Nokia 9500 - Manual (Page 65)

• Allow remote locking — If you set this option to Yes , you can lock the device by sending a predefined text message from
another phone.
To create a remote locking message, select Security > Device security . Set the option Allow remote locking to Yes , enter your
lock code, and enter text for the remote locking message in the Message field. Confirm the message, and press Done . The remote
locking message is case-sensitive and can be 5 to 20 characters or digits long. Press Reboot to restart the device and for the
changes to take effect.
Tip: If you use a memory card with no password, the memory card will be locked when you lock your device with the
remote locking message. To remove the memory card password, select Desk > Office > File manager , press Menu,
and select Memory card > Security > Remove password... . Enter the remote locking message as your password, and
press Remove . If the remote locking message is longer than 8 characters, the first 8 characters of the message are used
as the memory card password.
Defining PIN code settings
To define PIN code settings, select
Security > Device security , and select the PIN codes page.
Define the following:
•
PIN code request — If you set this option to On , the PIN code is requested each time the phone is switched on. Note that this
setting cannot be changed if the phone is switched off or if there is no valid SIM card inserted. Note also that some SIM cards
do not allow you to turn off the PIN code request.
• PIN code — Press Change to change the PIN code. The PIN code must be 4 to 8 digits long. Changing the PIN code requires
that PIN code request is selected, the device is on, and that there is a valid SIM card inserted.
• PIN2 code — Press Change to change the PIN2 code. The PIN2 code must be 4 to 8 digits long. The PIN2 code is required to
access some functions, such as the fixed dialing settings, which must be supported by your SIM card.
Changing the restriction password
To change the password used for restricting voice, fax, and data calls, select
Security > Device security , and select the Call
restriction page. Select the Restriction password field, and press Change . Enter the current code, and then the new code twice.
The restriction password must be four digits long.
Certificate manager
Important: Note that even if the use of certificates makes the risks involved in remote connections and software
installation considerably smaller, they must be used correctly in order to benefit from increased security. The existence
of a certificate does not offer any protection by itself; the certificate manager must contain correct, authentic, or trusted
certificates for increased security to be available. Certificates have a restricted lifetime. If Expired certificate or Certificate
not valid yet is shown even if the certificate should be valid, check that the current date and time in your device are
correct.
Before changing any certificate settings, you must make sure that you really trust the owner of the certificate and that
the certificate really belongs to the listed owner.
Digital certificates may be used for:
• connecting to an online banking service or another site or remote server to transfer confidential information
• reducing the risk of viruses or other malicious software, and checking the authenticity of software when downloading and
installing it
Managing certificates
Personal certificates are certificates that are issued to you. They are listed on the
User page.
Authority certificates are on the Other page. They are used by some services, such as banking, for checking the validity of other
certificates.
To add certificates, select
Security > Certificate manager . Press Add to add a new certificate. You can then browse for the
certificate file. Press Delete to remove a selected certificate.
To check the authenticity of a certificate, select Security > Certificate manager . Select a certificate, and press View details . The
Issued to: field identifies the owner of this certificate. Make sure that this is the name of the party to whom the certificate
belongs. The Fingerprint: field uniquely identifies the certificate. Contact the help desk or customer service of the owner of the
certificate and ask for the MD5 fingerprint of the certificate. Compare the fingerprint with the one shown in the dialog to check
whether they match.
Tip: Check the authenticity of a certificate each time you add a new certificate.
To change the trust settings of a certificate, select Security > Certificate manager . Select the certificate, press View details , and
press Trust settings . Depending on the certificate, a list of the applications that can use the selected certificate is shown. Select
an application field, and change the value to Yes or No . Note that you cannot change the trust settings of a personal certificate.
