572 Part IV: Securing Your Network, Host, and ApplicationTracing is configured using the element. Set enabled=“false” on productionservers as follows:If you do need to trace problems with live applications, it is preferable that yousimulate the problem in a test environment, or if necessary, enable tracing and setlocalOnly=“true” to prevent trace details from being returned to remote clients.Exception ManagementDo not allow exception details to propagate from your Web applications back to theclient. A malicious user could use system-level diagnostic information to learn aboutyour application and probe for weaknesses to exploit in future attacks.The element can be used to configure custom, generic errormessages that should be returned to the client in the event of an application exceptioncondition. The error page should include a suitably generic error message, optionallywith additional support details. You can also use this element to return different errorpages depending on the exception condition.Make sure that the mode attribute is set to “On” and that you have specified adefault redirect page as shown below:The defaultRedirect attribute allows you to use a custom error page for yourapplication, which for example might include support contact details.Note Do not use mode=“Off” because it causes detailed error pages that contain system-levelinformation to be returned to the client.If you want separate error pages for different types of error, use one or more elements as shown below. In this example, “404 (not found)” errors are redirected toone page, “500 (internal system errors)” are directed to another page, and all othererrors are directed to the page specified on the defaultRedirect attribute.
Chapter 19: Securing Your ASP.NET Application and Web Services 573RemotingDo not expose .NET Remoting endpoints on Internet-facing Web servers. To disableRemoting, disable requests for .rem and .soap extensions by mapping requests forthese file extensions to the HttpForbiddenHandler. Use the following elementsbeneath :. . .Note This does not prevent a Web application on the Web server from connecting to a downstreamobject by using the Remoting infrastructure. However, it prevents clients from being able to connectto objects on the Web server.Web ServicesConfigure Web services using the element. To establish a secure Webservices configuration:● Disable Web services if they are not required● Disable unused protocols● Disable the automatic generation of WSDLDisable Web Services if They Are Not RequiredIf you do not use Web services, disable them by mapping requests for the .asmx(Web service) file extension to HttpForbiddenHandler in Machine.config as follows:. . .
