Each of these security groups has one of 5 possible
authorizations levels (listed from the more restrictive to the
more permissive):
- Never: The security group completely prevents access to the
protected features.
- Per use: Each time MIDlet tries to use protected feature, user
is prompted to grant access.
- Per session: First time a MIDlet uses a protected function,
user is prompted to grant access like in "Per use"
authorization but access is granted until the MIDlet
terminates.
- Single confirmation: The first time in the whole MIDlet life a
MIDlet uses a protected feature, user is prompted to grant
access. It remains valid until the MIDlet is removed from the
handset.
- Always: The security group unconditionally grants access to
protected features.
A MIDlet has a security status which is either "uncertified", or
else "certified".
An "uncertified" status means that the source of the MIDlet
could not be verified by the mobile phone at installation time. As
far as the phone knows, the MIDlet could have been written by
anyone.
A "certified" status means that the MIDlet was digitally signed by
a known party, whose name is displayed by the mobile phone.
Security permissions are different for "uncertified" or "certified"
MIDlets.
Security configuration menu
When a MIDlet is installed in the mobile phone, default security
authorizations are applied.
This default security configuration may be altered through the
"Settings/Security" menu of an installed MIDlet.
Once in the "Security" menu, the security status of the MIDlet is
displayed.
