IoT Security Solution Setup

Set up the multiple components that constitute the IoT Security solution.
The following is an overview of the main steps involved in setting up the IoT Security solution with particular focus on the following three components:
  • Next-generation firewalls with or without Panorama management
  • Logging service with or without a Cortex Data Lake instance
  • IoT Security app
The solution also makes use of the update server for device dictionary file updates and the Customer Support Portal and hub for IoT Security user management. Optionally, IoT Security integrates with Prisma Access and, through XSOAR, with third-party products.
Learn about the main steps involved in the IoT Security solution setup:

1 - Check Firewall Support and Prerequisites

Most current Palo Alto Networks firewall models support IoT Security with a few exceptions and with different degrees of functionality depending on the PAN-OS release:
  • PAN-OS 8.1, PAN-OS 9.0, and PAN-OS 9.1: Device visibility and manually configured Security policy enforcement
  • PAN-OS 10.0 or later: Device visibility and automated Security policy enforcement through Device-ID
Although IoT Security is a cloud app and is always running its latest software version, make sure the firewall models and PAN-OS versions on them support the level of functionality you want.
In addition, there are several prerequisites. For example, each firewall that integrates with IoT Security must have an IoT Security subscription. Not all firewalls on your network must subscribe to IoT Security; only those that collect network traffic and forward logs to it and those after PAN-OS 10.0 that receive policy recommendations and IP address-to-device mappings from it.

2 - Onboard IoT Security

IoT Security onboarding is a six-step process that starts from an
Activate
link in an email from Palo Alto Networks. (If you have an Enterprise License Agreement, it starts either in the Customer Support Portal or in the hub). During the IoT Security onboarding process, do the following depending on what you’re activating:
  • Create an IoT Security tenant
  • (
    IoT Security Subscription
    ) Activate a new Cortex Data Lake instance or associate an existing one with your IoT Security tenant
    or
    (
    IoT Security Subscription - Doesn’t Require Data Lake
    ) Specify the data ingestion region
  • Subscribe firewalls to IoT Security services
  • Optionally activate a third-party integrations add-on

3 - Prepare Firewalls

For IoT Security to discover network-connected devices and assess their network behavior patterns, it needs quality network metadata from next-generation firewalls. Therefore, it’s essential that firewalls are placed on the network and configured to collect metadata from traffic and forward it for IoT Security to access. In particular, DHCP traffic is important because it links dynamically assigned IP addresses to device MAC addresses, making them trackable over time.
Firewalls must also provide IoT Security with metadata for other types of traffic that devices generate. They do this by enforcing policy on network traffic, creating logs, and then forwarding them to the logging service, which then streams the metadata to IoT Security.

4 - Install Certificates and Licenses

Logging service and device licenses permit next-generation firewalls to connect to the logging service and IoT Security. Logging service and device certificates authenticate these connections. Firewalls need these licenses and certificates to integrate with IoT Security.
Firewalls running PAN-OS 8.1–10.0 use logging service certificates to secure communications with the logging service so they can forward various logs to it. From PAN-OS 10.0, when Device-ID was introduced, firewalls use device certificates to secure communications with IoT Security to get IP address-to-device mappings and recommended policy rules. (Note: Panorama-managed firewalls can get recommended policy rules either directly from IoT Security or indirectly from IoT Security through Panorama.) From PAN-OS 10.1, firewalls use just one device certificate to secure connections to both the logging service and IoT Security.

5 - Configure Logging

Configure Security policy rules on firewalls to log traffic and forward logs to the logging service where IoT Security accesses it. The more network traffic metadata IoT Security has for analysis, the more quickly and confidently it identifies devices and establishes a baseline of their normal network behaviors. This results in a broader application of Security policy rules based on Device-ID (IoT Security sends firewalls IP address-to-device mappings only when it has a high confidence in their identities) and broader and deeper insight into device risk and real and potential security threats.
