Metadata

The Metadata object describes the metadata associated with the event. Defined by D3FEND d3f:Metadata.

Attributes

Caption	Name	Type	Description
Correlation UID	`correlation_uid`	String	The unique identifier used to correlate events.
Data Classification	`data_classification`	Data Classification[]	The Data Classification object includes information about data classification levels and data category types.
Event Code	`event_code`	String	The Event ID or Code that the product uses to describe the event.
Schema Extension	`extension`	Schema Extension[]	The schema extension used to create the event. 🚧 WARNING: DEPRECATED Schema Extension has been deprecated since 1.1.0. Use the `extensions` attribute instead.
Schema Extensions	`extensions`	Schema Extension[]	The schema extensions used to create the event.
Labels	`labels`	String[]	The list of category labels attached to the event or specific attributes. Labels are user defined tags or aliases added at normalization time. For example: `["network", "connection.ip:destination", "device.ip:source"]`
Log Level	`log_level`	String	The audit level at which an event was generated.
Log Name	`log_name`	String	The event log name. For example, syslog file name or Windows logging subsystem: Security.
Log Provider	`log_provider`	String	The logging provider or logging service that logged the event. For example, Microsoft-Windows-Security-Auditing.
Log Version	`log_version`	String	The event log schema version that specifies the format of the original event. For example syslog version or Cisco Log Schema Version.
Logged Time	`logged_time`	Timestamp	The time when the logging system collected and logged the event. This attribute is distinct from the event time in that event time typically contain the time extracted from the original event. Most of the time, these two times will be different.
Loggers	`loggers`	Logger[]	An array of Logger objects that describe the devices and logging products between the event source and its eventual destination. Note, this attribute can be used when there is a complex end-to-end path of event flow.
Modified Time	`modified_time`	Timestamp	The time when the event was last modified or enriched.
Original Time	`original_time`	String	The original event time as reported by the event source. For example, the time in the original format from system event log such as Syslog on Unix/Linux and the System event file on Windows. Omit if event is generated instead of collected via logs.
Processed Time	`processed_time`	Timestamp	The event processed time, such as an ETL operation.
Product	`product`	Product[]	The product that reported the event.
Profiles	`profiles`	String[]	The list of profiles used to create the event. Profiles should be referenced by their `name` attribute for core profiles, or `extension/name` for profiles from extensions.
Raw Data	`raw_data`	JSON	The event data as received from the event source.
Record ID	`record_id`	String	Unique identifier for the object
Sequence Number	`sequence`	Integer	Sequence number of the event. The sequence number is a value available in some events, to make the exact ordering of events unambiguous, regardless of the event time precision.
Tenant UID	`tenant_uid`	String	The unique tenant identifier.
Event UID	`uid`	String	The logging system-assigned unique identifier of an event instance.
Unmapped Data	`unmapped`	Unmapped[]	The attributes that are not mapped to the event schema. The names and values of those attributes are specific to the event source.
Version	`version`	String	The version of the OCSF schema, using Semantic Versioning Specification (SemVer). For example: 1.0.0. Event consumers use the version to determine the available event attributes.
