Introducing IIS7: Microsoft’s Next Generation Web Server

1. Introducing IIS7:Microsoft’s Next Generation Web Server Eric Nelson Application Architect http://blogs.msdn.com/ericnel “ISV Stuff”

2. Proven Scale MySpace - 23 Billion Page* Views/Month Microsoft.com - 10k Req/sec & 300K Connections Match.com 30 million page view daily Proven Trust 54% of Fortune 1000 use IIS (port80software.com) Proven Security No critical IIS 6 hotfixes since RTM as of 5/20/07 A solid foundation to build on IIS 6 Today : A Proven Platform

3. IIS 7 – Microsoft.com • Beta 3 of Windows Server 2008 on June 12 • Great Compatibility • 99%+ ASP and ASP.NET worked • One application encountered breaking change out of 260 • Classic ASP mode and AppCmd • And loved • New UI, death of metabase, shared config, failed request tracing etc. • http://blogs.technet.com/mscom/archive/2007/09/07/the-tasty-morsels-found-in-dogfood-mscom-ops-top-10-changes-in-iis7-0.aspx

4. Internet Information Services (IIS) 7.0 CreateStreamlined Servers Modular Architecture Reduced Attack Surface Extensible Design Extend/Modify IIS Features Integrated with .NET Rapid Application Deployment Manageable Built in Request Tracing More than a Web server, Internet Information Services 7.0 provides an accessible, extensible platform for developing and reliably hosting Web applications and services IIS 7.0 Enhancements FastDiagnostics

5. Modular and Extensible Design

6. The Many Benefits of IIS7’s Modular Design

7. IIS6 Architecture - Request Processing Monolithic implementationInstall all or nothing… Authentication NTLM Basic Anon … Determine Handler CGI Static File ASP.NET ISAPI PHP … Send Response Extend server functionality only through ISAPI… Log Compress

8. IIS7 Architecture - Request Processing Server functionality is split into ~ 40 modules... Authentication Authentication NTLM Basic Anon Authorization … Modules plug into a generic request pipeline… ResolveCache Determine Handler CGI … Static File ExecuteHandler Modules extend serverfunctionalitythrough a public module API. ISAPI … … UpdateCache Send Response SendResponse Log Compress

9. The New IIS 7 Manager • Completely redesigned IIS Manager • Task-oriented • Context sensitive ‘Actions’ pane • Tabs are replaced with Icons • Allows IIS & and ASP.NET configuration • Icons instead of tabs • Provides managed extensibility • Add new management and IIS features • Application configuration can integrate into UI • View health and diagnostics within the UI • Built in remote administration over https • Manage 1 or 1000’s of sites

11. .NET Integration

12. Integrated Application Pool • Application Pool architecture based on IIS 6 • Familiar settings for recycling, health monitoring, and process identity are unchanged • Two pool types in IIS 7 • Integrated (default) • Allows use of managed code to provide pipeline services for all requests • Example: .NET Forms authentication for Perl • Classic • Works same as IIS 6 • Ensures .NET compatibility

13. aspnet_isapi.dll Authentication Forms Windows … ASPX Map Handler Trace … … IIS6 ASP.NET Integration • ISAPI-based Implementation • Only sees ASP.NET requests • Feature duplication Authentication NTLM Basic Anon … Determine Handler CGI Static File ISAPI … Send Response Log Compress

14. IIS7 ASP.NET Integration Basic • Two App Pool Modes • Classic (IIS 6) • Integrated Mode • .NET modules / handlers plug directly into pipeline • Process all requests • Full runtime fidelity Anon Authentication Authorization ResolveCache aspnet_isapi.dll … Static File Authentication ExecuteHandler Forms Windows … … ISAPI ASPX Map Handler UpdateCache Trace SendResponse Compress … … Log

