3. SECURITY 
There are different levels of access control for the Remote I/O control: message 
identifier, password, and authorised numbers. Also the aliases defined for 
commands increase security.  
You must use a message identifier, which means that you must name the Nokia 
12 GSM Module to be able to use the Remote I/O control. Each control 
message begins with an identifier, which enables the Nokia 12 GSM Module 
recognise it as a Remote I/O control message. Enter the identifier with the 
Nokia 12 Configurator software when using the Nokia 12 GSM Module for the 
first time (see chapter 4.5). Only users who know the correct message identifier 
can control and monitor the device attached to the Nokia 12 GSM Module. The 
message identifier is case sensitive. 
You can use a password to further secure the communication between the 
mobile phone and the Nokia 12 GSM Module. You must enter the password 
when sending a control message to the Nokia 12 GSM Module. Set the 
password with Configurator or with a control message (see chapter 5.2). Only 
users who know the correct password can control and monitor the device 
attached to the Nokia 12 GSM Module. The password is case sensitive. 
You can also determine a closed user group of up to 16 authorised phone 
numbers. The Nokia 12 GSM Module only accepts control messages from 
these phone numbers. Specify the numbers with Configurator. The first number 
on the authorised phone number list is in bold and it identifies the main user of 
the Nokia 12 GSM Module. The main user is notified of any unauthorised 
control attempts. 
You can use user-defined commands (aliases) instead of the default 
commands of the Nokia 12 GSM Module (see chapter 5.3). If an alias has been 
defined, the default command can no longer be used and is not accepted as 
part of a control message. While default commands are generally known, an 
alias is only known by the one who defined it. Only users who know the correct 
alias can control and monitor the device attached to the Nokia 12 GSM Module. 
 
Note: The message identifier and password are case sensitive, whereas 
commands and aliases are not.
