From a security standpoint, it is good practice to disable the Default Welcome page when installing Jet Hub. Having the Default Welcome page installed and available is an indication of a newly installed server. This can lead bad actors to believe the server could be running without awareness, and thus invite further probing. Insightsoftware recommends disabling the Default Welcome page as part of the Jet Hub installation/setup.
To disable the IIS Default Page in Internet Information Services
Launch Internet Information Services (IIS). See also the Microsoft documentation.
Locate the Jet Hub site in the list of sites in the left-hand pane and select it. Jet Hub Home opens in the center pane.
In Jet Hub Home, double-click Default Document. The Default Document section is displayed in the center pane.
In the right-hand pane, under Actions, click Disable.
Default Document has been disabled and your Jet Hub site is now more secure.
