Enforcing scan configurations

The list of available patches comes from scanning the endpoints in your network. The scan configuration determines a scanning technique and frequency. A scan configuration is enforced by targeting computer groups.

The available scanning techniques include the offline CAB file (recommended), online Microsoft Windows Update, and Windows Server Update Services (WSUS) Scan.

Offline CAB file

The CAB file is stored locally by the Tanium Client and contains cumulative security and quality patches for all products in the Microsoft Update Catalog, including Windows and Office. On the Patch home page, the latest status of the offline CAB file is available. The active CAB file is the most recent, verified file published by Microsoft. Patch uses only the active CAB file for scan configurations. A rejected CAB is not pushed to a computer group.

Online to Microsoft Windows Update

This option creates additional network traffic between the Tanium Client and Microsoft and is for Windows operating system updates only. The full range of patches are available for the Windows operating system:

  • Critical patches
  • Cumulative security and quality patches
  • Non-security and optional updates

WSUS Scan

Using WSUS servers for patching activities gives the option for the full range of patch types for all products in the Microsoft Update Catalog, including Windows and Office. However, some additional configuration is required. The Tanium Client must be able to contact the WSUS server, and patches must be approved before they can be downloaded.

The guidelines about how many clients a WSUS server can support are similar to the Microsoft guidelines for SCCM: up to 150,000 clients per WSUS server. See Microsoft Docs: Size and scale numbers for System Center Configuration Manager.

Configure WSUS Scan

  1. Add the WSUS Server URL to the whitelist.
    1. From the Patch home page, go to Settings .
    2. In the WSUS Server Configuration section, enter the URL and click Submit.
    3. A regular expression for the URL is generated ad added to the whitelist. Click View Whitelisted URLs, or go to Administration > Whitelisted URLs to view the entry that was added.
  2. On the WSUS server, change the following settings:
    • Set the intranet URL for detecting updates and the statistics server to: http://<WSUS server URL>:<port>.
    • We recommend disabling the Configure Automatic Updates setting.

Create a scan configuration

You can create multiple scan configurations and add computer group enforcements as needed.

  1. In the Patch menu, click Scan Management.
  2. Click Create Configuration and provide a name.
  3. Choose the configuration options.
    1. Select a Configuration Technique.
      If you choose Offline CAB File, you can select Scan after new CAB file is downloaded to ensure that the endpoints are scanned whenever a new CAB file is published. Selecting this setting overrides the frequency settings when a new CAB file is detected.
    2. In the Frequency field, enter a number and a time parameter.

      We recommend scanning once a day or longer between scans.

    3. (Optional) Enable Random Scan Delay and enter a time to distribute the network activity.

      The default is 120 minutes.

      For VDI environments, we recommend a longer delay to reduce the impact of the scan on the host system.

  4. Click Save.
  5. On the scan configuration details page, add one or more computer groups.
    1. Click Add Computer Group.

      Enabling the patch applicability results provides a refined aggregation for the specific computer group.

    2. Click Add and provide your credentials. Click Confirm.

The list of available patches might be displayed within 15-30 minutes. Longer scan delays might result in patches appearing slowly. If no data appears after the scan delay, contact your TAM. If an endpoint cannot be scanned, for example if it is offline, it is scanned at the earliest opportunity.

View enforcement status

By reviewing a scan configuration, you can see which endpoints in the computer group contain the enforced configuration.

  1. In the Patch menu, click Scan Management.
  2. On the Scan Configurations tab, select a configuration.
  3. Expand the computer group to see more details about the scan status.
  4. Click Interact to open the question results for each endpoint.

    The Interact results grid shows the endpoint status and the reason, if it is not enforced.

Prioritize scan configurations

You can create multiple scan configurations with multiple computer groups. The order of the configuration decides its priority. If an endpoint is in multiple computer groups with conflicting configurations, only the highest priority configuration is applied to the endpoint.

  1. In the Patch menu, click Scan Management.
  2. On the Scan Configurations tab, click Prioritize.
  3. Move the Scan Configurations by dragging and dropping or entering a number into the Conflict Resolution Order field and pressing Enter.
  4. Click Save.

Remove a scan enforcement

Removing a computer group from a scan configuration removes the enforcement.

  1. In the Patch menu, click Scan Management.
  2. On the Scan Configurations tab, select a configuration.
  3. Delete the computer group.

Delete a scan configuration

After the enforcements are removed, you can delete a scan configuration.

  1. In the Patch menu, click Scan Management.
  2. On the Scan Configurations tab, select a configuration.
  3. If the scan configuration is enforced against Computer Groups, remove all groups.
  4. In the upper right, click Delete.
  5. Confirm the deletion.
