Summary

This hour looked at SharePoint security in terms of authentication and authorization. Claims based authentication was introduced, and you also saw how to configure claims based authentication. Claims based authentication enables you to use a variety of authentication mechanisms at the same time, which makes it easier for many enterprises to move to SharePoint and use their traditional authentication. The hour also discussed authorization in SharePoint, including the concepts of permissions, permission levels, SharePoint groups, and inheriting permissions. All this makes the SharePoint security model robust and easy to administer. All the tasks mentioned can be achieved through the SharePoint object model, and the hour briefly looked at the important classes in the SharePoint security object model. Security is an important part of SharePoint, and understanding it well will go a long way toward helping you build robust and secure SharePoint applications.
