Matched threats are organized into two sections, described below. Within each section, matched threats are shown in reverse chronological order, with the most recent at the top. All mapped fields are displayed for each matched threat.

Threat match detected

The Threat match detected section is only populated with indicator match details if you’re examining an alert that was generated from an indicator match rule. Indicator matches occur when alert field values match with threat intelligence data you’ve ingested.

Fields enriched with threat intelligence

Threat intelligence can also be found on alerts that weren’t generated from indicator match rules. To find this information, Elastic Security queries alert documents from the past 30 days and searches for fields that contain known threat intelligence. If any are found, they’re logged in this section.

When searching for threat intelligence, Elastic Security queries the alert document for the following fields:

Correlationsedit

The Correlations overview shows how an alert is related to other alerts and offers ways to investigate related alerts. Use this information to quickly find patterns between alerts and then take action.

Prevalenceedit

The Prevalence overview shows whether data from the alert was frequently observed on other host events from the last 30 days. Prevalence calculations use values from the alert’s highlighted fields. Highlighted field values that are observed on less than 10% of hosts in your environment are considered uncommon (not prevalent) and are listed individually in the Prevalence overview. Highlighted field values that are observed on more than 10% of hosts in your environment are considered common (prevalent) and are described as frequently observed in the Prevalence overview.

Expanded prevalence viewedit

From the right panel, click Prevalence to open the expanded Prevalence view within the left panel. Examine the table to understand the alert’s relationship with other alerts, events, users, and hosts.
