Digital certificates are used to verify the origin of browser pages and installed software. However, they can only be trusted if the origin of the certificate is known to be authentic.

Digital certificates are needed if you want to:

•Connect to an online bank, another site, or remote server for actions that involve transferring confidential information.

•Minimize the risk of viruses or other malicious software and be sure of the authenticity of software when downloading and installing software.

Authority certificates are used by some services, such as banking services, for checking signatures or server certificates or other authority certificates. User certificates are issued to users by a Certifying Authority.

Important: Although 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.

VIEWING CERTIFICATE DETAILS—CHECKING AUTHENTICITY

You can only be sure of the correct identity of a browser gateway or a server when the signature and the period of validity of a browser gateway or server certificate have been checked.
