CHAPTER 1: INTRODUCTION FILTERING ELEMENTS
18 8E6 TECHNOLOGIES, R3000 ENTERPRISE FILTER AUTHENTICATION USER GUIDE
Service Ports
Service ports are used when setting up filter segments on
the network (the range of IP addresses/netmasks to be
detected by the R3000), the global (default) filtering profile,
and the minimum filtering level.
When setting up the range of IP addresses/netmasks to be
detected, service ports can be set up to be open (ignored).
When creating the global filtering profile and the minimum
filtering level, service ports can be set up to be blocked or
filtered.
Examples of service ports that can be set up include File
Transfer Protocol (FTP), Hyper Text Transfer Protocol
(HTTP), Network News Transfer Protocol (NNTP), Secured
HTTP Transmission (HTTPS), and Secure Shell (SSH).
Rules
A rule is comprised of library categories to block, leave
open, or include in a white list. Each rule that is created by
the global administrator is assigned a number. A rule is
selected when creating a filtering profile for an entity.
Minimum Filtering Level
The minimum filtering level consists of library categories set
up at the global level to be blocked or opened, and service
ports set up to be blocked or filtered. If the minimum filtering
level is created, it applies to all users in IP, NT, and LDAP
groups, and takes precedence over filtering settings made
for group and member filtering profiles.
The minimum filtering level does not apply to any user who
does not belong to a group, and to groups that do not have
a filtering profile established.
