Introduction To Iis 7

  1. 1. What’s new and Features in IIS 7 Windows Server 2008 featuring Internet Information Services 7.0 (IIS7) is a powerful Web application and services platform that delivers rich Web-based experiences. It offers improved administration and diagnostic tools to help achieve lower infrastructure costs on a variety of popular development platforms. With improved reliability and scalability, IT professionals and developers can manage the most demanding Web serving environments, from a single Web server to a large Web farm. IIS7 is a major upgrade of IIS, and will ship in both Windows Vista as well as Windows 2008 Server. It includes a ton of new functionality, including some very rich integration with ASP.NET. The main features of IIS 7 is as follows 1. IIS7 is faster and more efficient than any other earlier version of IIS. 2. With IIS7 you can manage whole Web farms from one place 3. IIS7 allows you to delegate management workload with site owners. Site owners can also remotely manage their sites and applications over HTTPS from Windows Vista, Windows XP, Windows Server 2003, and Windows Server 2008. IIS7's XCopy deployment model even allows you to deploy applications preconfigured! 4. IIS7 is much more flexible and customizable than before, allowing you to fine tune the server (including server core!) to minimize security footprint and downtime due to patching. 5. You can save loads of time by automating more tasks with the interface that is right for you. 6. If you do run into issues, IIS7 makes it easy to resolve site issues faster, minimizing down time due to that bone headed developer on your staff. 7. IIS7 includes built-in support for PHP, making it the best Web server for both Open Source languages and .NET. Why would you want to deploy, manage, patch and troubleshoot that Linux+Apache server to support those PHP apps, when you can just use Windows!? 8. IIS7 makes it easy to publish content securely over FTP/SSL or Web DAV! 9. Windows and IIS7 are cheaper than ever with the new Windows Web 2008 product. This version of Windows is super inexpensive and supports all the great features of IIS, SharePoint, SQL, Windows Media server and more for Internet facing sites! 10. And as if that isn't enough, IIS7 is getting better every day with new IIS7 Extensions like built-in progressive streaming and playlist support for media content, URL Rewrite capabilities, integrated database management, powershell support, and much much more.
  2. 2. 11. The ability to now have HttpModules and HttpHandlers participate in all requests to a server. You no longer need to map requests to the ASP.NET ISAPI in order to write managed modules that participate in requests. This makes building modules for flexible authentication, authorization, logging, url-rewriting, auditing, etc. super easy with .NET. You could even now have an ASP.NET HttpModule provide forms-authentication to a PHP or JSP page (in addition to .htm files and static files like images and movies). 12. Integration of the ASP.NET configuration system with IIS. IIS now uses the same web.config configuration model as ASP.NET, which means you can have both ASP.NET and IIS configuration settings in the same file together. You can now set things like default pages, IIS security, logging, etc within a web.config file and xcopy/ftp it to a server. This should simplify deployment and installation of applications considerably. It also enables quot;delegated administrationquot; for hosting scenarios -- where a hoster provides the application developer the ability to configure certain settings in their web.config file without requiring full admin privledges. 13. An integrated Admin UI tool that manages both IIS and ASP.NET settings together. Included within this rich GUI is support for things like the Membership, Roles and Profile providers (so you can create/delete users directly within the GUI tool -- regardless of what provider is configured). The admin tool also supports remote delegated admin over http -- which means you can point the rich-client admin tool at a shared hoster server and manage your users/roles/ profile settings remotely over http (which is pretty cool). 14. Much better request auditing and error debugging. We have a new feature we call quot;Failed Request Event Bufferingquot; (affectionately known as quot;FREBquot;), which allows administrators to configure applications to automatically save request information anytime an error occurs during a request, or if a request takes longer than a specified amount of time to complete (note: if the request completes ok this information can then be just thrown away -- and so doesn't fill up your disk log). This allows you to easily go in after the fact and see what exactly happened during a request that failed, as well as analyze any error exceptions. This can even capture tracing messages generated within ASP.NET or within any component or class library that uses System.Diagnostics -- which makes it much easier for developers and admins to instrument and analyze what is going on with systems at runtimes. 15. Much better configuration APIs and command-line tools. In addition to new config and admin APIs (including a nifty one that you can use to get a listing of all quot;activequot; requests being processed by the server -- as well as what state they are in), we now have a great command-line admin story that you can use to set/modify/retrieve all configuration information as well as manage the server (start/stop individual apps, lookup their health state, register new apps, refresh SSL certs, etc). The command-line tool and APIs are also extensible, so you can plug in your own providers and extensions to them. 16. In IIS 7.0 we have unified IIS and ASP.NET two models to produce a new robust pipeline that does the best that both older models did. IIS still supports all the old authentication protocols but also now supports forms authentication which can protect against all content types and does not rely on Windows accounts. In addition to supporting all the old features you have
