Internet Information Services (IIS) 5 is a mature, high-performance Microsoft Windows 2000-based Web server, which builds on the success of IIS 4, the most popular Web server for Microsoft Windows NT 4. In this chapter, we'll examine some of the security features of IIS 5 as well as some of the server's new functionality.
Because IIS is a Windows 2000 system service and relies heavily on the security functionality in Windows 2000, it's assumed in this chapter that you have read Chapter 3, "Windows 2000 Security Overview," or have a good working knowledge of Windows 2000 security.
We'll cover the following topics in this chapter:
A New Feature of IIS 5—WebDAVDefined in RFC 2518 (http://www.ietf.org/rfc/rfc2518.txt), Web-based Distributed Authoring and Versioning (WebDAV) is a set of extensions to the HTTP 1.1 protocol that allows users to collaboratively edit and manage documents on Web servers. IIS 5, Microsoft Internet Explorer 5, and Microsoft Office 2000 support WebDAV.
You can find more information about WebDAV at the WebDAV Resources Web site (http://www.webdav.org) and at the Microsoft Developer Network (MSDN) Web site at http://msdn.microsoft.com/standards/WebDAV.asp.
