For the recent eWeek OpenHack 4 competition, Microsoft engineers built a Web site that withstood more than 82,500 attempted attacks. The site used SQL Server 2000 with the Microsoft .NET Framework, Microsoft Windows 2000 Advanced Server, and Internet Information Services (IIS) 5.0. Read how the engineers built and configured the solution, and learn about best practices that software developers and systems administrators can use to secure their own solutions at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetsec/html/openhack.asp .