15. Better Management

16. Moved from Metabase.xml (and .bin) to Applicationhost.config File based configuration improves manageability XML – integrate with XML readers and APIs Config can be copied to other servers Easier to read Facilitates backup, restore and editing You now have choices about how to manage IIS configuration Centralized Configuration Delegated Administration Shared Configuration IIS 7 Configuration System

17. Contso.com root Configuration System.NET + IIS7 Contoso.com \ Orders Site RootWeb.config .NET Framework Global web.config Machine.config <system.web>.NET settings .. .. .. <system.webServer>IIS7 Delegated settings .. ASP.net global settings NET global settings IIS 7 Applicationhost.config Global settings and location tags

18. Remote Administration Use IIS Manager from XP, Vista, Windows Server 2003/2008 Auto-deployment and hide Delegated Administration Delegate control to site owners without elevated priviledges Extremely granular: Require Windows Authentication - let site owner control turn on/off Basic Shared Configuration All administration tools are redirected to a common UNC path AppCmd Improved Administration

19. AppCmd simple cmd-line syntax powerful mgmt objects inline help & multiple outputs

20. Appcmd – Listing and Filtering C:\> appcmd list sites SITE "Default Web Site" (id:1,bindings:HTTP/*:80:,state:Started)SITE "Site1" (id:2,bindings:http/*:81:,state:Started)SITE "Site2" (id:3,bindings:http/*:82:,state:Stopped) C:\> appcmd list requests REQUEST "fb0000008000000e" (url:GET /wait.aspx?time=10000,time:4276 msec,client:localhost) C:\> appcmd list requests /apppool.name:DefaultAppPool C:\> appcmd list requests /wp.name:3567 C:\> appcmd list requests /site.id:1 Filter results by application pool, worker process, or site

22. Built in Request Tracing

23. View Detailed Errors in the Browser New errors provide prescriptive guidance Access Runtime State Info in Real-Time New APIs expose all runtime diagnostic information Ex. See all currently executing requests Rapidly Troubleshoot Faulty Applications Rules define ‘failures’ that triggers report of pipeline events Define by http result code and/or time taken Configurable per application or URL Quickly identify bottlenecks Developers can add custom events Tracing and Diagnostics

25. Security

26. Security Progress for IIS Two security patches for IIS 6 since RTM (>3 yrs) 2005 2006 2004 2002 2003 4/15Server2003 RTM (WebDAVDoS) (ASP) 06/11 06-034 10/12 04-021 IIS6 4/1002-018 6/1102-028 10/30 02-062 5/2803-018 IIS 5 8 4 4 7/13 04-021 IIS 4 4 8 4 < Critical • Notes • MS02-011 & 012 not included: updates SMTP service only • ASP.NET adds: 1 – v 2.0 2 - v 1.1 3 - v 1.0 = Critical = Rollup with X updates X

27. IIS 6: No Critical fixes since RTM

28. Building on a Solid Foundation:IIS 7 Security Features

29. URLAuthorization • Control access to sites, folders, or files without using NTFS • Inspired by ASP.net URL authorization, but designed for administrators • Rules are stored in .config files • Delegate control to store in web.config • Authorization rules are then portable • Xcopy and maintain security

30. Request Filtering • Very strong security feature e.g. • Prevent URLs that contain “any string” • Block URLs over “X” in length • Prevent delivery of “.config” or “/bin” • Easy to read rules stored in .config • Delegate control to store in web.config • Filtering rules are then portable • http://www.iis.net/default.aspx?tabid=2&subtabid=25&i=1040

31. demo URL Authorization and Request Filtering

32. Summary • Most extensible yet • Modular, IIS Manager, .NET • Most .NET friendly yet • Integrated pipeline, shared web.config • Most manageable yet • Simplified deployment, server farms, administration • Xcopy of config files, shared config, appcmd • Easier to troubleshoot • Most secure yet • Reduced attack surface, .NET Integration for Auth, Application Pool Isolation • URLAuthorization and Request Filtering
