Eliminate Risk of Failure with Splunk SPLK-5002 Exam Dumps

Threat intelligence in Splunk Enterprise Security (ES) enhances SOC capabilities by identifying known attack patterns, suspicious activity, and malicious indicators.

Essential Steps in Developing Threat Intelligence:

Collecting Data from Trusted Sources (A)

Gather data from threat intelligence feeds (e.g., STIX, TAXII, OpenCTI, VirusTotal, AbuseIPDB).

Include internal logs, honeypots, and third-party security vendors.

Analyzing and Correlating Threat Data (C)

Use correlation searches to match known threat indicators against live data.

Identify patterns in network traffic, logs, and endpoint activity.

Operationalizing Intelligence Through Workflows (E)

Automate responses using Splunk SOAR (Security Orchestration, Automation, and Response).

Enhance alert prioritization by integrating intelligence into risk-based alerting (RBA).

Incorrect Answers: B. Conducting regular penetration tests -- Important for security, but not a core part of threat intelligence development. D. Creating dashboards for executives -- Helps in reporting but does not develop threat intelligence.

How to Use Threat Intelligence in Splunk

Aggregation policies in Splunk Enterprise Security (ES) are used to group related notable events, reducing alert fatigue and improving incident analysis.

Role of Aggregation Policies in Correlation Searches:

Group Related Notable Events (A)

Helps SOC analysts see a single consolidated event instead of multiple isolated alerts.

Uses common attributes like user, asset, or attack type to aggregate events.

Improves Incident Response Efficiency

Reduces the number of duplicate alerts, helping analysts focus on high-priority threats.

Incorrect Answers: B. To index events from multiple sources -- Correlation searches analyze indexed data but do not control indexing. C. To normalize event fields for dashboards -- Field normalization is handled by Splunk CIM (Common Information Model). D. To automate responses to critical events -- While SOAR automates response actions, aggregation focuses on event grouping.

Best Practices for Correlation Searches

Splunk SOAR (Security Orchestration, Automation, and Response) improves security operations by automating routine tasks.

1. Faster Incident Resolution (A)

SOAR playbooks reduce response time from hours to minutes.

Example:

A malicious IP is automatically blocked in the firewall after detection.

2. Scaling Manual Efforts (C)

Automation allows security teams to handle more incidents without increasing headcount.

Example:

Instead of manually reviewing phishing emails, SOAR triages them automatically.

3. Consistent Task Execution (D)

Ensures standardized responses to security incidents.

Example:

Every malware alert follows the same containment process.

Incorrect Answers:

B . Reducing false positives SOAR automates response but does not inherently reduce false positives (SIEM tuning does).

E . Eliminating all human intervention Human analysts are still needed for decision-making.

Best Practices for SOAR Implementation

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.
