Objective 3.2

Cybersecurity Defense Analyst

Describe SIEM best practices and basic operation concepts of Splunk Enterprise Security, including the interaction between CIM, Data Models and acceleration, Asset and Identity frameworks, and common CIM fields that may be used in investigations

Objective 3.2 sits in Defenses, Data Sources, and SIEM Best Practices, which carries 20% of the Cybersecurity Defense Analyst exam. The questions below are original, written from the official objective title above, and each explanation cites the Splunk page it rests on.

3-2Defenses, Data Sources, and SIEM Best Practices

An analyst asks what the Splunk Common Information Model is. Which description matches the documentation?

A licensing tier for security dataIt is an add-on rather than a licensing tier.
A set of index time field extractionsThe CIM acts at search time rather than at index time.
A shared semantic model for dataCorrect · your answerCorrect.
A replacement for the DMTF standardSplunk states the CIM is unaffiliated with the DMTF model.

Correct.

Concept

Normalising after indexing rather than before it keeps the raw record intact. The same events can then be read a second way when the first turns out to be wrong.

Why C

Splunk documents the CIM as a shared semantic model focused on extracting value from data, implemented as an add-on of data models, documentation and tools.

Source

The Splunk Common Information Model (CIM) is a shared semantic model focused on extracting value from data. The CIM is implemented as an add-on that contains a collection of data models, documentation, and tools that support the consistent, normalized treatment of data for maximum efficiency at search time.
