Windows NT Challenge/Response (also called
NTLM) is a more secure authentication method than Basic Authentication. In
Windows NT Challenge/Response, the Web browser or FrontPage client first
attempts to use the Windows NT credentials used to log on to the computer
on which the browser or FrontPage client is running. If those credentials
are rejected Windows NT Challenge/Response will prompt the user for a name
and password. The username and password are securely encrypted in a
multiple transaction interaction between the client and Web server. This
interaction is secure against network snoopers that attempt to break into
systems by monitoring network traffic between a client and a
server. |
