Integrate IoT Security with Cisco WLAN Controllers
Integrate IoT Security through Cortex XSOAR with Cisco
WLAN controllers.
When you integrate IoT Security with Cisco
WLAN controllers, Cortex XSOAR uses XSOAR engines to gather data
from WLAN controllers about wireless access points and their clients.
The data is then shown on the Devices page and Device Details pages
in the IoT Security portal.
An
XSOAR engine makes SSH connections to one or more Cisco controllers
and queries them for access point and client data. The engine then
relays the data over HTTPS to Cortex XSOAR, which forwards it to
the IoT Security cloud where an IoT Security administrator can view
it in the IoT Security portal. You can see the following types of
data that Cisco WLAN controllers collect for wireless clients on
the Devices and Device Details pages in the IoT Security portal.
Data
collected for IEEE 802.11 wireless clients (Wi-Fi clients):
- Access point with which the wireless client is currently associated and the length of its connection
- SSID through which the client is associated with the access point
- SNR (signal-to-noise ratio)
- RSSI (radio signal strength indicator)
- Radio band (2.4 GHz or 5 GHz)
- IEEE standard (802.11a/b/g/n/ac/ax)
- Encryption ciphers like CCMP-128 (AES) that the Cisco WLAN controller returns
- Authentication details (WPA2 PSK, WPA 802.1X, WPA, WEP, open)
Data
collected for Bluetooth clients and Bluetooth Low Energy (BLE) clients:
- IP address, MAC address, model, and name of the access point with which the Bluetooth or BLE client is currently associated
- MAC address of the Bluetooth or BLE device
- Bluetooth type (Bluetooth or BLE)
- Frequency (2.4 GHz)
- Channel
- Duration of the current connection
The
Device Details page only shows fields for which it has data. If
a Cisco WLAN controller provides partial data for a Wi-Fi, Bluetooth,
or BLE device, then IoT Security shows the data it received and
hides the fields for which it wasn't sent anything.
For
Cisco WLAN controllers to discover Bluetooth and BLE devices while checking
for wireless interference, CleanAir must be enabled on the controllers. (CleanAir
is a feature for detecting wireless interference and is available
in release 8.1 and later.) For Cisco WLAN controllers to receive
beacons from BLE devices, they must be running release 8.7 or later
and have scan mode enabled.
If IoT Security learns about a
device from both Cisco Prime and a controller, the latest data from
either one takes precedence and overrides previous values if different.
If
two controllers provide data about the same wireless client—perhaps because
it roamed between access points managed by different controllers—the most
recent data will be shown.
Integrating with Cisco WLAN controllers requires either a full-featured Cortex XSOAR server
or the purchase and activation of an IoT Security third-party integration add-on license, which comes with a free cohosted Cortex XSOAR instance. The basic
plan includes a license for three integration add-ons, one of which can be used for
this. The advanced plan includes a license for all supported third-party
integrations.
