Article Summary

To open the Enrichment Settings:

  1. From the top right corner of any page, click image.png. The System Settings page opens.
  2. In the Categories/Subcategories pane of the System Settings page, select Enrichment.

Configuring Data Enrichment Settings

  • Fetch software vulnerabilities from NVD DB (required, default: true) - Select this option to fetch software vulnerabilities details from the NIST National Vulnerabilities Database (NVD) using Axonius Static Analysis.
  • Enrich software vulnerabilities from NVD DB (required, default: true) - Select this option to enrich software vulnerabilities with additional information from the NIST National Vulnerabilities Database (NVD).
    Note:

    If this option is cleared, software vulnerabilities details from NVD are only enriched using Axonius Static Analysis.

  • Enrich software vulnerabilities from CISA DB (required, default: true) - Select this option to enrich software vulnerabilities details from the CISA Known Exploited Vulnerabilities Catalog via connected adapters.
  • Enrich software vulnerabilities from EPSS DB (required, default: true) - Select this option to enrich software vulnerabilities details from the Exploit Prediction Scoring System via connected adapters.
  • Enrich software vulnerabilities from MSRC DB (required, default: true) - Select this option to enrich software vulnerabilities details from MSRC via connected adapters.
Note:

When all of the above options are cleared, all enrichments are cleaned from devices in the next discovery cycle.

  • Fetch software vulnerabilities even when the vendor name is unknown

    • Select this option to have Axonius fetch vulnerabilities even if the software vendor name is unknown.
    • Clear this option to have Axonius fetch vulnerabilities only if they include both software and vendor names.
  • Enable CVE enrichment proxy settings (required, default: switched off) - Set a proxy to download the CVE database used for CVE enrichment.

    • Toggle on to enable CVE enrichment proxy settings.
    • You can set a Proxy address and Proxy port. The default port value is 8080.
      When this is set, the proxy configured here is used, otherwise the proxy configured in Settings → Access Management → Proxy → Proxy Settings is used. When no proxy is configured in either of these settings, then a proxy is not used.
  • Don’t create new users from WMI devices - Select this option so that the data enrichment process does not create new users from devices fetched by the WMI adapter.

  • Prioritize Top Console User for last used users association - Axonius runs an ongoing process that associates devices with users. It does so by looking at various device fields that come from adapters and determines if they might indicate the ownership of a particular user of that device.

    • Select this option to prioritize the value coming from 'Top Console User' for the association.
    • Clear this option to use all available fields and prioritize by the last seen date.
  • Enable device location mapping (required, default: switched off) - Toggle on to upload a CSV file that maps between subnets and locations. Note that device location mapping only enriches devices fetched from the time it is loaded, and not devices already existing in the system. You wil be able to see the device location mapping in the 'Network Interfaces' complex field in each device to which it was added.

    • In Device location mapping CSV file, select a CSV file that meets the following requirements, and then click Upload File to upload it.
      • The CSV file must be encoded in UTF-8.
      • The CSV file must include two columns and headers: (case-insensitive):
        • Subnet, must be in CIDR notation.
        • Either of the following:
          • Location
          • Location Name
      • The CSV file supports additional optional columns and headers (case- sensitive):
        • Location ID
        • Facility Name
        • Facility ID
        • Region
        • Zone
        • Country
        • State
        • City
        • Postal Code
        • Street Address
        • Full Address
        • Latitude
        • Longitude
        • AD SiteName
        • AD SiteCode
        • Site Criticality
        • Site Function
        • Comments
Note:
  • If the file contains the same subnet more than once, with different values for the other fields, the last match (that is, the value in the latest row) is used.
  • If a file contains Subnet values that overlap each other when one set has more detailed information, devices are enriched with all the information in the files.
  • MAC address metadata enrichment (DeepMac) - Toggle on to enrich each MAC address with data from the DeepMac database, which adds the Production Date, Manufacturing Country, and Device Type.

Configuring Custom Enrichment Settings

CustomEnrichment4

Use Custom Enrichment to enrich asset data received from adapters, and add columns containing additional useful information. This allows you to add a large number of custom or proprietary fields.

It is recommended to use the Manage Custom Enrichment - Enrich assets with CSV file enforcement action, as opposed to configuring Custom Enrichment from the System Settings, as it has the following benefits:

  • It adds powerful scheduling and customization capabilities to Custom Enrichment.
  • It enables you to select adapter fields for the statement using the Syntax Helper and to automatically validate the statement syntax.

Creating the Custom Enrichment

This section describes how to create the Custom Enrichment from System Settings.

Before doing so, create the following:

To create a Custom Enrichment from System Settings:

  1. From the top right corner of any page, click image.png. The System Settings page opens.

  2. In the Categories/Subcategories pane of the System Settings page, select Enrichment.

  3. In the Custom Enrichment section on the Enrichment page, toggle on Enable custom enrichment to activate Custom Enrichment.

CustomEnrichment

  1. Copy the statement, which you wrote, to the Enrichment statement field.

  2. Choose the location of the CSV file. You can either upload a file from your system, or use a file saved in a storage system.

    • To upload a file from your system:

      1. From the Select file input method dropdown, choose Upload file.
      2. Click Upload File to browse for and upload the CSV file.
    • To use a file from an online storage location:

      Note:

      If you are uploading a file from an online storage location and you want to use this file only for custom enrichment, you must disable the Active connection setting on the CSV adapter connection. In this case, the CSV adapter connection will not fetch new assets.

      • Axonius uses the capabilities of the CSV adapter to use a CSV file from a storage location.
      • Prerequisite: Make sure you have configured the relevant CSV file using a CSV adapter connection. Give a name to the connection (connection label) so that you can identify it in the dropdown list.
      1. Configure the file name, location, and credentials required to access the file using the CSV adapter. These can be SMB, Azure, blob, Amazon S3 bucket, and more.
      2. From the Select file input method dropdown, choose Select CSV adapter connection.

FileInputMethod

3. From the Select adapter connection dropdown, select the connection that contains the file to be used.
CSVFiulesdropdown

  1. Do one of the following:
    • Select + to add another Custom Enrichment. You can add more than one Custom Enrichment. They run sequentially and are dependent on each other, meaning that one Custom Enrichment can use the results of a previous one. It is possible to reorder the sequence of the Custom Enrichments.
    • Select Save at the bottom of the page. The system validates the statement and the CSV file.

The Custom Enrichment runs the first time you create it after you click Save, and then every 60 minutes. If you make changes to the Custom Enrichment, it runs again immediately. If the enrichment CSV file was updated but the enrichment statement was not changed, the enrichment does not run immediately but runs during the next hourly cycle. It also runs in the post-correlation phase of each global discovery cycle.

Removing a Custom Enrichment

When you remove an enrichment, all the information it added is removed.

This section describes how to remove a Custom Enrichment from System Settings.

To remove a Custom Enrichment

  1. In the Custom Enrichment section, click the small x to the right of the Enrichment you want to remove.

Refer to Custom Enrichment to learn more about how to work with this feature.

Association

Association settings relate to user-device association in Axonius

  • Users to be associated with devices that share a mutual domain (if domain exists on the device) - Select this option to associate only users and devices that share the same domain.
  • Avoid association if device doesn't have a domain - Select this option to set the Association process to skip devices that don’t have a value populated in their Domain field.
  • Filter users from Last Used Users (comma separated) - Enter a list of users to remove from the 'Last Used Users' list.
