Glossary: 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, or
•
want to minimize the risk of viruses or other malicious software and
be sure of the authenticity of software when downloading and
installing software.
Glossary: Authority certificates are used by some services, such as
banking services, for checking signatures or server certificates or
other authority certificates.
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.
Glossary: User certificates are issued to users by a Certifying
Authority.
