quota
- The number of minutes configured for a passed
library category in an end user’s profile that lets him/her
access URLs for a specified time before being blocked from
further access to that category
Radius
- This feature is used for controlling the filtering
levels of dial-up users. The Radius accounting server deter-
mines which accounts will be filtered and how they will be
filtered. The user profile in the Radius accounting server
holds the filter definition for the user.
Real Time Probe
- On the R3000, this tool is used for moni-
toring the Internet activity of specified users in real time. The
report generated by the probe lets the administrator know
whether end users are using the Internet appropriately.
router mode
- An R3000 set up in the router mode will act
as an Ethernet router, filtering IP packets as they pass from
one card to another. While all original packets from client
PCs are allowed to pass, if the R3000 determines that a
request is inappropriate, a block page is returned to the
client to replace the actual requested Web page or service.
rule
- A filtering component comprised of library categories
set up to be blocked, opened, or always allowed. Each rule
created by the global administrator is assigned a number
and a name that should be indicative of its theme. Rules are
used when creating filtering profiles for entities on the
network.
search engine
- A program that searches Web pages for
specified keywords and returns a list of the pages or
services where the keywords were found.
service port
- Service ports can be set up to blocked.
Examples of these ports include File Transfer Protocol
(FTP), Hyper Text Transfer Protocol (HTTP), Network News
