WRT 1.0 and later support the following security policy.
The security management of widgets running on S60 mobile devices is +based on a sandbox security model. Specifically:
Widgets do not need to be signed.
All widgets are currently considered untrusted by the device +platform. This means that access to platform services (such as user data) +is controlled and that mobile device users must grant permission before a +widget can access network services.
Widgets access the network through the Web Browser for S60.
Widgets access S60 platform services through scriptable plugins +or Javascript Service APIs (see below for a list of plugins and Service APIs). + For WRT 1.0, the Web Runtime controls access to platform services through +the Web Browser for S60. Starting in WRT 1.1, the Web Runtime utilizes a +common component called the Runtime Security Manager to enable access control +to platform services. For more information, see section Runtime Security Manager.
