There are several authentication methods available to IIS administrators for controlling access to the server and files. These password authentication methods include Anonymous, Basic, Windows NT Challenge/Response, and digital certificates. In addition to these methods, you can add custom authentication methods by writing ISAPI filters.

Anonymous Access

When Allow Anonymous Access is enabled, users do not supply a username and password to access unprotected resources. Instead, IIS uses an individual guest account (typically lUSR_computername) as the login account and uses this account to open resources for the connected user.

The Internet Guest account IUSR_computername is created during IIS setup and is part of the Guests and Everyone groups. You should review the file permissions given to these groups to ensure they are appropriate for your anonymous users. You can explicitly deny the Internet Guest account access to sensitive information if it is not suitable for anonymous users.

Anonymous access authentication does not use passwords, thus preventing people from gaining access to sensitive information with fraudulent or illegally obtained passwords. For some situations, this can provide the best security.

Basic and Windows NT Challenge/Response Security

These two authentication methods require the user to provide a valid Windows NT username and password to the server before accessing resources.

TTP Basic Authentication

Basic authentication is the standard method as defined in the HTTP specification. Most browsers support it and will prompt the user for a name and password during the authentication process. The user account and password are sent unencrypted join the Web browser to the server.

Using Basic authentication means that you will send your Windows NT username and password unencrypted over public networks. Thus, intruders can easily learn usernames and passwords. Microsoft recommends using Basic authentication with SSL encryption or using the Windows NT Challenge/Response method of password authentication.

Windows NT Challenge/Response

Windows NT Challenge/Response is an authentication method created by Microsoft that does not transmit an actual password across the network. Instead, the server engages in a cryptographic exchange with the Web browser to prove the correctness of the supplied password. This method is significantly safer than HTTP basic authentication. Microsoft Internet Explorer versions 2.0 or later support Windows NT Challenge/Response authentication.

Note Windows NT Challenge/Response authentication takes precedence over Basic authentication. It means that if the user’s Web browser supports both methods, it will choose Windows NT Challenge/Response authentication.

Authentication with Certificates

Using the Web server’s SSL 3.0 security feature to authenticate users, the server checks the contents of an encrypted digital identification submitted by the user’s Web browser during the login process. Users obtain these digital identifications, called client certificates, from a mutually trusted third-party organization. Client certificates usually contain identifying information about the user and the organization that issued the certificate.

With the advent of the Internet, corporations can tap into the large potential customer base now connected online. The inherently open Internet has also raised security questions and spawned an array of safety requirements.

Authenticate Users

The need to identify and authenticate legitimate users (for example, subscribers) in order to provide them with access to information, content, and services while denying service to unauthorized users.

Resource Access Control

Security system with a fine-grained access control that will allow legitimate users access to resources, while protecting sensitive resources from hackers and unauthorized users.

Encrypted Communication

Ensure that corporations can set up private and tamperproof communications channels over the Internet for commerce and sensitive business-to-business transactions.

Auditing and Logging

Broad auditing and logging functionality to help track the site security, catch potential hackers, and deter attacks on the site.
There are four methods of security you can apply to your IIS computer. Users must pass these security checks before they are allowed to access a particular resource.

• IP Access – You can configure your Web server to prevent specific computers, groups of computers, or entire networks from accessing your Web server content. When a user initially tries to access your Web server content, the server checks the Internet Protocol (IP) address of the user’s computer against the server’s IP address restriction settings.IIS allows you to use DNS names in place of IP addresses, but there will be a significant performance reduction due to the name resolution.

• User Authentication – You can configure your Web server to allow anonymous (guest) access or to require a connecting client to provide a valid Windows NT logon in order to access any resources.

• Web Permission – You can configure your Web server’s access permissions—Read, Write, or Execute—for specific sites, directories, and files. These permissions will apply to all users regardless of their specific access rights. For example, you can disable the Read permissions for a particular Web site to prevent user access while you update the site’s content. When a user attempts to access the restricted Web site, they will receive an “access forbidden” error message.

• File Security – IIS relies on NTFS permissions for securing individual files and directories from unauthorized access. Unlike Web server permissions, which apply to all users, you can use NTFS permissions to precisely define which users can access your content and how those users are allowed to manipulate that content.

