The Splunk Data Pipeline consists of multiple stages that process incoming data from ingestion to visualization.

Main Steps of the Splunk Data Pipeline:

Input Phase (C)

Splunk collects raw data from logs, applications, network traffic, and endpoints.

Supports various data sources like syslog, APIs, cloud services, and agents (e.g., Universal Forwarders).

Parsing (D)

Splunk breaks incoming data into events and extracts metadata fields.

Removes duplicates, formats timestamps, and applies transformations.

Indexing (A)

Stores parsed events into indexes for efficient searching.

Supports data retention policies, compression, and search optimization.

Aligning security processes with frameworks like NIST Cybersecurity Framework (CSF) or MITRE ATT & CK provides a structured approach to threat detection and response .

Benefits of Using Common Security Methodologies:

Enhancing Organizational Compliance (A)

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

Ensures consistent security controls are implemented.

Ensuring Standardized Threat Responses (C)

MITRE ATT & CK provides a common language for adversary techniques .

Improves SOC workflows by aligning detection and response strategies .

Splunk allows dynamic field extraction to enhance data analysis without modifying raw indexed data.

Search-Time Field Extraction:

Extracts fields on-demand when running searches.

Uses Splunk’s Field Extraction Engine ( rex , spath , or automatic field discovery).

Minimizes indexing overhead by keeping the raw data unchanged.

Updating the SOP for Handling Phishing Incidents

A Standard Operating Procedure (SOP) should focus on prevention, detection, and response .

✅ 1. Documenting Steps for User Awareness Training (C)

Training employees helps prevent phishing incidents.

Example:

Teach users to identify phishing emails and report them via a Splunk SOAR playbook.

❌ Incorrect Answers:

A. Ensuring all reports are manually verified by analysts → Automation (via SOAR) should be used for initial triage.

B. Automating the isolation of suspected phishing emails → Automation is useful, but user education prevents incidents.

D. Reporting incidents to the executive board immediately → Only major security breaches should be escalated to executives.
