Use context-enriched data in UDM Search

To enable security analysts during an investigation, Google Security Operations ingests contextual data from different sources, normalizes the ingested data, and provides additional context about artifacts in a customer environment. This document provides examples of how analysts can use contextually-enriched data in UDM Search.

For more information about data enrichment, see How Google Security Operations enriches event and entity data.

The following example finds a process module that loads a kernel32.dll file into a particular process.

metadata.event_type = "PROCESS_MODULE_LOAD" AND
target.file.file_type = "FILE_TYPE_PE_EXE" AND
target.file.pe_file.imports.library = "kernel32.dll"

Google Security Operations enriches events containing external IP addresses with geolocation data. This provides additional context during an investigation. This document explains how you can use geolocation-enriched fields when performing investigative searches.

Geolocation-enriched UDM fields can be accessed through UDM search as shown in the following examples.

Search by country name (country_or_region)

target.ip_geo_artifact.location.country_or_region = "Netherlands" OR
principal.ip_geo_artifact.location.country_or_region = "Netherlands"

Search by state

target.ip_geo_artifact.location.state = "North Holland" OR
principal.ip_geo_artifact.location.state = "North Holland"

Search by longitude and latitude

principal.location.region_latitude = 52.520588 AND principal.location.region_longitude = 4.788474

Search by unauthorized target geographies

metadata.event_type = "NETWORK_CONNECTION" AND
    target.ip_geo_artifact.location.country_or_region = "Cuba" OR
    target.ip_geo_artifact.location.country_or_region = "Iran" OR
    target.ip_geo_artifact.location.country_or_region = "North Korea" OR
    target.ip_geo_artifact.location.country_or_region = "Russia" OR
    target.ip_geo_artifact.location.country_or_region = "Syria"

Search by Autonomous System Number (ASN)

metadata.event_type = "NETWORK_CONNECTION" AND
( = 33915

By organization name

metadata.event_type = "NETWORK_CONNECTION" AND
( = "google"

By carrier name

metadata.event_type = "NETWORK_CONNECTION" AND
( = "google llc"

By DNS domain

metadata.event_type = "NETWORK_CONNECTION" AND
( = ""

View geolocation-enriched fields in the UDM grid

Geolocation-enriched fields are displayed in UDM grid views including those in UDM Search, Detection View, User View, and Event Viewer.