You can restrict the length of time articles are kept in a Microsoft NNTP Service newsgroup and also how much disk space a newsgroup can occupy by defining expiration policies for newsgroups. An expiration policy can apply to a single newsgroup or any number of newsgroups. You can set as many policies as you need. In each case, the oldest articles deleted first.

If you do not specify an expiration policy for a newsgroup, you should delete articles manually when they are no longer needed.

To create an expiration policy

1. Using Internet Service Manager, expand Default NNTP Site then click the Expiration Policies node.
2. From the Action menu, click New, and then click Expiration Policy.
3. Follow the instructions of the New Expiration Policy wizard.

You can modify an existing expiration policy, including changing the newsgroups to which the policy applies, using the General (Expiration Policy) property sheet.

To modify an expiration policy

1. Using Internet Service Manager, expand Default NNTP Site then click Expiration policies.
2. Select the expiration policy you want to modify.
3. From the Action menu, click Properties.
4. Change the options in the General (Expiration Policy) property sheet as needed.

Microsoft Internet Information Server (IIS) has multiple security options for keeping a server and its data safe from possible intruders and hackers.

IIS relies on the foundation of Microsoft Windows NT, a C2 certifiable system, for providing excellent protection.
Securing an IIS server is a combination of configuring Windows NT security and the individual IIS service’s security options.
If the server connected to the Internet, a router or firewall could be configured to provide additional security.

Steps to Secure IIS

The first step in securing IIS is to secure its foundation, Windows NT. Web, FTP, and other network services are only as secure as the platform on which they run.

Windows NT Server provides user account security and the NTFS file system to secure the server and its resources.
Before securing IIS services, you should configure your user accounts and groups, resource permissions, and security policies.

Securing User Accounts and Groups

Windows NT Security helps you protect your server and its resources by requiring assigned user accounts.
Every operation on a server running Windows NT identifies who is performing the operation. For example, the username and password you use to log on to Windows NT identifies you and defines what you can do on that server. You can control access to all computer resources by limiting the authority of these accounts.

Require Users to Choose Difficult Passwords

The easiest way for someone to gain unauthorized access to your system is with a stolen or easily guessed password.
To avoid unauthorized access to your system, require that all users—especially those with administrative rights— choose difficult-to-guess passwords (long, mixed case, alphanumeric passwords are best), and set the appropriate account policies. The User Manager utility allows you to set passwords.

Limit Administrator Accounts

Since accounts with Administrator-level authority have full access to your server, you should limit accounts with this authority by limiting members of the Administrators group. You can also rename the default Administrator account so hackers will not try to guess passwords for that account.

Applying Strict Account Policies

Configuring sound security policy is another must for a secure system. There are a variety of policy options to configure, such as password restrictions, rights on ‘ the system, and audited events.

For example, the User Manager utility provides a way for the system administrator to specify when account passwords expire.
It forces users to change passwords regularly. The administrator can also specify other policies, such as how many bad login attempts are tolerated before locking a user out.

Use these policies to manage your accounts, particularly those with administrative access, to thwart exhaustive or random password attacks.

Securing Resource Access

To secure resources, such as sensitive files and directories, NTFS must apply to the drives on which they exist. Using Windows NT Explorer with resources on an NTFS partition, you can specify what permission users and groups have to that resource. Remember, if there are conflicts between your NTFS settings and IIS settings, the most restrictive settings take effect.

Warning The file allocation table (FAT) file system does not provide file or directory security and should be avoided on secure systems.

Access to individual newsgroups, or sets of newsgroups, is controlled by setting Windows NT Server permissions for the directories that contain those newsgroups.

To restrict access to a newsgroup

1. Create Windows NT Server accounts for users.
2. Define Windows NT Server permissions for the directory that contains the newsgroup.
3. Set the authentication method used by Microsoft NNTP Service.

Authenticating Users

Microsoft NNTP Service supports two methods for authentication of users:

• Basic authentication
• Windows NT challenge/response authentication

To set the authentication method

1. Using Internet Service Manager, right-click Default NNTP Site, click Properties, and then select the Directory Security tab.
2. Under Password Authentication Method, click Edit.
3. Select the appropriate authentication method.

