Objective 2.1

Cybersecurity Defense Engineer

Create and tune detections (i.e. Correlation Search)

Objective 2.1 sits in Detection Engineering, which carries 40% of the Cybersecurity Defense Engineer exam. The questions below are original, written from the official objective title above, and each explanation cites the Splunk page it rests on.

A worked example

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

2-1Detection Engineering

An engineer installs Enterprise Security and finds most correlation searches turned off. What reason does Splunk give?

So upgrades never overwrite themUpgrade behaviour is handled separately from the default state.
So the licence is not exceededLicence use is driven by data volume rather than by enabled searches.
So the indexers stay idleIndexer load is a consequence rather than the documented reason.
So you choose relevant onesCorrect · your answerCorrect.

Correct.

Concept

Turning everything on floods a queue with alerts nobody has agreed to work. Starting from off makes each enabled rule a decision somebody made.

Why D

Splunk documents that Enterprise Security installs with most correlation searches disabled so that you can choose the searches most relevant to your security use cases.

Source

Enable correlation searches to start running adaptive response actions and receiving notable events . Splunk Enterprise Security installs with most correlation searches disabled so that you can choose the searches that are most relevant to your security use cases.

An engineer is asked to reduce cluster load from correlation searches. Which change does Splunk document as generally lighter?

Sample question 2 of 3

2-1Detection Engineering

An engineer must not lose detections when a search cannot run at its scheduled time. Which schedule type does Splunk document for that?

Sample question 3 of 3

2-1Detection Engineering

An engineer sets both a schedule window and a schedule priority on a correlation search. What does Splunk say about that?
