- Messaging receive (SMS,SMS-CB interception by a

According to the security status of an installed MIDlet (see
below), each of these security groups has one among 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. This means that the mobile phone
successfully authenticated the named party as the source
of the MIDlet.
Security permissions are different for "uncertified" or
"certified" MIDlets, and may be different for different sorts of
named parties. Usually "uncertified" security permisions are
more restrictive than "certified" ones.
-) ))
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 (see "Security considerations"
paragraph above).
If you do not want to enter the security menu, simply select
"Back" button.
You can proceed by selecting "Ok" button.
The menu displayed allows you to increase or decrease
permissions currently applied to the current MIDlet for each
of the security groups.

The maximum risk exposure increase is limited by the
security status. Depending of the manufacturing
configuration, it means, for example, that "Net Access"
security group authorization cannot be set to a permissive
