ASP.NET debugging enabled
Description
The ASP.NET application has debugging mode enabled in its configuration. Debug mode is intended for development environments only and should always be disabled before deploying to production. When enabled, debugging provides verbose error messages, extends request timeouts, and disables certain performance optimizations. This configuration is commonly left enabled inadvertently after troubleshooting production issues.
Remediation
Disable debug mode in the application's web.config file before deploying to production. Locate the <compilation> element within the <system.web> section and ensure the debug attribute is set to false:
<configuration>
<system.web>
<compilation debug="false" targetFramework="4.x" />
</system.web>
</configuration>After making this change, recompile and redeploy the application. For machine-wide enforcement, consider setting
<deployment retail="true" /> in the machine.config file, which overrides debug settings across all applications on the server. Verify the change by confirming that detailed error messages no longer appear to end users.