Limiting Access by IP Address

You can also limit access to all newsgroups by the IP address of the client computer. By default, all IP addresses can access Microsoft NNTP Service.

Either you can allow access to a specified list of IP addresses, or you can deny access to a specified list of IP addresses. You also can specify IP addresses using a domain name, but this adds the overhead of a DNS lookup for each connection.

To limit access by IP address

1. Using Internet Service Manager right-click Default NNTP Site, click Properties, select the Directory Security tab.
2. To grant access to all computers by default, choose Granted Access or choose Denied Access to deny access to all computers by default. In either case, you would then specify exceptions to the policy by listing IP addresses that will be denied (or allowed) access.
3. To add each IP address you want to allow or deny, click Add.
4. Click Single Computer. In the IP Address box, type the IP address of the computer. If you don’t know the IP address, click DNS Lookup.
5. Click Group of Computers. In the Network ID box, type the IP address. In the Subnet Mask box, type the subnet mask name for the group of computers.
6. Click Domain Name. In the Domain Name box, type the domain name of the computer.

If you want to control what articles posted to a newsgroup, you should use a moderated newsgroup. Articles submitted to a moderated newsgroup not published until the moderator for that newsgroup approves them.

When a user submits an article to a moderated newsgroup, Microsoft NNTP Service sends the article to the newsgroup moderator.
The moderator can either approve the article and send it back to Microsoft NNTP Service to be posted, or discard the article.

For discarded articles, the moderator can choose to send a message to the author of the article to explain why the article got rejected.

Establishing Moderated Newsgroups

To use moderated newsgroups, you must specify an SMTP e-mail server that is used to send articles to moderators or a directory where the articles stored for the moderators.

You can also specify a default moderator domain. If you choose to use the default moderator for a newsgroup, articles are sent to newsgroup_name @ defaul t_do main.

To enable moderated newsgroups

1. Using Internet Service Manager, right-click Default NNTP Site, click Properties, select the NNTP Settings tab.
2. In the SMTP server for moderated groups box, type either the Domain Name System (DNS) name or Internet Protocol (IP) address of the SMTP server, or type the path to the directory where articles stored for the moderators. The directory path must be a local directory or a network directory mapped to a drive letter.
3. In the Default moderator domain box, type the e-mail domain for default moderators.

To create a moderated newsgroup

1. Using Internet Service Manager, right-click Default NNTP Site, click Properties, and then select the Groups tab.
2. Select Create new newsgroup.
3. In the Newsgroup box, type the name of the newsgroup you want to create.
4. In the Description box, type a brief description of the newsgroup function.
5. Select either Moderated by default newsgroup moderator or Moderated
   by and then type the e-mail address of the moderator.

Microsoft NNTP Service uses six property sheets to configure different aspects of the service. All NNTP service property sheets can be accessed using the Internet Service Manager (ISM).

• News Site – Use this property sheets to set NNTP site identification and IP address, limit the number of connections allowed, to specify a connection timeout, and to enable or disable logging for an NNTP site.

• Security Accounts – Use this property sheet to control which users can access your server and to specify which account to use for anonymous client login requests.

• NNTP Settings – Use this property sheet to specify whether to allow clients to post messages, to limit message size or connection length, or to allow servers to pull messages from the server. You can also specify the Simple Mail Transfer Protocol (SMTP) server for moderated groups, set the default moderator domain and set the e-mail account for the site administrator.

• Home Directory – Use this property sheet to specify whether content should come from a directory located on this computer or a share located elsewhere, to set access restriction for the site, to set content control specifications, and to specify the Secure Communications method for the server.

• Directory Security – Use this property sheet to set the password authentication method for non-anonymous access, and to set TCP/IP access restrictions.

• Groups – Use this property sheet to create new newsgroups, to limit the number of resulting newsgroup matches, and to edit or delete newsgroups from a list of matching newsgroups.

Using the Editing and Deleting a Newsgroup property sheet, you can edit the properties of an existing Microsoft NNTP Service newsgroup or delete a newsgroup that you no longer need.

