This section describes how to configure retrieval of custom event properties from Kaspersky CyberTrace outgoing events, in addition to standard fields. As a result of this setting, the MD5, SHA1, and SHA256 hashes will be extracted and the extraction rule of the Source IP field will be redefined.

To configure retrieval of custom event properties:

  1. Select the Log Activity tab, and then click Add Filter.

    The Add Filter form opens.

  2. Fill in the form:
    1. In the Parameter drop-down list, select Log Source [Indexed].
    2. In the Operator drop-down list, select Equals.
    3. In the Log Source list, select KL_Threat_Feed_Service_v2.

      The selection KL_Threat_Feed_Service_v2 is the log source name that is set in the OutputSettings > EventFormat element and the OutputSettings > AlertFormat element of the Kaspersky CyberTrace Service configuration file (you can also set them by using Kaspersky CyberTrace Web).
