Overview of APM appliances

Appliances can host one or more of the following software components: Management Server, Sniffer, and Archiver. Appliances with a Sniffer component are attached to the customer’s network where they passively monitor Web traffic. Sniffers capture, decrypt, and analyze the Web traffic, and transmit content and metrics to one or more Archivers within the same capture group as the Sniffer. Archivers receive the data from Sniffers, analyze the data, and maintain databases used for searching, reporting, and replay. Archivers send snapshots of collected data to the Management Server for display in top-level APM dashboards.

The following table describes the type of appliances that implement the security features discussed in the rest of this section. Appliances come with a predefined set of software components installed on the appliance. Appliances can be physical appliances (PowerEdge series hardware) or virtual appliances (VMware® vSphere®). Both physical and virtual appliances can exist in the same installation, with some restrictions.

Trust model

The following assumptions are made about the installed environment:

•
When more than one physical appliance is in use, the capture subnet ports are connected by a private cable (one Sniffer to one Archiver) or through a private network (when there is more than one Sniffer or Archiver).
•
An appliance’s control port is connected to the customer’s network. The IP addresses assigned within this network should preferably be private, that is, not directly accessible through the public Internet.
•
Only trusted, authorized personnel have physical access to the PowerEdge servers hosting physical appliances.
•
Only trusted, authorized personnel have user accounts on the appliances.
•
The password for the default setup account on each appliance is changed during the initial setup.
•
The password for the default foglight user in Foglight® is changed during the initial setup.
