Endpoint Fingerprints

FortiNAC continuously collects identity records as hosts connect to the network. These records are used to rapidly identify and categorize new devices as they connect to the network. A list of these device identity matches are displayed on the Endpoint Fingerprint view. A separate record is added every time a new fingerprint is heard for a MAC. For example, if the adapter on a host is moved from a registration VLAN to a production VLAN and as a result requests a new IP address this creates a new record. If two records are displayed for the same MAC and port, but with different OSs, the host is most likely a dual-boot host. This generates the Device Fingerprint Changed event. The following information can be found for each fingerprint.

Information

Field

Definition

Physical Address

MAC address of the device.

Device Type

Indicates the type of hardware detected.

Operating System

Operating system of the host. If more than one record is displayed with different operating systems, this host may be dual boot.

IP Address

IP address of the device.

Host Name

The name for this host extracted from the DHCP packet.

Vendor

Manufacturer of the host. This is based on the vendor OUI.

Vendor OUI

First 3 octets of a device’s Physical Address.

Source

Method used to identify the device. Sources can be ranked through Set Source Rank.

Rule Name

Name of the Device Profiling Rule that was a match for this device.

Device Registered

Specifies whether the device is registered in the FortiNAC Database or is a rogue device. The number of devices registered or rogue will display above the table header.

Last Heard

The last time FortiNAC matched this fingerprint for this host.

Creation Time

The first time FortiNAC matched this fingerprint for this host.

The information displayed on the table can be configured by hovering over the table's header to reveal a settings icon on the left side of the header.

Along the top of the Endpoint Fingerprint view, interactable charts can be displayed for Device Types, Operating System, Vendor, Vendor OUI, and Source. Hovering over the charts will reveal a settings icon at the top left of the view. Clicking it will provide the option to customize the charts. Charts can be reordered by dragging and dropping the chart to its desired location along the top. Selecting a slice of a chart will filter the fingerprints by that attribute. To remove the filter, click the filter icon to the top right of the chart.
