Because increasing numbers and types of mobile devices-such as laptops, PDAs, and Tablet PCs (along with older technologies, such as floppy disks)-will be connecting to your SharePoint sites, you need to define what types of devices can permanently hold your mission-critical information. The last thing you want is a member of the Compensation Committee Site downloading sensitive information to an unsecured PDA and then leaving that device in an airport or hotel. It would be an understatement to say that this is an undesirable scenario for any organization. In addition, with SharePoint Server 2007 having mobile URLs for every list in the farm, the mobile capabilities of this product have increased over previous versions. Therefore, you should consider the following issues when determining how your mission-critical, private, secret, or sensitive information is stored:
Outline acceptable use of mobile devices.
Prohibit storage of sensitive information on mobile devices.
Define what a mobile device is.
Mobile devices must store all information in encrypted form.
Mobile devices must be password-protected.
Establish default permissions for all files on the network.
Prohibit write-down permissions for company information.
Information ownership must be assigned.
Prohibit taking ownership of information without authorization.
