Description

S60 3rd Edition and S60 3rd Ed, FP1 devices impose heavy requirements for messaging DLLs in terms of platform security capabilites.

Solution

All client-side MTM components (Client MTM, UI MTM, and UI Data MTM DLLs) need to have ALL -TCB capabilities because they can be loaded by any application that can have any set of capabilities from that capability space.

A server-side MTM component, that is, an MTM DLL loaded by the messaging server, requires capabilities equal to the loading process. The server-side MTM component should have exactly these capabilities:

ReadDeviceData
WriteDeviceData
ProtServ
NetworkControl
 
 
NetworkServices
LocalServices
ReadUserData
WriteUserData

Given these heavy capability requirements, any (client-side) MTM implementation has to go through the Symbian Signed process and get manufacturer approval.
