Creating event Enrichment rules

To create event enrichment rules:

  1. In the KUMA web interface, open the ResourcesEnrichment rules section and in the left part of the window, select or create a folder for the new rule.

    The list of available enrichment rules will be displayed.

  2. Click Add enrichment rule to create a new rule.

    The enrichment rule window will be displayed.

  3. Enter the rule configuration parameters:
    1. In the Name field, enter a unique name for the rule. The name must contain 1 to 128 Unicode characters.
    2. In the Tenant drop-down list, select the tenant that will own this resource.
    3. In the Source kind drop-down list, select cybertrace-http.
    4. Specify the URL of the CyberTrace server to which you want to connect. For example, example.domain.com:9999.
    5. If necessary, use the Number of connections field to specify the maximum number of connections to the CyberTrace server that can be simultaneously established by KUMA. By default, this value is equal to the number of vCPUs of the KUMA Core server.
    6. In the RPS field, enter the number of requests to the CyberTrace server per second that KUMA can make. The default value is 1000.
    7. In the Timeout field, specify the maximum number of seconds KUMA should wait for a response from the CyberTrace server. Until a response is received or the time expires, the event is not sent to the Correlator. If a response is received before the timeout, it is added to the TI field of the event and the event processing continues. The default value is 30.
    8. In the Mapping settings block, you must specify the fields of events to be checked via CyberTrace, and define the rules for mapping fields of KUMA events to CyberTrace indicator types:
      • In the KUMA field column, select the field whose value must be sent to CyberTrace.
      • In the CyberTrace indicator column, select the CyberTrace indicator type for every field you selected:
        • ip
        • url
        • hash

      You must provide at least one string to the table. You can use the Add row button to add a string, and can use the cross button to remove a string.

    9. Use the Debug toggle switch to indicate whether or not to enable logging of service operations. Logging is disabled by default.
    10. If necessary, in the Description field, add up to 4,000 Unicode characters describing the resource.
    11. In the Filter section, you can specify conditions to identify events that will be processed using the enrichment rule. You can select an existing filter from the drop-down list or create a new filter.

  4. Click Save.

A new enrichment rule will be created.

CyberTrace indicator search integration is now configured. You can now add the created enrichment rule to a collector. You must restart KUMA collectors to apply the new settings.

If any of the CyberTrace fields in the events details area contains "[{" or "}]" values, it means that information from CyberTrace data feed was processed incorrectly and it's possible that some of the data is not displayed. You can get all data feed information by copying the events TI indicator field value from KUMA and searching for it in the CyberTrace in the indicators section. All relevant information will be displayed in the Indicator context section of CyberTrace.
