Put a Device in Quarantine Using Cisco ISE pxGrid
Use the IoT Security integration with Cisco ISE pxGrid
to quarantine IoT devices of concern.
As an IoT Security user, you can selectively
quarantine devices through Cisco ISE pxGrid. In short, ISE quarantines
impacted devices by applying a policy that IoT Security generates
in one of its exception rules.
Let’s say you want to quarantine
a device because you saw an alert that concerns you. In the IoT
Security portal, use the Quarantine via Cisco pxGrid option.
IoT Security sends a quarantine command through Cortex XSOAR, the
XSOAR engine, and pxGrid to ISE.
In response, ISE sends a
Disconnect-Request message to the switch through which the impacted
device accesses the network and disconnects it. When the device
reconnects, ISE checks the quarantine policy it received from IoT
Security, finds that it applies to the device requesting access,
and assigns it to a quarantine VLAN. The device remains in quarantine
while you investigate the cause of the alert. Once it’s resolved,
you can then use the Release via Cisco pxGrid option to return the device
to its regularly assigned VLAN.
For information about
creating an authorization profile and exception authorization policy
that assigns a quarantined device to a specific VLAN, see the “Setup Adaptive Network Control”
chapter in the Cisco Identity Services Engine Administration Guide,
Release 2.2.

- Click Send.IoT Security automatically creates a policy called panw_iot_quarantine_anc_policy, assigns it to the device, and sends it through Cisco pxGrid to ISE. The policy appears in the ISE UI at .

After you click Send, a link appears in the IoT Security portal. When you click it, a new browser window opens to the XSOAR playbook for this action.![]()
To confirm that the task was completed, click the link to the XSOAR playbook for this action.For the link in IoT Security to open the corresponding playbook in Cortex XSOAR, you must already be logged in to your XSOAR instance before clicking it.The green boxes in the playbook indicate that a particular step was successfully performed. Following the path through the playbook gives you feedback about whether an action was carried out successfully or, if not, where the process changed course.
