CHAPTER 20 Web Authentication 20.1 Overview Web authentication intercepts all network traffic, regardless of address or port, until the user authenticates his or her connection, usually through a specifically designated login web page. This means all web page requests can initially be redirected to a special web page that requires users to authenticate their sessions. Once authentication is successful, they can then connect to the rest of the network or Internet. As soon as a user attempt to open a web page, the UAG reroutes his/her browser to a web portal page that prompts he/she to log in. Figure 143 Web Authentication Example The web portal page only appears once per authentication session. Unless a user session times out or he/she closes the connection, he or she generally will not see it again during the same session. Use web authentication policies to control who can access the network. You can authenticate users (require them to log in) and even perform Endpoint Security (EPS) checking to make sure users' computers comply with defined corporate policies before they can access the network. After a user passes authentication the user's computer must meet the endpoint security object's Operating System (OS) option and security requirements to gain access. See Chapter 38 on page 419 for how to configure endpoint security objects to use with authentication policies. In the following figure the UAG's authentication policy requires endpoint security checking on local user A. A passes authentication and the endpoint security check and is given access. Local user B passes authentication but fails the endpoint security check and is denied access. UAG715 User's Guide 223

Web Authentication
20.1
Overview
Web authentication intercepts all network traffic, regardless of address or port, until the user
authenticates his or her connection, usually through a specifically designated login web page. This
means all web page requests can initially be redirected to a special web page that requires users to
authenticate their sessions. Once authentication is successful, they can then connect to the rest of
the network or Internet.
As soon as a user attempt to open a web page, the UAG reroutes his/her browser to a web portal
page that prompts he/she to log in.
Figure 143
Web Authentication Example
The web portal page only appears once per authentication session. Unless a user session times out
or he/she closes the connection, he or she generally will not see it again during the same session.
Use web authentication policies to control who can access the network. You can authenticate users
(require them to log in) and even perform Endpoint Security (EPS) checking to make sure users’
computers comply with defined corporate policies before they can access the network. After a user
passes authentication the user’s computer must meet the endpoint security object’s Operating
System (OS) option and security requirements to gain access. See
Chapter 38 on page 419
for how
to configure endpoint security objects to use with authentication policies.
In the following figure the UAG’s authentication policy requires endpoint security checking on local
user
A
.
A
passes authentication and the endpoint security check and is given access. Local user
B
passes authentication but fails the endpoint security check and is denied access.
