Do I need to apply the Microsoft Internet Information Server (IIS) 4.0 Security Checklist recommendations to IIS 5.0?
No; IIS 5.0 has its own checklist. You can find Microsoft’s “Secure Internet Information Services 5 Checklist” at http://www.microsoft.com/technet /prodtechnol/iis/tips/iis5chk.asp. This checklist is shorter than the IIS 4.0 checklist, mostly because Win2K improvements make many of the IIS 4.0 security recommendations obsolete.
