Our Device Management and Security (DMSec) team recently produced a series of security booklets. These were very well recieved at the MEDC 2007 event last week. So I'd like to point out that these are also available online. Among the topics you will find:
There are 2 booklets available online:
Security Considerations for Windows Mobile Messaging in the Enterprise
Security Model for Windows Mobile 5.0 and Windows Mobile 6
Bookmark these great resources and read them when you want an in depth look at the Windows Mobile security model - either as a developer or an IT administrator.
