Quarantine a Device Using Cisco ISE
Use the IoT Security integration with Cisco ISE to quarantine IoT devices of concern.

One of the following Cortex XSOAR setups:

Through the IoT Security integration with Cisco ISE, you can send a request
to Cisco ISE to quarantine devices or to remove devices from quarantine.
Put a Device in Quarantine Using Cisco ISE
If you want to quarantine a device because you saw an alert that concerns you,
use the quarantine option on the
page. You can also do this in the Action menu in the Risks and
Alerts sections on the Device Details page.
- Select an alert on in the IoT Security portal.Click .

Click Send.IoT Security sends PanwIoTAlertSeverity and PanwIoTAlertType attributes, together with the MAC address of the impacted device, through Cortex XSOAR to all configured Cisco ISE instances. The instance or instances that have an endpoint with a matching MAC address apply the quarantine. The next time the device disconnects from the network and then reconnects, it requests access permission from Cisco ISE. If you configured an exception rule to put devices with a security alert into the quarantine VLAN, Cisco ISE will assign the device to that VLAN instead of its usual VLAN. While it’s in the quarantine VLAN, which has no connection to the rest of the network, you can investigate the alert. When it’s resolved, you can then release a device from quarantine.After you click Send, a link appears. When you click it, a new browser window opens to the XSOAR playbook for this action.![]()
To confirm that the quarantine command was sent, 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.Release a Device from Quarantine Using Cisco ISE
Remove devices from quarantine through the IoT Security integration with Cisco ISE.Removing a device from quarantine is the same procedure as putting it in quarantine except that you select on the page. This option is also available in the Action menu in the Risks and Alerts sections on the Device Details page.![]()
IoT Security sends ISE the PanwIoTAlertSeverity and PanwIoTAlertType attributes with None as the text string and the MAC address of the impacted device, which means the exception rule assigning it to a quarantine VLAN no longer applies to it. The instance or instances that have an endpoint with a matching MAC address release it from quarantine. The next time the device disconnects from the network and then reconnects, it requests network access from Cisco ISE. When ISE doesn’t find any matching exception rules in its policy and accepts the device back onto the network, it puts the device back in its normally assigned VLAN.
