16.5.3 HT T PS
You can set the Zyxel Device to use HTTP or HTTPS (HTTPS adds security) for Web Configurator sessions.
HTTPS (HyperText Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is a web protocol that
encrypts and decrypts web pages. Secure Socket Layer (SSL) is an application-level protocol that
enables secure transactions of data by ensuring confidentiality (an unauthorized party cannot read the
transferred data), authentication (one party can identify the other party) and data integrity (you know if
data has been changed).
It relies upon certificates, public keys, and private keys (see
information).
HTTPS on the Zyxel Device is used so that you can securely access the Zyxel Device using the Web
Configurator. The SSL protocol specifies that the HTTPS server (the Zyxel Device) must always
authenticate itself to the HTTPS client (the computer which requests the HTTPS connection with the Zyxel
Device), whereas the HTTPS client only should authenticate itself when the HTTPS server requires it to do

optional and if selected means the HTTPS client must send the Zyxel Device a certificate. You must apply
for a certificate for the browser from a CA that is a trusted CA on the Zyxel Device.
Please refer to the following figure.
1
HTTPS connection requests from an SSL-aware web browser go to port 443 (by default) on the Zyxel
Device's web server.
2
HTTP connection requests from a web browser go to port 80 (by default) on the Zyxel Device's web
server.
