Splunk SPLK-5001 Passing Score

The correct order of the examples listed corresponds toTactic, Technique, Procedurein the TTP framework:

Tactic:The high-level goal or objective an adversary tries to accomplish. "Extend movement" (likely meant as "Lateral movement") or "Exploiting a remote service" are tactics that describewhatthe adversary wants to do.

Technique:The general method or approach used to achieve the tactic. "Exploiting a remote service" is a technique, detailing the type of action used in pursuit of the tactic.

Procedure:The specific implementation or instance of a technique. "Use EternalBlue to exploit a remote SMB server" is a concrete procedure, an exact exploit tool or method used.

This hierarchy is fundamental to frameworks likeMITRE ATT&CK, which guides how analysts categorize and investigate adversary behaviors.

The Common Information Model (CIM) in Splunk is a crucial component that allows for the normalization and standardization of data across various sources. By using CIM, disparate data sources can be mapped to a common schema, which makes it significantly easier to correlate and analyze data across different logs and systems.

Purpose of CIM:CIM provides a standardized format for fields and event types across various data sources in Splunk. This normalization allows analysts to use consistent field names and structures when performing searches, regardless of the original data source's format.

Benefit of Easier Correlation:One of the primary challenges in security operations is correlating data from different sources—like firewalls, intrusion detection systems (IDS), endpoint security solutions, and network logs—to identify potential security incidents. CIM facilitates this by ensuring that all relevant data adheres to a common schema, enabling seamless correlation and analysis. For example, CIM allows a security analyst to write a single query that can apply to data from multiple sources, simplifying the detection of complex threats.

How it Works:CIM is implemented through data models in Splunk, which act as a blueprint for mapping and transforming raw data into a structured format. These data models cover a wide range of security domains, such as authentication, network traffic, and malware, ensuring that data from different security tools can be easily integrated and analyzed together.

Use Cases:The primary use cases for CIM include:

Search and Reporting:Creating efficient and standardized searches that apply across multiple data sources.

Dashboards and Visualizations:Building dashboards that pull in data from various sources in a consistent manner.

Correlation Searches:Developing correlation searches that detect patterns or anomalies across different types of data, enhancing threat detection.

TheAccess dashboardsin Splunk Enterprise Security focus on authentication, login activity, access controls, and related security events. These dashboards provide analysts with insights into successful and failed authentications, anomalous access patterns, and identity-related events.

Audit dashboardsgenerally focus on compliance and audit logs.

Asset and Identity dashboardsprovide broader context about users and devices but are not specifically focused on authentication events.

Endpoint dashboardsconcentrate on host and endpoint telemetry such as process execution and file activity.

Splunk’sEnterprise Security User Guideclearly identifies Access dashboards as the primary interface for monitoring and investigating authentication and access behaviors.

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.
