Free and Premium Splunk SPLK-5002 Dumps Questions Answers

When organizations need to normalize event data from various sources, using Common Information Model (CIM) in Splunk is the best approach.

Why Use CIM for Normalized Event Data?

Standardizes Data Across Different Log Sources

CIM ensures consistent field names and formats across varied log types.

Makes searches, reports, and dashboards easier to manage.

Enables Faster and More Efficient Searches

Uses Data Models to accelerate search queries.

Reduces the need for custom field extractions.

The GET method in the Splunk REST API is used to retrieve data from a Splunk index. It allows users and automated scripts to fetch logs, alerts, or query results programmatically.

Key Points About GET in Splunk API:

Used for searching and retrieving logs from indexes.

Can be used to get search results, job status, and Splunk configuration details.

Common API endpoints include:

/services/search/jobs/{search_id}/results– Retrieves results of a completed search.

/services/search/jobs/export– Exports search results in real-time.

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).

Security metrics help organizations assess their security posture and make data-driven decisions.

Primary Purpose of Security Metrics in Splunk:

Measure Security Effectiveness (B)

Tracks incident response times, threat detection rates, and alert accuracy.

Helps SOC teams and leadership evaluate security program performance.

Improve Threat Detection & Incident Response

Identifies gaps in detection logic and false positives.

Helps fine-tune correlation searches and notable events.

An audit report provides an overview of security operations, compliance adherence, and past incidents, helping organizations ensure regulatory compliance and improve security posture.

Key Elements of an Audit Report:

Analysis of Past Incidents (A)

Includes details on security breaches, alerts, and investigations.

Helps identify recurring threats and security gaps.

Compliance Metrics (C)

Evaluates adherence to regulatory frameworks (e.g., NIST, ISO 27001, PCI-DSS, GDPR).

Measures risk scores, policy violations, and control effectiveness.

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.

Best Practices for Tuning Correlation Searches

Using Suppression in Splunk ES

In Splunk Enterprise Security (ES), notable events are generated by correlation searches, which are predefined searches designed to detect security incidents by analyzing logs and alerts from multiple data sources. Adding additional context to these notable events enhances their value for analysts and improves the efficiency of incident response.

To incorporate additional context, you can:

Use lookup tables to enrich data with information such as asset details, threat intelligence, and user identity.

Leverage KV Store or external enrichment sources like CMDB (Configuration Management Database) and identity management solutions.

Apply Splunk macros orevalcommands to transform and enhance event data dynamically.

Use Adaptive Response Actions in Splunk ES to pull additional information into a notable event.

The correct answer is A. By adding enriched fields during search execution, because enrichment occurs dynamically during search execution, ensuring that additional fields (such as geolocation, asset owner, and risk score) are included in the notable event.

Using Lookups for Data Enrichment

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.
