Before you begin
This extension is intended to add rules for fresh appliance installations of QRadar 7.2.6. Administrators who have upgraded from QRadar 7.2.5 already have this anomaly content included in QRadar by default. Administrators who upgraded and still want to install this extension can do so, however, the administrator will receive overwrite value notices for these rules and building blocks when they install the extension.

Installing a QRadar Extension
The Extension Management window in QRadar is used to add applications to your deployment to improve the functionality or add customize content to QRadar. Extensions can contain content, such as rules, reports, searches, reference sets, and dashboards or extensions can install applications that deliver specific new functionality to QRadar. The About tab of this article will outline the contents of the extension being added to QRadar.
Procedure
- Download the Anomaly extension from the IBM X-Force App Exchange: https://exchange.xforce.ibmcloud.com/hub/extension/IBMQRadar:IBMContentPackageInternalAnomaly
- Log in to the QRadar Console as an administrator.
- Click the Admin tab.
- Click the Extension Management icon.
- To upload an extension, click Add and select the extension to upload.
Note: The extension (zip) must be downloaded to your local computer before it can be uploaded to the Console appliance.
- To install the extension immediately, select the Install immediately check box and then click Add.
A preview of the application content is displayed. You can choose how existing content items are handled.
- To preview the contents of an extension after it is added and before it is installed, select it from the list of extensions, and click More Details.
Before the extension is installed, 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.
Results
After the extension is added, a yellow caution icon in the Status column indicates potential issues with the digital signature. Hover the mouse over the triangle 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, administrators should review the change list to determine if they 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, then administrators should consider updating or recreating their existing rule from the rule template.
