You can require users to provide a valid Microsoft® Windows®
user account name and password before they access any
information on your server. This identification process is
called authentication. Authentication can be set at the Web
or FTP site, directory, or file level. IIS provides
authentication methods to control access to your Web sites
and FTP sites.
Anonymous Authentication:-

Anonymous authentication gives users access to the public
areas of your Web or FTP site without prompting them for a
user name or password. By default, the IUSR_computername
account is used to allow anonymous access.

In IIS 6.0, anonymous authentication no longer requires the
Allow log on locally user right, because NETWORK_CLEARTEXT
is now the default logon type for anonymous and basic
authentication.

During setup, the IUSR_computername account is added to the
Guests group on the computer running IIS. Guests have the
same access as members of the Users group by default, except
for the Guest account, which is further restricted.

Basic Authentication:-

The Basic authentication method is a widely used,
industry-standard method for collecting user name and
password information. Basic authentication transmits user
names and passwords across the network in an unencrypted
form. You can use your Web server's encryption features, in
combination with Basic authentication, to secure user
account information transmitted across the network. To use
Basic authentication, grant each user the right to log on
locally. For easier administration, add each user to a group
that has access to the necessary files.

Digest Authentication:-

Digest authentication offers the same functionality as Basic
authentication; however, Digest authentication provides a
security improvement in the way that a user's credentials
are sent across the network. Digest authentication transmits
credentials across the network as an MD5 hash, or message
digest, where the original user name and password cannot be
deciphered from the hash. Digest authentication is available
to Web Distributed Authoring and Versioning (WebDAV)
directories. Digest authentication requires HTTP 1.1 compliance.

Advanced Digest Authentication:-

Under Advanced Digest authentication, user credentials are
stored on the domain controller as an MD5 hash. Because
credentials are stored in Active Directory as an MD5 hash,
user passwords cannot be feasibly discovered by anyone with
access to the domain controller, not even by the domain
administrator. Advanced Digest authentication is available
to Web Distributed Authoring and Versioning (WebDAV)
directories. In IIS 6.0, Advanced Digest authentication is
preferred over Digest authentication, but Digest
authentication is still available. Advanced Digest
authentication relies on the HTTP 1.1 protocol.

Advanced Digest authentication uses the UseDigestSSP
Metabase Property. This metabase key is a switch between
Digest and Advanced Digest Security Support Provider
Interface (SSPI) code. After the key has been set, the only
valid property values are 1 (true), 0 (false), or empty. If
the property is set to true, the new SSPI code for Advanced
Digest authentication is used. In all other cases (false,
empty, or not set), IIS uses the Digest authentication code.

Integrated Windows Authentication:-

Integrated Windows authentication (formerly called NTLM, and
also referred to as Windows NT Challenge/Response
authentication) is a secure form of authentication because
the user name and password are hashed before being sent
across the network. When you enable Integrated Windows
authentication, the user's browser proves its knowledge of
the password through a cryptographic exchange with your Web
server, involving hashing.
UNC Authentication:-

In IIS 6.0, you can use delegation of authentication, a
feature of IIS 6.0 and the Windows Server 2003 family, to
pass the authenticated credentials of the request user to a
remote file server on which a Universal Naming Convention
(UNC) share is located. Delegation of authentication, also
called UNC authentication, allows virtual directories mapped
to remote UNC shares to use local user authentication for
access to the shares. This is preferable to the alternative
of using a static user name and password, because you can
limit access to specific portions of the UNC share for each
user or group. Delegation of authentication works only with
authentication methods that can perform delegation, for
example, Basic authentication or Kerberos authentication.

IIS can be configured to secure a virtual directory as you
create it or to configure an existing directory.

.NET Passport Authentication:-

Microsoft® .NET Passport is a user-authentication service
and a component of the Microsoft .NET framework. The .NET
Passport single sign-in service and express purchase service
enable your business to deliver a fast, convenient, and
secure way for consumers to sign in and make transactions on
your site. With the .NET Passport single sign-in service,
you can map sign-in names to information in your databases,
which enables you to offer .NET Passport members a personal
Web experience through targeted ads, promotions, and
content. Using .NET Passport in this way potentially helps
you increase customer loyalty, sales, and advertising revenues.

.NET Passport uses standard Web technologies and techniques,
such as Secure Sockets Layer (SSL), HTTP redirects, cookies,
Microsoft JScript®, and strong symmetric key encryption to
deliver the single sign-in service. The .NET Passport
service is compatible with both Microsoft Internet Explorer
version 4.0 or later, and Netscape Navigator version 4.0 or
later. In addition, .NET Passport is compatible with some
versions of UNIX.

FTP Site Authentication:-

You can configure an FTP server to allow anonymous access to
FTP resources or to require Basic authentication in the form
of a user name and password corresponding to a valid Windows
user account.

Digest and Integrated Windows authentication cannot be used
with FTP sites. Available authentication settings must be
set at the site level for FTP sites.

HTTP Port number 80

Back Up the IIS Configuration:-
# In the IIS snap-in on the local computer, click the
Computer icon under Internet Information Services.
# Click Action and select Backup/Restore Configuration.
# Click Create backup, choose a name for your backup file,
and then click OK.NOTE: The default location of the backup
is the %SystemRoot%\system32\inetsrv\MetaBack folder. If you
want to save your backup file to another location, you can
copy the file from this default location to another
location. Keep a copy in the default location to allow for
an easy restoration. Note that by default, C:\Winnt is the
%SystemRoot% folder in Microsoft Windows 2000.
