Introducing IIS 7.0 Pillars
5
IIS 7.0 - Security
Security

• SD³
• Componentized web server
• 40 (!) setup components
• Lower the attack surface
• Reduction of patch management
• URLScan functionality built-in

• Componentization in action

7
IIS 7.0 - Extensibility
Extensibility

• New APIs
• Win32 API
• Used by core IIS 7.0 components (modular)
• No rabbits in hats ?
• Managed code API
• Integrated pipeline with ASP.NET 2.0
• Transfer your knowledge (IHttp interfaces)
• ISAPI the easy way