To edit or delete a newsgroup

1. Using Internet Service Manager, expand Default NNTP Site then click the Groups tab.
2. In the Matching newsgroups box, select a newsgroup. If you do not see the newsgroup you want, type the first few characters of the newsgroup name in the Newsgroup name box, and then click Find.
3. Click Edit to edit newsgroup properties, or click Delete to remove the newsgroup.

Microsoft NNTP Service installed as part of Internet Information Server (US) using the Custom setup option. System requirements for Microsoft NNTP Service are identical to those for the US.

Starting, Stopping, and Pausing NNTP Service

Microsoft NNTP Service runs as a service on Windows NT Server. The service is configured to start automatically. However, you can manually start, stop, and pause the service using Internet Service Manager, NNTP Service Manager (HTML), or the Services application under Windows NT Server Control Panel.

When you start Microsoft NNTP Service, it accepts new connections from users. When you stop Microsoft NNTP Service, it disconnects current users and does not accept new connections. When you pause Microsoft NNTP Service, it does not accept new connections but continues to service existing connections.

To start, stop, or pause Microsoft NNTP Service using Internet Service Manager

1. Start Internet Service Manager.
2. Select the Default NNTP Site entry.
3. From the Action menu, click Start, Stop, or Pause.

Creating a Newsgroup

Use the Groups property sheet in Microsoft NNTP Service to create a newsgroup. When you create a new newsgroup, Microsoft NNTP Service automatically creates the directory for the newsgroup.

To create a newsgroup

1. Using Internet Service Manager, right-click Default NNTP Site, click Properties, and then select the Groups tab.
2. Click Create new newsgroup.
3. In the Newsgroup box, type the name of the newsgroup you want to create.
4. In the Description box, type a brief description of the newsgroup function.
5. Click OK, then OK again to close the Default NNTP Site Properties dialog box.

Creating Virtual Directories Across Disk Drives

Virtual directories enable you to store newsgroup files on multiple disk drives. Using more than one disk drive can improve the performance of a heavily used drive. Using multiple disk drives can also provide more storage than using a single drive. Besides, virtual directories enable you to change the physical location of the directory without changing the name of the newsgroup.

Virtual directories contain part of the newsgroup hierarchy. For example, a virtual directory named Research could include all of the newsgroups named research*.

Virtual directories can be located on a local disk drive or a network drive. There is no advantage to creating a virtual directory on the same physical drive as the home directory.

You can create as many virtual directories as you need. You create virtual directories that match the structure of your newsgroup hierarchy.

To create a virtual directory

1. Using Internet Service Manager, expand Default NNTP Site, and select Directories.
2. From the Action menu, click New, and then click Virtual Directory.
3. Follow the instructions of the New Virtual Directory Wizard.

Microsoft NNTP Service implements the Network News Transport Protocol (NNTP), which is a client/server protocol. Microsoft NNTP Service is the server; Microsoft Internet Mail and News is a typical client.

Clients connect to Microsoft NNTP Service through a Transmission Control Protocol/Internet Protocol (TCP/IP) network. The default TCP port is 119 for regular connections. For encrypted SSL connections, the default TCP port is 563.

Microsoft NNTP Service runs as a service on Windows NT Server. The service is configured to start automatically. In Windows NT Server Control Panel under the Services application, the service name is “Microsoft NNTP Service.”

Posting Articles

You post newsgroup articles to Microsoft NNTP Service using a news client such as Microsoft Internet Mail and News. The client connects to Microsoft NNTP Service and requests to post the article to one or more newsgroups. Microsoft NNTP Service receives the connection request and verifies that the user is authorized to post to the specified newsgroups. Microsoft NNTP Service then adds the article to the newsgroup and updates the newsgroup index.

Viewing Articles

You view newsgroup articles on Microsoft NNTP Service using a news client such as Microsoft Internet Mail and NeWs. The first step in viewing newsgroup articles is to get a list of available newsgroups. The client connects to Microsoft NNTP Service and requests the list of available newsgroups. Microsoft NNTP Service receives the connection request, verifies that the user is authorized to access newsgroups, and then sends the client a list of all available newsgroups.

The second step is to select the newsgroup the user wants to view. The client requests the list of articles for the selected newsgroup. Microsoft NNTP Service verifies that the user is authorized to access the specified newsgroup and sends the client a list of all articles in that newsgroup.

