Shown solved, with the whole explanation open: this is what every question here carries.

6-2Threat Hunting and Remediation

An analyst wants to find the low-scoring behaviours that never trip a single detection. Which documented approach in Enterprise Security surfaces them?

Disabling suppression rulesSuppression rules control noise rather than reveal slow activity.
Raising every detection severityRaising severity everywhere increases volume rather than insight.
Shortening the search windowA shorter window hides exactly the pattern being sought.
Aggregating risk over timeCorrect · your answerCorrect.

Correct.

Checked against help.splunk.com, August 2026

Concept

A hunt for slow activity needs a memory. Adding contributions across days is what makes a pattern visible that no single day contains.

Why D

Splunk documents risk-based alerting as detecting complex behaviour over a period of time instead of a point in time, with alerting criteria over varying durations.

Source

Similarly, RBA helps detect complex behavior over a period of time instead of a point in time. For example, an impatient hacker might try various techniques to attack a single server over a period of time.
