SPLK-5002 Exam Dumps : Splunk Certified Cybersecurity Defense Engineer

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.

Using Suppression in Splunk ES

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.

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.
