Data Forwarder Fields

Environment

  • Carbon Black Cloud Console: December 2019 Release (0.51.0 backend) and Higher
  • CB Cloud Data Forwarder: All Versions
  • Amazon Simple Storage Service (Amazon S3)

Objective

This document describes how the Carbon Black Cloud Forwarders map field types into the output JSON format.

Data Types

Basic data types such as “int” and “string” map directly to the corresponding JSON data types. Additional data types are described below:

  • Base64 - JSON string containing base64 encoded binary data.
  • Ipaddr - JSON string containing canonically formatted IPv4 or IPv6 address.
  • Datetime - JSON string containing ISO 8601 date/time format. If no time zone is included, UTC is assumed. All timestamps emitted by the Data Forwarder are sent in ISO 8601 format.
  • String enum - JSON string containing the stringified version of the enum from the relevant protobuf field, with the common prefix stripped off. For example, “BLOCK”.
  • String enum bitmask - Same as above, but for bitmask input fields, add OR " | " markers between each set bit. For example, for a CbFileAction of 0x300 would be “OPEN_READ | OPEN_WRITE”.

Event Fields

“Common fields” are present in all event types, while other fields are only present for a specific event type.

Legend:

  • FILTERABLE - Indicates whether the field is supported in the query for a filter
  • TOKENIZED - The field supports partial phrase matching through Tokenization
  • WILDCARD - The field supports wildcard characters

Common Fields

The Carbon Black Cloud Data Forwarder emits a set of common fields for every endpoint event. These fields represent common metadata for the organization, device, and process to which this event belongs.

Note: A new copy of the alert will be sent if something changes on the backend.
Field Definition Capabilities
action Specific endpoint action observed by sensor during this event. Enum values vary by event type FILTERABLE
backend_timestamp Time when the backend received the batch of events, based on Carbon Black Cloud backend’s clock as an RFC 3339 formatted time string based on UTC to the seconds; may differ from device_timestamp by a few minutes due to asynchronous processing

Example: 2021-07-28 18:43:51 +0000 UTC
device_group Sensor group to which the endpoint was assigned when the sensor recorded the event data FILTERABLE WILDCARD
device_id Integer ID of the device that created this event FILTERABLE
device_name Hostname of the device that created this event FILTERABLE WILDCARD

Example: 2021-07-28 18:43:51 +0000 UTC
event_origin Indicates which product the event came from.
“EDR” indicates the event originated from Enterprise EDR.
“NGAV” indicates the event originated from Endpoint Standard.
FILTERABLE
