Sun Java System Web Proxy Server  9
Chapter 1: Introduction
 Filtering Service: Interacts with the Sun Java System Web Proxy Server
and Network Agent to filter internet requests. Filtering Service either
permits the internet request or sends an appropriate block message to the
user.
 Websense Manager: Administrative interface that allows you to
configure and manage Websense functionality through the Policy Server.
Websense Manager is used to define and customize internet access
policies, add or remove clients, configure Policy Server, and much more.
 User Service: Communicates with directory services in your network to
allow you to apply filtering policies based on users, groups, domains, and
organizational units.
 Network Agent: Manages the internet protocols that are not managed by
the Sun Java System Web Proxy Server. Detects HTTP network activity
and instructs the Filtering Service to log this information. You must install
Network Agent and configure it properly to use the Bandwidth Optimizer,
Protocol Management, and IM Attachment Manager features, and to log
the number of bytes transferred and duration of transfer. Network Agent
is also used to manage HTTP, HTTPS, and FTP filtering for a Stand-
Alone (non-integrated) Websense installation.
 Usage Monitor: Tracks users’ internet activity and sends alerts to
Websense administrators when configured threshold values are crossed.
 DC Agent: An optional component that transparently identifies users who
authenticate through a Windows
®
directory service. DC Agent enables
filtering of internet requests according to policies assigned to particular
users or groups.
 RADIUS Agent: An optional component that works through a RADIUS
Server to transparently identify users and groups who access your
network using a dial-up, Virtual Private Network (VPN), Digital
Subscriber Line (DSL), or other remote connections.
 eDirectory Agent: An optional component that works together with
Novell
®
eDirectory™ to transparently identify users so that Websense
can filter them according to particular policies assigned to users or
groups.
 Logon Agent: An optional component that works with a Websense client
application (
LogonApp.exe) to transparently identify users as they log
on to a Windows domain via client machines. Logon Agent can be used
with a Windows NT
®
-based directory service or with Active Directory
®
,
which is LDAP-based. Logon Agent receives its user information from
