User:Bill Sempf

In 1992, Bill Sempf was working as a systems administrator for The Ohio·State University under Sandy Wambold, and formalized his career-long association with internetworking. While working for one of the first ISPs in Columbus in 1995, he built the second major web-based shopping center, Americash Mall, using Cold Fusion and Oracle. Bill's focus started to turn to security around the turn of the century. Internet-driven viruses were becoming the norm by this time, and applications were susceptible to attack like never before. In 2003, Bill wrote the Security and Deployment chapters of the often-referenced Professional ASP.NET Web Services for Wrox, and began his career in pen testing and threat modeling with a web services analysis for the Ohio Department of Health. Currently, Bill is working as a security-minded software architect specializing in the Microsoft space. He has recently designed a global architecture for a telecommunications web portal, modeled threats for a global travel provider, and provided identity policy and governance for the State of Ohio. Additionally, he is actively publishing, his latest being the C# 2010 All In One. Bill is an organizer for the Columbus chapter of OWASP.
