SPLK-5001 Exam Dumps - Splunk Cybersecurity Defense Analyst Questions and Answers

Thefile_aclfield, which contains access controls associated with files affected by an event, is part of theEndpointdata model in Splunk. The Endpoint data model is designed to include information related to file access, process activity, and user activity on endpoints. Fields likefile_aclare critical for understanding permissions and potential security risks associated with file access and manipulation, which are key aspects of endpoint security monitoring.

Under the General Data Protection Regulation (GDPR), Personal Data is any information relating to an identified or identifiable natural person. An individual's address, combined with their first and last name, clearly identifies a person, making it Personal Data under GDPR. The other options provided do not meet the GDPR criteria for Personal Data: the birth date of an unidentified user does not identify a person, the name of a deceased individual is not covered under GDPR, and a company’s registration number pertains to an entity rather than a natural person.

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.

TheCHMC (Cybersecurity Health Management Capability)framework was created specifically to assess and measure an organization's cybersecurity maturity. Unlike compliance frameworks that focus on specific regulatory requirements (e.g., PCI-DSS for payment card security, GDPR for data privacy, or FISMA for federal information security management), CHMC provides a structured maturity model that evaluates the effectiveness and sophistication of cybersecurity practices within an enterprise.

TheCHMCframework benchmarks capabilities across various domains such as governance, risk management, incident response, and security operations, enabling organizations to identify gaps and prioritize improvements systematically.

PCI-DSSis a compliance standard aimed at securing payment card data.

GDPRgoverns data protection and privacy for individuals in the EU.

FISMAmandates federal agencies to implement information security programs but does not itself provide a maturity model.

TheSplunk Cybersecurity Defense Analyst materialshighlight that maturity models like CHMC help organizations progress beyond basic compliance, fostering a culture of continuous improvement in cybersecurity posture.

In the context of theTTP (Tactics, Techniques, and Procedures)framework used in cybersecurity, the termProcedurerefers to the specific implementation or method used by an adversary to execute an attack or achieve an objective. Here, "LoudWiner" represents a particular malware or tool used by the adversary to hijack resources for crypto mining, which is an actualprocedure—the concrete steps or methods taken to accomplish the broader technique or tactic.

Tacticis the adversary’s goal or objective (e.g., resource hijacking for financial gain).

Techniqueis a general method used to achieve the tactic (e.g., crypto mining via malware).

Procedureis the specific variant or implementation of the technique (e.g., using LoudWiner malware).

Problemis not a recognized element in the TTP framework.

TheMITRE ATT&CK frameworkdefines procedures as real-world implementations of techniques by adversaries. Splunk’s cybersecurity analyst materials emphasize understanding these distinctions to better map observed adversary behavior.

In a successful Continuous Monitoring initiative, when an analyst identifies the need for more context or additional information, the request typically escalates to aSecurity Engineer. Security Engineers are responsible for the integration and configuration of additional data sources, and they can alter correlation rules or enhance data ingestion pipelines to provide the necessary context for analysts.

Security Engineer:

Manages and optimizes security tools and systems, including SIEM (like Splunk), and ensures that the necessary data sources are integrated into the monitoring environment.

Responsible for creating and tuning correlation rules and maintaining the infrastructure required for continuous monitoring.

Incorrect Options:

A. SOC Manager:Oversees the overall operations of the SOC but does not typically handle the technical integration of data sources.

B. Security Analyst:Primarily focuses on monitoring, detecting, and responding to security incidents, rather than configuring systems.

D. Security Architect:Focuses on the overall design of the security infrastructure, not on the day-to-day integration of data sources.

TheData Inventoryfeature in Splunk Security Essentials provides analysts with a comprehensive listing of all currently onboarded data sources within the Splunk environment. This enables users to quickly identify what data is available for security use cases, allowing targeted viewing and analysis based on the indexed datasets.

Data Inventoryconsolidates metadata about indexes, sourcetypes, and data volume, helping analysts understand their security coverage.

Security Data Journeyis a guided workflow for progressing through security content and maturity but does not specifically list data sources.

Security Contentrefers to detection content like correlation searches, dashboards, and reports.

Data Source Onboarding Guideshelp users onboard new data sources but do not reflect the current onboarded data inventory.

TheSplunk Security Essentials documentationhighlights Data Inventory as a key tool for bridging visibility gaps and accelerating content deployment aligned with available data.

When querying accelerated data models using thetstatscommand in Splunk, the argumentsummariesonly=trueensures the search uses only the accelerated summary data, not the raw events. This parameter restricts the search to the precomputed, optimized data summaries, providing much faster query performance.

summariesonly=trueexplicitly directs Splunk to use accelerated data, bypassing slower raw data scans.

Other options like accelerate=true or dataset=accelerated are invalid or misused in this context.

datamodel=accelerated is also incorrect since the datamodel argument requires the name of the data model, not a mode.

TheSplunk tstats command documentationandCybersecurity Defense Analyst Study Guideboth specify that summariesonly=true is critical for efficient querying of accelerated data models such as the Network Traffic Data Model.

The primary difference between a Distributed Denial of Service (DDoS) attack and a Denial of Service (DoS) attack is in the source of the attack. ADDoSattack involves multiple compromised systems (often part of a botnet) attacking a single target, overwhelming it with traffic or requests. In contrast, aDoSattack typically involves a single source attacking the target. The goal of both attacks is to make a service unavailable, but DDoS attacks are usually more difficult to defend against because of their distributed nature.

In Splunk,default metadatarefers to automatically assigned attributes associated with each event at indexing time that help identify and organize data. These include:

Source: The origin of the data (file, network port, etc.)

Timestamps: The time the event occurred, extracted from the event or assigned at ingestion

Host name: The name of the host generating the event

Event descriptionis not a default metadata field in Splunk. It is typically user-defined or derived from the event content and is not assigned automatically by Splunk.

TheSplunk documentationon event metadata clarifies these standard fields, which are crucial for search filtering and data organization.
