Why Use Risk-Based Dashboards for Tracking Threat Trends?

Risk-based dashboards in Splunk Enterprise Security (ES) provide a structured way to track threats over time.

How Risk-Based Dashboards Help: Aggregate security events into risk scores Helps prioritize high-risk activities. Show historical trends of threat activity. Correlate multiple risk factors across different security events.

Example in Splunk ES: Scenario: A SOC team tracks insider threat activity over 6 months. The Risk-Based Dashboard shows:

Users with rising risk scores over time.

Patterns of malicious behavior (e.g., repeated failed logins + data exfiltration).

Correlation between different security alerts (e.g., phishing clicks malware execution).

Why Not the Other Options?

A. Event sampling -- Helps with performance optimization, not threat trend tracking. C. Summary indexing -- Stores precomputed data but is not designed for tracking risk trends. D. Data model acceleration -- Improves search speed, but doesn't track security trends.
