Howto Disable the Server Header in IIS

Steven Erat just pointed me to a technote ( from Macromedia Adobe called: Configuring ColdFusion MX 7 Server Security in the comments of my securing apache config article. In the technote I found that you can disable the Server header on IIS by setting the HKLM\SYSTEM\CurrentControlSet\Services\HTTP\Parameters\DisableServerHeader registry entry to 1.

Why is this a good idea? It makes you less of a target for attackers who scan IP ranges for particular servers. It won't actually make your server any more secure.

While you are securing your server, make sure you disable SSLv2 and other weak protocols and ciphers on IIS.

I should point out that this method only works on IIS6+ Windows 2003 I believe.

ServerMask for IIS takes this concept a bit further for full IIS security masking:
