Some SHAREPOINT Questions Part 3

What are the security improvements in SharePoint 2010

In SharePoint 2010 a variety of security methods have been introduced.

Claims-Based Authentication - Claims based authentication is based on identity. and trust.

Code Access Security - in which you can specify your own code access
security (CAS) policy for your web parts.

Sandbox Solutions - Sandbox Solutions which when deployed to the server, SharePoint runs in a special process that has limited permissions.

Cross-Site Scripting - Introduced to prevent Cross - Site Scripting (XSS) attacks.

What are SharePoint Sandboxed soultions

SharePoint 2010 provides a new sandboxed environment that enables you to run user solutions without affecting the rest of the SharePoint farm. This environment means that users can upload their own custom solutions without requiring intervention from administrators, and without putting the rest of the farm at risk. This means that the existing sites\pages or components will not be effected by the newly added soultion.

What Changes are made in SharePoint 2010 to enforce Referential Integrity

In SharePoint 2010, Referential Integrity is enforced using two options, available with Look-up columns.

While creating a Look-up column, you can either choose:

a) Restrict Delete or

 b) Cascade Delete 

to define a relationship between the Look-up list and the list containing the look-up Column.

What Has Changed with SSP in SharePoint 2010

In SharePoint 2010 Shared Service Providers (SSP's) are replaced by Service Applications. 

Services are no longer combined into a SSP. They are running independent as a service application. 

The service application architecture is now also built into Microsoft SharePoint Foundation 2010, in contrast to the Shared Services Provider (SSP) architecture that was only part of Office SharePoint Server 2007and not wss.

A key benefit here is that all services are installed by default and there is no SSP setup.