As the user selects articles, the client requests the selected articles from Microsoft NNTP Service. Microsoft NNTP Service then returns the contents of the specified articles.

Microsoft NNTP Service Data Structures

Microsoft NNTP Service stores newsgroup articles in one or more directory hierarchies. Each newsgroup has its own directory, and each article is stored as a file in that directory.

The main directory is
C:Inetpubnntproot

by default, which can be changed on the Home Directory tab of the Microsoft NNTP Service property page. Yoir can create additional directory hierarchies on other disk drives or other computers by defining virtual directories.

The newsgroup directory has the same name as the newsgroup. Microsoft NNTP Service automatically creates the required directories when you create new newsgroups. For example, the newsgroup named entertainmenLnews is stored in the directory EntertainmentNews under the root directory

C:Inetpubnntprootentertainmentnews by default.

Newsgroup article files have a .nws extension. Microsoft NNTP Service also creates files that list the subjects of stored articles. Microsoft NNTP Service creates one of these subject files, which has a .xix extension, for every 128 articles in a newsgroup.

Newsgroup-type discussions

Microsoft NNTP Service is a fully functional newsgroup server that allows users in an organization to engage in newsgroup-type discussions with other users, both inside and outside the organization.

The NNTP Service provides support for creating local discussion groups for a single server using the industry-standard NNTP protocol.

This service allows users to read articles posted by others, post articles on their own, and join conversation threads about topics of interest.

Microsoft NNTP Service takes full advantage of standard Microsoft Windows NT Server administration tools for performance monitoring and event reporting.

When you install Microsoft NNTP Service, the Setup program installs a complete set of performance monitor counters. All Microsoft NNTP Service status and error messages written to event logs for viewing with Windows NT Event Viewer.

Microsoft NNTP Service manages access to newsgroups using Windows NT Server access control lists (ACLs). By setting the permissions for the directory that contains a newsgroup, you control who can access that newsgroup. You can also specify anonymous access to allow anyone to access a newsgroup.

Graphical administration tools

Microsoft NNTP Service offers you a choice of two graphical administration tools: Internet Service Manager and NNTP Service Manager (HTML).

You can perform all administration tasks with the tool that best meets your needs. Internet Service Manager uses Microsoft Management Console (MMC) to manage Microsoft NNTP Service from a computer on the same local area network (LAN). This tool can manage all IIS components using a single interface.

NNTP Service Manager (HTML) uses a Web browser, such as Microsoft Internet Explorer, to manage Microsoft NNTP Service from a computer on the same network or on the Internet. This tool only requires a Web browser on the administrator’s computer.

• Microsoft NNTP Service can also write to the IIS access log to record usage statistics and transactions.
• Microsoft NNTP Service supports the Network News Transport Protocol (NNTP) that is used for both client-to-server and server-to-server communication over the Internet. Microsoft NNTP Service supports popular NNTP extensions and is fully compatible with other NNTP clients and servers.
• Microsoft NNTP Service supports full-text and property indexing of newsgroup content using Microsoft Index Server, which included with IIS.

The optional Microsoft Content Replication System updates the access control lists for Microsoft NNTP Service automatically across multiple servers. It saves time and simplifies security administration.

Supports Content formats

In addition, Microsoft NNTP Service supports numerous content formats including:

• Multipurpose Internet Mail Extension (MIME)
• Hypertext Markup Language (HTML)
• Graphics Interchange Format (GIF)
• Joint Photographic Experts Group (JPEG)

Security options

Microsoft NNTP Service supports the following three security options for protecting your organization’s private information:

• Allow Anonymous : Allows anyone to access a newsgroup without providing a user name or a password.

• Basic Authentication : Requires users to provide a user name and a password, which are sent as clear text across the network.

• Windows NT Challenge/Response : Requires users to provide a user name and a password, which are encrypted for secure transmission across the network.

This protocol requires the Microsoft Internet Mail and News client.

To protect the information being sent across a public network, Microsoft NNTP Service supports Secure Socket Layer (SSL) channel encryption. SSL support includes certificate support to validate the identity of clients and servers.
