The other tab contains all settings that are not related to the
device or connections. This is also where settings from system
components and add-ons, developed by third-party developers,
will be found.
Certificate manager
Digital certificates ensure that the Web or WAP pages you visit,
or any software you install, really are created by the person you
expect.
Certificates may be present on the pages that you view or the
software that you download. Your P900 compares these
certificates with a set of certificates that are stored in
Certificate
manager
to ensure the authenticity of the page or software. If the
certificates do not match, your P900 informs you, and gives you
the following choices:
• Prevent the page being loaded or the software being installed.
• Continue at your own risk.
The certificates on your P900 have been created and issued by
an independent organisation that ensures their authenticity.
Security information
Security information is displayed when
Certificate manager
cannot be sure of the origin of the page or software. For
example, security information will be displayed if:
• The certificate on a page has expired.
• The identity of a software manufacturer cannot be verified.
Security information is also displayed when a certificate on your
P900 has:
• Expired.
• Been revoked by the independent organisation that issued it.
Adding and deleting certificates
Your P900 handles certificates automatically so, most of the
time, you can browse the Internet securely without using
Certificate manager
. If you do need to add or delete a certificate,
you will usually be informed by your network operator or
system administrator. You should delete a certificate from
Certificate manager
if you are informed, or suspect, that:
• The certificate does not belong to the person who supplied it.
• The certificate was issued incorrectly by the independent
organisation that created it.
