Cortex XDR Connector

The following is not supported in Tenable FedRAMP Moderate environments. For more information, see the Tenable FedRAMP Product Offering.

Cortex XDR is a detection and response app that natively integrates network, endpoint, and cloud data to stop sophisticated attacks. It accurately detects threats with behavioral analytics and reveals the root cause to speed up investigations.

Prerequisites and User Permissions

Before you begin configuring the connector, make sure you have the following:

• Cortex XDR Pro per Endpoint license is needed to run the integration.

• Generate Cortex XDR Credentials (API Key, API Key ID, and FQDN)

Generate Cortex XDR Credentials

Follow the instructions at Get Started with Cortex XDR APIs for the following:

1. Get your Cortex XDR API Key

2. Get your Cortex XDR API Key ID

3. Get your FQDN

Add a Connector

To add a new connector:

1. In the left navigation menu, click Connectors.

   The Connectors page appears.

   

2. In the upper-right corner, click Add new connector.

   The Connector Library appears.

   

3. In the search box, type the name of the connector.

4. On the tile for the connector, click Connect.

   The connector configuration options appear.

Configure the Connector

To configure the connector:

5. (Optional) In the Connector's Name text box, type a descriptive name for the connector.

6. Enter the credentials you generated earlier (FQDN, API Key, and API ID).

7. Data pulling configuration: This configuration has dynamic settings tailored to the specific connector and integration type. Below are the configurations relevant to this connector.

   • In the Asset Retention text box, type the number of days after which you want assets to be removed from Tenable Exposure Management. If an asset has not been detected or updated within the specified number of days, it is automatically removed from the application, ensuring your asset inventory is current and relevant.

     Tip: For more information, see Asset Retention.

   • For the Immediately remove assets when their status is option, choose to automatically remove assets that reach a certain asset status, for example, LOST.

8. Click the Test Connectivity button to verify that VTenable Exposure Management can connect to your Cortex XDR instance.
   

   • In the Test connectivity section, click the Test Connectivity button to verify that Tenable Exposure Management can connect to your connector instance.
     

     • A successful connectivity test confirms that the platform can connect to the connector instance. It does not, however, guarantee that the synchronization process will succeed, as additional syncing or processing issues may arise.
       

     • If the connectivity test fails, an error message with details about the issue appears. Click Show tests for more information about the exact error.
       

       

9. In the Connector scheduling section, configure the time and day(s) on which you want connector syncs to occur.

   Tip: For more information, see Connector Scheduling

10. Click Create. Tenable Exposure Management begins syncing the connector. The sync can take some time to complete.
    
    

11. To confirm the sync is complete, do the following:

    • Navigate to the Connectors page and monitor the connector's status. Sync is complete once the connector status is Connected.

    • View the sync logs for the connector to monitor the logs for a successful connection.

Locate Connector Assets in Tenable Exposure Management

As the connector discovers assets, Tenable Exposure Management ingests those devices for reporting.

To view assets by connector:

1. In Tenable Exposure Management, navigate to the Assets page.

2. In the Filters section, under 3rd Party Connectors, click the connector name for which you want to view assets.

   

   The asset list updates to show only assets from the selected connector.

Locate Connector Weaknesses in Tenable Exposure Management

As the connector discovers weaknesses, Tenable Exposure Management ingests those weaknesses for reporting.

To view weaknesses by connector: 

1. In Tenable Exposure Management, navigate to the Weaknesses page.

2. In the Filters section, under 3rd Party Connectors, click the connector name for which you want to view weaknesses.

   

   The weaknesses list updates to show only weaknesses from the selected connector.

3. Click on any weakness to view Weakness Details.

Locate Connector Findings in Tenable Exposure Management

As the connector discovers individual findings, Tenable Exposure Management ingests those findings for reporting.

To view findings by connector:

1. In Tenable Exposure Management, navigate to the Findings page.

2. In the Filters section, under 3rd Party Connectors, click the connector name for which you want to view findings

   

   The findings list updates to show only assets from the selected connector.

3. Click on any asset to view Finding Details.
