Glossary
stack Two to four connected devices that share detection resources.
stacking A feature that allows you to increase the amount of traffic inspected on a network
segment by connecting two to four physical devices in a stacked configuration.
When you establish a stacked configuration, you combine the resources of each
stacked device into a single, shared configuration.
switch A network device that acts as a multiport bridge. Using network discovery, the
system identifies switches as bridges. In addition, you can configure managed
devices as virtual switches, performing packet switching between two or more
networks.
switched interface An interface that you want to use to switch traffic in a Layer 2 deployment. You
can set up physical switched interfaces for handling untagged VLAN traffic, and
logical switched interfaces for handling traffic with designated VLAN tags.
system policy Settings that are likely to be similar for multiple appliances in a deployment, such
as mail relay host preferences and time synchronization settings. Use the
Defense Center to apply a system policy to itself and its managed devices.
table view A type of workflow page that displays event information, with one column for
each of the fields in the database table. When performing event analysis, you can
use drill-down pages to constrain the events you want to investigate before
moving to the table view that shows you the details about the events you are
interested in. The table view is often the next-to-last page in workflows delivered
with the system.
tap mode An advanced inline set option available on 3D9900 and Series 3 devices where a
copy of each packet is analyzed and the network traffic flow is undisturbed
instead of passing through the device. Because you are working with copies of
packets rather than the packets themselves, the device cannot affect the packet
stream even if you configure access control and intrusion policies to drop, modify,
or block traffic.
task queue A queue of jobs that the appliance needs to perform. When you apply a policy,
install software updates, and perform other long-running jobs, the jobs are
queued and their status reported on the Task Status page. The Task Status page
provides a detailed list of jobs and refreshes every ten seconds to update their
status.
transparent inline
mode
An advanced inline set option that allows a device to act as a “bump in the wire”
and to forward all the network traffic it sees, regardless of its source and
destination.
URL category A general classification for a URL, such as malware or social networking.
URL filtering A feature that allows you to write access control rules that determine the traffic
that can traverse your network based on URLs requested by monitored hosts,
