SPLK-5001 Exam Dumps : Splunk Certified Cybersecurity Defense Analyst

In Splunk Enterprise Security, theRisk Event Timelineprovides a chronological view of risk events associated with a particular Risk Object, such as a user or device. This timeline helps analysts visualize and understand the sequence and nature of risk events over time, aiding in the investigation of security incidents.

Risk Event Timeline:

The Risk Event Timeline is accessible by clicking the risk event count associated with a Risk Object in the Incident Review dashboard. This action opens up the timeline view, which provides a detailed chronological perspective on how risk events have unfolded.

This feature is particularly useful for tracking the progression of threats and understanding the context of incidents.

Incorrect Options:

A. Running the Risk Analysis Adaptive Response action within the Notable Event:This option pertains to running a response action rather than visualizing risk events over time.

B. Via a workflow action for the Risk Investigation dashboard:Although workflow actions can lead to various dashboards, the specific visualization described is accessed via the Risk Event Timeline.

C. Via the Risk Analysis dashboard under the Security Intelligence tab in Enterprise Security:While this dashboard provides valuable insights into risk data, the specific chronological visualization is found in the Risk Event Timeline.

Adaptive Response Actions (ARAs)in Splunk Enterprise Security enable analysts to initiate automated or semi-automated remediation workflows directly from ES dashboards or investigations without leaving the interface. When integrated with Splunk SOAR (Security Orchestration, Automation, and Response), ARAs can trigger playbooks designed to execute containment actions on compromised devices and simultaneously update the original investigation or notable event.

Anadaptive response actionis tightly integrated with ES findings and provides immediate feedback into the investigation workflow.

Event-level and field-level workflow actions may support initiating external processes but are less integrated or standardized than ARAs.

Alert actions typically trigger notifications, not complex remediation playbooks.

TheSplunk Enterprise Security documentationhighlights ARAs as a key component for orchestrated response enabling analysts to act decisively within the ES context, ensuring containment activities are both tracked and correlated with initial findings.

Abaselineis a representation or model of normal network activity, capturing expected patterns and behaviors over time. It serves as a reference point against which anomalies and deviations can be detected. By establishing a baseline, security analysts can identify unusual activities that might indicate security incidents.

Baselineinvolves statistical analysis of historical data to define normal ranges for metrics like traffic volume, connection rates, or login times.

Clusterrefers to grouping similar data points, often used in anomaly detection but not synonymous with a model of normal activity.

Time seriesis a sequence of data points indexed in time order, useful for monitoring trends but not specifically a model of normalcy.

Data modelrefers to an abstract schema for organizing data, such as Splunk’s CIM data models.

TheSplunk Cybersecurity Defense Analyst Study Guidehighlights baselining as a fundamental technique in anomaly detection and network security monitoring.
