hardware specifications and safety and regulatory information for Sourcefire
appliances.
TIP! You can host virtual Defense Centers and devices, which can manage and
be managed by physical appliances. However, virtual appliances do not support
any of the system’s hardware-based features: redundancy, switching, routing, and
so on. For detailed information, see the Sourcefire 3D System Virtual Installation
Guide.
The topics that follow introduce you to the Sourcefire 3D System and describe its

Sourcefire 3D System Appliances
A Sourcefire appliance is either a traffic-sensing managed device or a managing
Defense Center:
Physical devices are fault-tolerant, purpose-built network appliances available with
a range of throughputs and capabilities. Defense Centers serve as central
management points for these devices, and automatically aggregate and correlate
the events they generate. There are several models of each physical appliance
type; these models are further grouped into series and family.
Many Sourcefire 3D System capabilities are appliance dependent. For more
information, see the following sections:
• Defense Centers on page 9
• Managed Devices on page 10
• Understanding Appliance Series, Models, and Capabilities on page 10
Defense Centers
The Defense Center provides a centralized management point and event
database for your Sourcefire 3D System deployment. Defense Centers, which
can be physical or virtual, aggregate and correlate intrusion, file, malware,
discovery, connection, and performance data. This allows you to monitor the
information that your devices report in relation to one another, and to assess and
control the overall activity that occurs on your network.
