Browser security
Security features may be required for some services, such as online banking or
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.
Security module
The security module improves security services for applications requiring a browser
connection, and allows you to use a digital signature. The security module may
contain certificates as well as private and public keys. The certificates are saved in
the security module by the service provider.
To view or change the security module settings, select Menu > Settings >
Security > Security module sett..
Certificates
Important: 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. You may receive these certificates from your service provider.
Authority certificates and user certificates may also be saved in the security
module by the service provider.
To view the list of the authority or user certificates downloaded into your phone,
select Menu > Settings > Security > Authority certificates or User certificates.
