APPENDIX D
Importing Certificates
This appendix shows you how to import public key certificates into your web browser.
Public key certificates are used by web browsers to ensure that a secure web site is legitimate.
When a certificate authority such as VeriSign, Comodo, or Network Solutions, to name a few,
receives a certificate request from a website operator, they confirm that the web domain and
contact information in the request match those on public record with a domain name registrar. If
they match, then the certificate is issued to the website operator, who then places it on the site to
be issued to all visiting web browsers to let them know that the site is legitimate.
Many ZyXEL products, such as the NSA-2401, issue their own public key certificates. These can be
used by web browsers on a LAN or WAN to verify that they are in fact connecting to the legitimate
device and not one masquerading as it. However, because the certificates were not issued by one of
the several organizations officially recognized by the most common web browsers, you will need to
import the ZyXEL-created certificate into your web browser and flag that certificate as a trusted
authority.
Note: You can see if you are browsing on a secure website if the URL in your web
browser’s address bar begins with https:// or there is a sealed padlock icon
( ) somewhere in the main browser window (not all browsers show the padlock
in the same location.)
