Security considerations
Java™ is an effective way of offering powerful applications on mobile phones. It allows a mobile phone's integrated features
to be used via applications or games downloaded "over the air" (multimedia playback, network access…).
Your phone is equipped with a sophisticated access control system in order to protect your data and airtime.
The access control system comprises 2 security subsystems:
- Network access (GPRS/GSM communications, HTTP/Web connections…)
- Automatic startup (activation of the application at predefined intervals)
The "Network access" security subsystem has 3 possible authorization levels. These levels are listed from the most restrictive
to the most permissive:
- Never - This authorization level prevents all access to protected features.
- Confirm - The user is prompted to grant access authorization to protected features each time the application is run
- Always - This authorization level automatically grants access to protected features without restriction.
The "Auto. Startup" security subsystem has 2 authorization levels:
- Activate: the application will start up automatically at predefined intervals
- Deactivate: the application will not start up automatically.
Security configuration menu
When an application is installed on the mobile phone, the different "Network access" security authorizations are displayed
and can be selected by the user. The security configuration of the "Network access" subsystem can be modified via the
application's "Settings/Security" menu.
When you enter the "Security" menu, the application's security status is displayed (see "Security considerations" in the
paragraph above).
If you do not wish to enter this menu, simply select the "Back" button.
To proceed, select the "
OK " button.
The menu displayed allows you to increase or decrease the authorization levels applied to the current application.
Similarly, the security configuration of the "Auto. startup" subsystem can be altered via the application's "Settings/Auto.
Startup" menu.
