public access
zone:
|
|
-access from zone to network controlled by
public access controller
|
|
-public access controller pac tries to be
independent of clients, solutions available at least from Cisco and Nokia
|
|
-by default pac doesn’t let any user traffic
through (maybe dns etc.)
|
|
-capture user web page retrieval request,
returns the authentication page or http redirect as response
|
|
-user fills authentication information on web
form
|
|
-public access controller verifies the
authentication information from user database
|
|
-if authentication correct, the pac opens a
”hole” to its firewall rules to the IP address user is using
|
|
-the user now has free or restricted (by
firewall rules in pac) connection to Internet
|
|
|
