In securing your SharePoint Workspace environment, it’s important to understand the encryption story.  The table below summarizes built-in data encryption in SPW 2010:

* This includes files in the Documents and Files tools, as well as file attachments in all other tools.

*** Data sent over the network between the SharePoint Workspace and the SharePoint servers can be encrypted using SSL, configurable by the server administrator.

On a related note, SharePoint Workspace 2010 supports all three authentication flavors available in SharePoint Server 2010: Single Sign-On, Forms-Based Authentication, and Claims-Based Authentication.  You can go here to see Paul Cannon’s post on Single Sign-on.
