System Timeout; Introduction To Https - ZyXEL Communications ZyWALL 1050 User Manual

ZyWALL 1050 User's Guide

35.1.2 System Timeout

There is a lease timeout for administrators. The ZyWALL automatically logs you out if the
management session remains idle for longer than this timeout period. The management session
does not time out when a statistics screen is polling.
Each user is also forced to log in the ZyWALL for authentication again when the
reauthentication time expires.
You can change the timeout settings in the User/Group screens.

35.2 Introduction to HTTPS

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 can securely access the ZyWALL using the web
configurator. The SSL protocol specifies that the HTTPS server (the ZyWALL) must always
authenticate itself to the HTTPS client (the computer which requests the HTTPS connection
with the ZyWALL), whereas the HTTPS client only should authenticate itself when the
HTTPS server requires it to do so (select Authenticate Client Certificates in the WWW
screen). Authenticate Client Certificates is optional and if selected means the HTTPS 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 web server.
2 HTTP connection requests from a web browser go to port 80 (by default) on the
ZyWALL's web server.
