Managing security settings

Configuring the security settings affect how the device interacts with the end user when the application is accessing sensitive operations. For example, the end user may allow a certified application to establish network connections without prompting.

When an application is installed, its security settings (permissions granted to it) are set to their defaults based on the protection domain the application is bound to. Nokia devices provide a settings view, with which the security settings are configured by the end user after installation. In Symbian the devices settings view is found from Application Manager. In Series 40 Application Access Settings are used. Select the MIDlet and then select Options –> App. Access menu. This has Communication, Phone Access, and Auto start sub menus where the settings can be changed as desired.

The Security warnings setting can be changed to User defined mode in the Symbian device N8 in the following way: Settings —> Application mgr. —> Installed apps. -> scroll to MIDlet suite and long tap -> choose Suite settings-> tap Security warnings (User defined mode) .

When an application is upgraded in Symbian, the settings configured by the user are retained. In Series 40 settings are reset to their defaults.

Series 40 behaves according to the User defined mode. The Default mode found in Java Runtime 2.1 for Symbian is not implemented.
