    Set up IoT Security and XSOAR for Aruba Central Integration

    Set up IoT Security and Cortex XSOAR to integrate with Aruba Central.
    You must also configure Cortex XSOAR with an Aruba Central integration instance and a job to import device data from the Aruba Central server. You can set the job to run at regular intervals or on demand. The configuration requires the following information from the Aruba Central:
    • Domain URL for a cloud-hosted Aruba Central instance, or an FQDN for an on-premises Aruba Central server
    • Username and password of the read/write user account that XSOAR uses when logging in to the Aruba Central API and obtaining a Cross-Site Request Forgery (CSRF) token. This is the first of three steps to generate an access token and is part of the Open Authorization 2.0 (OAuth2) mechanism.
    • Customer ID, which is used with the CSRF token to get an authorization code. This is the second step.
    • Client ID and client secret, which in combination with the authorization code, XSOAR uses to acquire an access token. This is the third and final step.
    To set up IoT Security to integrate through a cloud-hosted Cortex XSOAR instance with an on-premises Aruba Central server, you must also add a Cortex XSOAR engine to your network.

    Cortex XSOAR Engine Installation

    An on-premises XSOAR engine facilitates communications between the Cortex XSOAR cloud and Aruba Central server. Although it's possible to install an XSOAR engine on machines running Windows, macOS, and Linux operating systems, only an engine on a Linux machine supports IoT Security integrations. For more information about operating system and hardware requirements, see the Cortex Administrator’s Guide.
    We recommend downloading the XSOAR engine using the shell installer script and installing it on a Linux machine. This simplifies the deployment by automatically installing all required dependencies and also enables remote engine upgrades.
    When placing the XSOAR engine on your network, make sure it can form SSH connections to your Aruba Central server. By default, SSH uses TCP port 22.
    Also make sure that the perimeter firewall allows the XSOAR engine to form HTTPS connections on TCP port 443 to the Cortex cloud at https://<your-domain>.iot.demisto.live/. You can see the URL of your XSOAR instance when you log in to the IoT Security portal and click
    Integrations
    Launch Cortex XSOAR
    . It’s visible in the address bar of the web page displaying the XSOAR interface.
    To create an XSOAR engine, access the Cortex XSOAR interface (from the IoT Security portal, click
    Integrations
    Launch Cortex XSOAR
    ). Click
    Settings
    Engines

    Configure IoT Security and Cortex XSOAR

    1. Log in to IoT Security and from there access Aruba Central settings in Cortex XSOAR.
      1. Log in to IoT Security and then click
        Integrations
        .
      2. IoT Security uses Cortex XSOAR to integrate with Aruba Central, and the settings you must configure to integrate with it are in the XSOAR interface. To access these settings, click
        Launch Cortex XSOAR
        .
        The Cortex XSOAR interface opens in a new browser window.
      3. Click
        Settings
         in the left navigation menu, search for
        aruba central
        to locate it among other instances.
    2. Configure the Aruba Central integration instance.
      1. Click
        Add instance
         to open the settings panel.
      2. Enter the following settings:
        Name
        : Use the default name of the instance or enter a new one.
        Remember the instance name because you are going to use it again when creating a job that Cortex XSOAR will run to gather device data from the Aruba Central instance specified in this integration instance.
        Domain URL
        : Enter the domain URL of a cloud-hosted Aruba Central instance or the FQDN of an on-premises Aruba Central server.
        Customer ID
        : Copy and paste the customer ID that you copied from the Aruba Central UI and pasted and saved in a text file.
        Client ID
        : Copy and paste the client ID that you copied and saved from the Aruba Central UI.
        Client Secret
        : Copy and paste the customer ID that you copied and saved from the Aruba Central UI.
        Username
        : Type the name of the read-only user account that you previously created for the XSOAR engine to use when connecting to the Aruba Central API.
        Password
        : Type the password associated with the user account.
        Use single engine
        : When using a cloud-based XSOAR instance and an on-premises Aruba Central server, choose the XSOAR engine that you want to communicate with the Aruba Central server.
      3. When finished, click
        Test
        .
        If the test is successful, a Success message appears. If not, check that the settings were entered correctly and then test the configuration again.
      4. After the test succeeds, click
        Done
         to save your changes, close the settings panel, and activate the instance.
    3. Create a job for XSOAR to query Aruba Central for device details and import them to IoT Security.
      IoT Security updates devices that are in its database and whose MAC address matches that returned by Aruba Central. If Aruba Central returns device information for a MAC address that’s not in the IoT Security database, then IoT Security creates a new entry and adds the imported MAC address to its database along with any associated device information about it.
      1. Copy the name of the instance you just created, click
        Jobs
         near the bottom of the left navigation menu and then click
        New Job
         at the top of the page.
      2. In the New Job panel that appears, enter the following and leave the other settings at their default values:
        Recurring
        : Select this if you want to periodically import device information from Aruba Central. Clear it if you want to import data on demand.
        Every
        : If you select
        Recurring
        , enter a number and set the interval value (Minutes, Hours, Days, or Weeks) and select the days on which to run the job. (If you don’t select specific days, then the job will run everyday by default.) This determines how often XSOAR queries Aruba Central for information about its devices. For example, every day at 2:00 AM.
        Name
        : Enter a name for the job.
        Playbook
        : Choose
        Import Aruba Central Device Data
        .
        Import Aruba Central wired client details to IoT Security
        : Select to import device information for both wired and wireless devices. Clear to import device information for wireless devices only.
        Integration Instance Name
        : Paste the instance name you copied a few moments ago.
      3. Click
        Create new job
        .
        The job appears in the Jobs list.
    4. Enable the job and run it.
      1. Check the Job Status for the job you created. If it’s Disabled, select its check box and then click
        Enable
        .
      2. After you enable it, keep the check box selected and click
        Run now
        . The Run Status changes from Idle to Running.
        If you selected
        Recurring
        , XSOAR queries Aruba Central for device information at the defined interval and forwards imported information to IoT Security.
        If you cleared
        Recurring
        , XSOAR immediately queries Aruba Central and forwards imported device information to IoT Security.
    5. If you created more integration instances for multiple on-premises Aruba Central servers, add more jobs as necessary.
      Each Aruba Central server requires a separate job.
      Run the job for each integration instance you create. The first time you run a job that references an integration instance, it triggers XSOAR to report the instance to IoT Security, which then displays the integration instance on the Integrations page.
    6. When done, return to the IoT Security portal and check the status of the Aruba Central integration.
      An integration instance can be in one of the following four states, which IoT Security displays in the Status column on the Integrations page:
      • Disabled
         means that either the integration was configured but intentionally disabled or it was never configured and a job that references it is enabled and running.
      • Error
         means that the integration was configured and enabled but is not functioning properly, possibly due to a configuration error or network condition.
      • Inactive
         means that the integration was configured and enabled but no job has run for at least the past 60 minutes.
      • Active
         means that the integration was configured and enabled and is functioning properly.
      When you see that its status is
      Active
      , the setup is complete.
