This step-by-step article describes how to configure the URLScan security tool to protect ASP.NET Web applications.
URLScan is an Internet Server API (ISAPI) filter that screens and monitors HTTP requests for Internet Information Server 4.0, Internet Information Services 5.0, and Internet Information Services 5.1 (IIS). URLScan is used to reduce the exposure of IIS to potential Internet attacks.
By default, URLScan does not make special accommodations for file name extensions that ASP.NET Web applications use. You can change the URLScan configuration to add an extra layer of security for these applications. You must disable or enable different file name extensions for application level tracing, XML Web services, and remoting.
