UDM field list

This document provides a list of fields available in the Unified Data Model(UDM) schema.

Field name and field type values can look similar. This document uses styleconventions to help you identify the differences:

Field type values use camelCase characters; for example,platform andeventType.
Field name values use lowercase characters; for example,platform andevent_type. When a field name consists of more than one word, an underscore is used to separate the words.
Standard data type values use lowercase characters.

For details about dashboard query examples, seeUDM Events andEntity Graph.

UDM field name formats

When specifying a field, use the following format:

<prefix>.<field_name1>.<field_name2>.<...>.<field_nameN>=<value>

Field name format for Detect Engine

When writing rules for Detect Engine:

Use the <prefix> pattern$event for Event fields; for example:
- $event.metadata.event_type
- $event.network.dhcp.opcode
- $event.principal.user.location.city
Use the <prefix> pattern$entity for Entity fields; for example:
- $entity.graph.entity.hostname
- $entity.graph.metadata.product_name

Field name format for parsers

When writing configuration-based normalizer (CBN) parsers:

Use the <prefix> patternevent.idm.read_only_udm for UDM Event fields; for example:
- event.idm.read_only_udm.metadata.event_type
- event.idm.read_only_udm.network.dhcp.opcode
- event.idm.read_only_udm.principal.user.location.city
Use the <prefix> patternevent.idm.entity for UDM Entity fields; for example:
- event.idm.entity.entity.user.user_display_name
- event.idm.entity.entity.asset.hostname

UDM Entity data model

TheUDM Entity Data model represents a state-in-time view of the objects within an enterprise, such as users, assets, and organizational resources. Unlike the Event Model, which captures point-in-time activities (telemetry), the Entity model provides the context necessary for effective threat hunting and risk scoring.

By mapping metadata from disparate sources like Active Directory, EDR inventories, and CMDBs into a unified structure, developers can programmatically correlate "who" or "what" is involved in a security incident. This model is essential for building relationship graphs, tracking asset criticality, and applying identity-centric security policies across the organization.

Entity

An Entity provides additional context about an item in a UDM event. Forexample, a PROCESS_LAUNCH event describes that user 'abc@example.corp'launched process 'shady.exe'.The event does not include information that user 'abc@example.com' is arecently terminated employee who administers a server storing finance data.Information stored in one or more Entities can add this additional context.

UDM Event data model

Field Name	Type	Label	Description
metadata	Metadata		Event metadata such as timestamp, source product, etc.
additional	google.protobuf.Struct		Any important vendor-specific event data that cannot be adequatelyrepresented within the formal sections of the UDM model.
principal	Noun		Represents the source of activity in the event. The principal is determined based on the context of the event being analyzed. For example, consider a scenario where a user on a host`xyz` makes an SSH connection to a remote host`1234`. The remote host then initiates a request to google.com. In the SSH connection event, the principal is`xyz`. In the request event to`google.com`, the principal is`1234`. The principal must include at least one machine-related (such as hostname, MAC addresses, IP addresses, port, product-specific identifiers like an Endpoint Detection and Response (EDR) asset ID) or user-related detail (for example, username). It can also include process details but must not include a domain name or any of the following fields: email, files, registry keys, or values.
src	Noun		Represents a source entity being acted upon by the participant along withthe device or process context for the source object (the machine where thesource object resides). For example, if user U copies file A on machine Xto file B on machine Y, both file A and machine X would be specified in thesrc portion of the UDM event.
target	Noun		Represents a target entity being referenced by the event or an object onthe target entity. For example, in a firewall connection from device A todevice B, A is described as the principal and B is described as the target.For a process injection by process C into target process D, process C isdescribed as the principal and process D is described as the target.
intermediary	Noun	repeated	Represents details on one or more intermediate entities processing activitydescribed in the event. This includes device details about a proxy serveror SMTP relay server. If an active event (that has a principal andpossibly target) passes through any intermediaries, they're added here.Intermediaries can impact the overall action, for example blocking ormodifying an ongoing request. A rule of thumb here is that 'principal','target', and description of the initial action should be the sameregardless of the intermediary or its action. A successful networkconnection from A->B should look the same in principal/target/intermediaryas one blocked by firewall C: principal: A, target: B (intermediary: C).
observer	Noun		Represents an observer entity (for example, a packet sniffer ornetwork-based vulnerability scanner), which is not a direct intermediary,but which observes and reports on the event in question.
about	Noun	repeated	Represents entities referenced by the event that are not otherwisedescribed in principal, src, target, intermediary or observer. For example,it could be used to track email file attachments, domains/URLs/IPs embeddedwithin an email body, and DLLs that are loaded during a PROCESS_LAUNCHevent.
security_result	SecurityResult	repeated	A list of security results.
network	Network		All network details go here, including sub-messages with details on eachprotocol (for example, DHCP, DNS, or HTTP).
extensions	Extensions		All other core, event-specific metadata goes in this message.Don't place protocol metadata in Extensions; put it in Network.
