Installing a QRadar Extension

The Extensions Management window in QRadar is used to add applications or content extensions to your deployment to improve the functionality of QRadar. Extensions can contain content, such as rules, reports, searches, reference sets, and dashboards. Extensions can also install applications that deliver specific new functionality to QRadar. The About tab outlines the contents of the extension that are being added to QRadar. Content extensions that are installed do not disrupt QRadar user activity and do not restart services.


  1. Log in to the QRadar Console as an administrator.
  2. Download the file to your laptop or workstation from the X-Force App Exchange:
  3. Click the Admin tab, then click Extensions Management in the System Configuration section.
  4. To upload an extension, click Add and select the extension to upload.
  5. Note: The extension (zip) must be downloaded to your local computer before it can be uploaded to the Console.

  6. To install the extension immediately, select the Install immediately check box and then click Add.
    A preview of the content is displayed before the extension is installed, and the content items are compared to content items that are already in the deployment. If the content items exist, you can choose to overwrite them or to keep the existing data. If you choose to keep the existing data, no updated content extension items are installed.
  7. Select Overwrite when prompted to add the new data to your QRadar appliance.
  8. The installation is complete and the status is displayed in QRadar.


If a yellow caution icon is displayed in the Status column there might be potential issues with the digital signature or installation. Hover over the icon for more information. Extensions that are unsigned or are signed by the developer, but not validated by your vendor, might cause compatibility issues in your deployment.

If you are installing an updated version of an extension, review the change list to determine if you need to update any rules. When the extension is applied to QRadar, administrator or user rules are not modified by QRadar; instead, the base enterprise template is updated. If a rule change includes a new building block update, performance change, or new rule tests, consider updating or recreating your existing rule from the rule template.
