Browser security Security features may be required for some services, such as banking services or online shopping. For such connections you need security certificates and possibly a security module, which may be available on your SIM card. For more information, contact your service provider.

The security module can contain certificates as well as private and public keys. The certificates are saved in the security module by the service provider. To change the security module settings, press Menu, and select Services → Settings → Security settings → Security module settings. • Security module details - to view the security module title, its status, manufacturer, and serial number. • Module PIN request - to set the phone to request the module PIN when you use services provided by the security module. • Change module PIN - to change the module PIN, if allowed by the security module. Enter the current module PIN code, then enter the new code twice. • Change signing PIN - to change a signing PIN. Select the signing PIN that you want to change. Enter the current PIN code, then enter the new code twice. See Access codes on page 10. Certificates 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. There are three kinds of certificates: server certificates, authority certificates, and user certificates. • Server certificates are for creating a connection with improved security to the content server. The phone receives the server certificate from the content server before the connection is established and its validity is checked using the authority certificates saved in the phone. Server certificates are not saved. The security icon does not indicate that the Copyright © 2004 Nokia. All Rights Reserved. 59
