23.3 The WWW Screen
Use this screen to configure the ZyWALL’s HTTP and HTTPS management settings.
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 ZyWALL is used so that you may securely access the ZyWALL using the web
configurator. The SSL protocol specifies that the SSL server (the ZyWALL) must always
authenticate itself to the SSL client (the computer which requests the HTTPS connection with
the ZyWALL), whereas the SSL client only should authenticate itself when the SSL server
requires it to do so (select Authenticate Client Certificates in the REMOTE MGMT >
WWW screen). Authenticate Client Certificates is optional and if selected means the SSL-
client must send the ZyWALL a certificate. You must apply for a certificate for the browser
from a CA that is a trusted CA on the ZyWALL.
Please refer to the following figure.

1 HTTPS connection requests from an SSL-aware web browser go to port 443 (by default)
on the ZyWALL’s WS (web server).
2 HTTP connection requests from a web browser go to port 80 (by default) on the
ZyWALL’s WS (web server).
