SPLK-5002 Splunk Certified Cybersecurity Defense Engineer Questions and Answers

Automating case management workflows in Splunk streamlines incident response and reduces manual overhead, allowing analysts to focus on higher-value tasks.

Main Benefits of Automating Case Management:

Reduces Response Times (C)

Automatically assigns cases to analysts based on predefined rules.

Triggers playbooks and workflows in Splunk SOAR to handle common incidents.

Improves Analyst Productivity (C)

Reduces time spent on manual case creation and updates.

Provides integrated case tracking across Splunk and ITSM tools (e.g., ServiceNow, Jira).

Aligning security processes with frameworks likeNIST Cybersecurity Framework (CSF)orMITRE ATT&CKprovides astructured approach to threat detection and response.

Benefits of Using Common Security Methodologies:

Enhancing Organizational Compliance (A)

Helps organizationsmeet regulatory requirements(e.g., NIST, ISO 27001, GDPR).

Ensuresconsistent security controlsare implemented.

Ensuring Standardized Threat Responses (C)

MITRE ATT&CK providesa common language for adversary techniques.

ImprovesSOC workflows by aligning detection and response strategies.

Lean Six Sigma (LSS) is a process improvement methodology used to enhance operational efficiency by reducing waste, eliminating errors, and improving consistency.

Primary Function of Lean Six Sigma in a Security Program:

Improves security operations efficiency by optimizing alert handling, threat hunting, and incident response workflows.

Reduces unnecessary steps in SOC processes, eliminating redundancies in threat detection and response.

Enhances decision-making by using data-driven analysis to improve security metrics and Key Performance Indicators (KPIs).

Improving Splunk’s indexing performance is crucial for handling large volumes of data efficiently while maintaining fast search speeds and optimized storage utilization.

Methods to Improve Indexing Performance:

Enable Indexer Clustering (A)

Distributes indexing load across multiple indexers.

Ensures high availability and fault tolerance by replicating indexed data.

Optimize Event Breaking Rules (D)

Defines clear event boundaries to reduce processing overhead.

Uses correctLINE_BREAKERandTRUNCATEsettings to improve parsing speed.

Notable events in Splunk Enterprise Security (ES) are triggered by correlation searches, which generate alerts when suspicious activity is detected. However, if too many false positives occur, analysts waste time investigating non-issues, reducing SOC efficiency.

How to Improve Notable Events Effectiveness:

Apply suppression rules to filter out known false positives and reduce alert fatigue.

Refine correlation searches by adjusting thresholds and tuning event detection logic.

Leverage risk-based alerting (RBA) to prioritize high-risk events.

Use adaptive response actions to enrich events dynamically.

By suppressing false positives, SOC analysts focus on real threats, making notable events more actionable. Thus, the correct answer is A. Applying suppression rules for false positives.