  3. 3. come to know and love we have also enhanced some of them such as the anonymous authentication feature. 17. In IIS 7.0, you have two authorization solutions. The first is to use the ASP.NET authorization model. This method requires defining all your authorization rules in the <system.web> configuration and requires zero changes for applications that already have rules written for ASP.NET. The second model is to move to the new IIS 7.0 authorization architecture. This model is very similar to ASP.NET's model with some minor changes: 18. Forms authentication has been part of ASP.NET and allows both Windows and non Windows identities to authenticate themselves and get a user object that applications can later use. IIS 7 now fully supports forms authentication and can be configured to protect access to all content types. 19. In IIS 7.0Web service Extension restriction list feature has been slightly modified so that its name now reads quot;isapiCgiRestrictionListquot; -- but otherwise it acts and behalves as it had in IIS 6.0. The reason for this change was to stress its true usage. In IIS 6.0 this feature was added to ensure rogue ISAPI or CGI binaries could not copied to your IIS servers and then be allowed to execute 20. IP Restrictions works in the exact same manner as it had in the past except we now support a new property called quot;allowUnlistedquot;. This property was added to make it easier to configure security policies for your system at a global level. For example, if your policy required only certain IP addresses to be allowed but to reject all others that are not listed was not very easy to do in the past. Similarly, rejecting only a given set of IP addresses and allow ing all that are not listed can easily be done now. As a server administrator you can set a global policy and then lock this value so it cannot be changed on your server by application or site administrators Disadvantages 1. Passport authentication is no longer supported in the Windows Server 2008 operating system. Customers using passport should consider moving to its replacement Active Directory Federation Services (ADFS). 2. In IIS 6.0, Microsoft introduced a new authorization model based on AZMan rules. In IIS 7.0 Microsoft have depreciated this feature in favor of a new model that is very similar to the ASP.NET authorization model How IIS 7.0 Determines the Authenticated Identity In IIS 7.0 the authentication rules are processed by the core engine in a similar manner as they were in previous versions of IIS with only some minor changes. To better understand the processing order, here are the rules based on the order IIS evaluates them:
  4. 4. 1. First, IIS determines if a username and password has been configured at the virtual directory. If a set of credentials have been defined, those credentials will be used. For pre-IIS 7.0 administrators, these credentials are the UNC credentials 2. If no credentials are configured at the virtual directory then IIS will use the credentials provided during authentication. These credentials can belong to the identity that is configured for anonymous authentication or the credentials provided by the user during the authentication handshake when Basic, Digest, or Windows authentication is enabled 3. If no authenticated user was established (for example, forms authentication is enabled) it will determine if the process identity should be used 4. If we do not have an identity at this point, IIS will return an access denied SSL In IIS 6.0, IIS had stored SSL related information in the metabase and had managed a large part of the SSL negotiation process in conjunction with HTTP.SYS. In IIS 7.0, we have moved most of this configuration into HTTP.SYS's store. To illustrate how each of the IIS 6.0 configuration settings are carried over into IIS 7.0's configuration (or HTTP.SYS configuration), the following chart has been constructed below. IIS 6.0 Metabase Description of property IIS 7.0 Architecture configuration AccessSSLFlags is bitmask of AccessSSL AccessSSL128 AccessSSLNegotiateCert Property still supported in IIS 7.0 AccessSSLFlags AccessSSLRequireCert configuration in the <access> section AccessSSLMapCert 0 value means no SSL. This value will now be stored in http.sys in Enable or disable CRL (certificate revocation list) CertCheckMode the PHTTP_SERVICE_CONFIG_SSL_PARAM checking. object. RevocationFreshnessTime If the RevocationFreshnessTime property is set to 1 This value will now be stored in http.sys in (true), then the certificate revocation list (CRL) on the the PHTTP_SERVICE_CONFIG_SSL_PARAM certificate client is updated by the CRL from the object.
  5. 5. remote location, even if the CRL that is cached on the certificate client is valid. The default timeout interval is one day unless you use the RevocationURLRetrievalTimeout to specify a different timeout interval (in minutes). This property is still supported in IIS 7.0 The SecureBindings property specifies a string that is configuration under the <binding> section for SecureBindings used by IIS to determine which secure network <sites>. The protocol used needs to by endpoints are used by the server instance. quot;httpsquot;. The SSLAlwaysNegoClientCert property controls SSL client connection negotiations. If this property is set to true, any time SSL connections are negotiated, the server will immediately negotiate a client certificate, This value will now be stored in http.sys in SSLAlwaysNegoClientCert preventing an expensive renegotiation. Setting the PHTTP_SERVICE_CONFIG_SSL_PARAM SSLAlwaysNegoClientCert also helps eliminate client object. certificate renegotiation deadlocks, which may occur when a client is blocked on sending a large request body when a renegotiation request is received. This value will now be stored in http.sys in The SSLCertHash property is used to store the hash of SSLCertHash the PHTTP_SERVICE_CONFIG_SSL_PARAM the SSL certificate being used. object. The SslCtlIdentifier property contains a unique value This value will now be stored in http.sys in that identifies a specific certificate trust list (CTL). It SslCtlIdentifier the PHTTP_SERVICE_CONFIG_SSL_PARAM must be used with SslCtlStoreName to accurately object. reference a CTL. The SslCtlStoreName property contains the name of This value will now be stored in http.sys in the CryptoAPI store that contains certificate trust lists SslCtlStoreName the PHTTP_SERVICE_CONFIG_SSL_PARAM (CTL). It must be used with SslCtlIdentifier to object. accurately reference a CTL. The SSLStoreName property is used to store the name This value will now be stored in http.sys in SSLStoreName of the store where the key pair of the certificate the PHTTP_SERVICE_CONFIG_SSL_PARAM resides. object. The SslUseDsMapper property specifies whether IIS is This value will now be stored in http.sys in to use the Windows Directory Service certificate SslUseDsMapper the PHTTP_SERVICE_CONFIG_SSL_PARAM mapper or IIS certificate mapper. If SSLUseDSMapper object. is set to false, IIS uses the IIS certificate mapper. Compatibility of IIS 7 with OS
  6. 6. Microsoft considers IIS 7 is a part of the operating system (Win2K8 or Vista), so it's tied to the version of Windows you're using. You need to use either Windows Vista or Windows 2008 to have IIS7.
