Integrate IoT Security with Cisco ISE pxGrid
Integrate IoT Security through pxGrid with Cisco ISE
to provide network access control (NAC) to IoT devices.
IoT Security is an IoT (Internet of Things)
security solution that uses deep machine learning to discover and
categorize every IoT device on your network. It creates a baseline
of normal behavior for each individual IoT device, continuously
monitors for anomalous behavior, and then alerts administrators
whenever it finds such anomalies.
Cisco pxGrid (Platform Exchange
Grid) is a platform that enables various network security products
to share information so they can discover and respond to threats
quickly. A pxGrid controller coordinates connections among partner
nodes and runs on Cisco ISE (Identity Services Engine), a product
for creating and enforcing network access and security policies.
The pxGrid controller provides a means for partners to publish services
to ISE and other connected nodes and subscribe to services from
them.
You can integrate IoT Security through Cortex XSOAR
and pxGrid with Cisco ISE. By integrating these solutions, you can
respond to security alerts by quarantining IoT devices to mitigate
risk and later removing them from quarantine after the threat subsides.
Ensure
the XSOAR engine can form an HTTPS connection to your Cisco pxGrid controller/ISE
instance on TCP port 8910. The engine uses this port when authenticating
with pxGrid and when sending it IoT device data and quarantine commands. In
addition, ensure that the XSOAR engine can form an HTTP connection
on TCP port 443 with Cortex XSOAR.
In a distributed environment,
multiple firewalls report metadata to the IoT Security Cloud, which
then sends it through Cortex XSOAR to the XSOAR engine designated
to communicate through pxGrid to the ISE admin node.
Integrating with Cisco ISE pxGrid 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.
