Locking Down a Mobile Computer
Like most configuration options in Windows Mobile 6, security settings are set via XML provisioning. For example, 
to enforce the “trusted” model and only allow applications signed with a privileged certificate to run, use the 
following provisioning document:
<wap-provisioningdoc>
<characteristic type=”SecurityPolicy”> 
<!-- Disallow unsigned apps -->
<parm name= “4102” value= “0”/> 
<!-- No Prompt -->
<parm name= “4122” value= “1”/> 
</characteristic>
</wap-provisioningdoc> 
For more information on various security options, refer to the Security Policy Settings topic in the latest Windows 
Mobile documentation.
