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 > Web > Settings > Security settings > Authority certificates or User
certificates.
The security indicator is displayed during a connection, if the data
transmission between the phone and the content server is encrypted.
The security icon does not indicate that the data transmission between the gateway and the
content server (or place where the requested resource is stored) is secure. The service
provider secures the data transmission between the gateway and the content server.
