Device OUI Score

The Organizationally Unique Identifier (OUI) score is based on the LAN MAC address of a device. RAPIDS can be

configured to poll your routers and switches for the bridge forwarding tables. RAPIDS then takes the MAC addresses

from those tables and runs them through a proprietary database to derive the OUI score. The OUI score of each device is

viewable from each rogue’s detail page. Table 100 provides list the OUI scores definitions.

Score Description

Score of 1 Indicates any device on the network; this is the lowest threat level on the network.

Score of 2

Indicates any device in which the OUI belongs to a manufacturer that produces wireless (802.11)

equipment.

Score of 3

Indicates that the OUI matches a block that contains APs from vendors in the Enterprise and small

office/ small home market.

Score of 4

Indicates that the OUI matches a block that belonged to a manufacturer that produces small

office/ small home access points.

Device OUI Scores

Rogue Device Threat Level

The threat level classification adds granularity for each general RAPIDS classification. Devices of the same classification

can have differing threat scores based on the classifying rule, ranging from 1 to 10 with a default value of 5. This

classification process can help identify the greater threat. Alerts can be defined and sorted by threat level.

Threat level and classification are both assigned to a device when a device matches a rule. Once classified, a device’s

classification and threat level change only if it is classified by a new rule or is manually changed. Threats levels can be

manually defined on the RAPIDS > Detail page when the RAPIDS classification is manually overridden or you can edit

the rule to have a higher threat level.

Viewing and Configuring RAPIDS Rules

To view the RAPIDS rules that are currently configured on AirWave, navigate to the RAPIDS > Rules page (Figure
