting (XSS) like vulnerabilities.

Code Integration-Based Vulnerability Auditing
William B Kimball, Undergraduate Student, University of Dayton
There is a growing need to develop improved methods for discovering vulnerabilities in closed-source
software. The tools and techniques used to automate searching for these vulnerabilities are either
incomplete or non-existent. Fuzz-testing is a common technique used in the discovery process but does
not provide a complete analysis of all the vulnerabilities which may exist. Other techniques, such as API
hooking, are used to monitor insecure imported functions while leaving inlined functions still waiting to
be found. LEVI is a new vulnerability auditing tool (Windows NT Family) which addresses both of these
issues by using a code integration-based technique to monitor both imported and inlined functions.
Using this approach provides a more complete analysis of the vulnerabilities hidden within closed-
source software.
William Kimball is extremely passionate about computer security and is an undergraduate student at the
University of Dayton studying Computer Science. He recently received the Learn, Lead and Serve
Award for his research in Binary Vulnerability Auditing and participated in this years’ Ohio Academy of
Science. Kimball has also worked in security and networking for a Fortune 500 company.
