The new CompTIA CySA+ V4 CS0-004 exam is the updated version of the CS0-003 exam and reflects the modern responsibilities of cybersecurity analysts working in security operations, vulnerability management, incident response, cloud security, hybrid environments, and AI-supported defense. To help you pass the exam easily, the most valid CompTIA CySA+ Certification CS0-004 Prep Guide with Practice Test Questions from PassQuestion gives candidates a focused and practical way to review the latest exam objectives, understand real SOC scenarios, strengthen vulnerability analysis skills, and become familiar with the question styles tested in the new CySA+ V4 exam.

What Is the CompTIA CySA+ CS0-004 Exam?

The CompTIA Cybersecurity Analyst (CySA+) CS0-004 certification exam validates the skills required to detect, analyze, and respond to cybersecurity threats in modern environments. It is designed for professionals who work with security monitoring, vulnerability management, incident investigation, threat intelligence, and security reporting.

CompTIA released the updated CySA+ exam on June 23, 2026, stating that the new exam aligns the credential with how cybersecurity teams detect and respond to increasingly sophisticated threats, including the shift toward AI-driven cyber defense.

CS0-004 Replaces CS0-003: What Candidates Should Know

The CS0-004 CySA+ V4 exam is the updated version of CS0-003. The older CS0-003 exam is scheduled to retire on December 22, 2026, giving candidates a transition period to decide whether to complete the older version or prepare for the new CS0-004 objectives.

For most new candidates, CS0-004 is the better preparation path because it reflects current cybersecurity operations. Compared with CS0-003, the new version places stronger emphasis on modern SOC workflows, cloud and hybrid environments, AI in security operations, process improvement, risk-based vulnerability prioritization, and clearer communication of security findings.

Skills You Will Learn with CySA+ V4

Preparing for the CS0-004 exam helps candidates build job-ready cybersecurity skills, including how to:

• Identify and investigate suspicious activity across networks, endpoints, cloud platforms, and identity systems
• Monitor and analyze security data with SIEM, EDR, XDR, packet analysis, and threat intelligence tools
• Identify, prioritize, and mitigate vulnerabilities using risk-based methods
• Respond to incidents with structured processes and real-world investigation techniques
• Communicate security risks through reports, dashboards, metrics, and stakeholder updates
• Apply security practices across cloud and hybrid environments
• Understand the benefits, risks, and governance considerations of AI in security operations

CompTIA CySA+ CS0-004 Exam Details

CompTIA's official CS0-004 exam objectives list the exam as having a maximum of 85 questions, multiple-choice and performance-based formats, a 165-minute test duration, a recommended four years of hands-on SOC or vulnerability analyst experience, and a passing score of 750.

CS0-004 Exam Objectives at a Glance

The largest domain is Security Operations, followed by Vulnerability Management and Incident Response and Management. Candidates should prepare with both conceptual knowledge and hands-on scenario practice because the exam includes performance-based questions.

Security Operations (34%)

• Explain system and network architecture concepts in security operations: Security architecture components, identity concepts, and logging practices that support secure environments.
• Analyze indicators of potential malicious activity: Suspicious activity across networks, endpoints, cloud, and identity systems.
• Use tools to determine malicious activity: SIEM, EDR, packet analysis tools, and threat intelligence platforms.
• Explain threat intelligence and threat-hunting concepts: Frameworks, data sources, and methods used to identify and investigate threats.
• Describe efficiency and process improvement in security operations: Automation, workflows, and processes used to improve operational efficiency.
• Summarize concepts related to the use of AI in security operations: Use cases, risks, and governance considerations.

Vulnerability Management (26%)

• Implement the appropriate vulnerability scanning method: Tools and techniques used to identify vulnerabilities across systems, networks, and applications.
• Analyze output from vulnerability assessment tools: Vulnerabilities, findings, and security gaps identified through scan results.
• Prioritize and mitigate vulnerabilities: Risk-based approaches using scoring systems, threat intelligence, and business context.
• Explain concepts related to control types, risks, and vulnerability management: Controls, policies, and compliance practices used to manage risk.

Incident Response and Management (24%)

• Summarize concepts related to attack methodology frameworks: Models such as MITRE ATT&CK and the Cyber Kill Chain.
• Outline the incident response process: Phases including preparation, detection, analysis, containment, eradication, and recovery.
• Implement incident response techniques: Triage, evidence handling, escalation, remediation, and root cause identification.

Reporting and Communication (16%)

• Explain vulnerability management reporting and communication: Reports, dashboards, and communication activities used to present findings and support escalation during security events.
• Describe security operations, incident response reporting, and communication: Incident documentation, post-incident reviews, and metrics such as detection time, response time, and remediation effectiveness.

How to Prepare for the CS0-004 CySA+ V4 Exam

1. Review the Latest CS0-004 Exam Objectives

Start your preparation with the four official domains: Security Operations, Vulnerability Management, Incident Response and Management, and Reporting and Communication. Pay close attention to new V4 topics such as AI in security operations, cloud infrastructure assessment, automation, SOAR, risk-based vulnerability prioritization, and modern reporting metrics.

2. Build Hands-On SOC and Vulnerability Analysis Skills

CySA+ is not only a theory exam. Practice using SIEM dashboards, EDR alerts, packet captures, vulnerability scan results, threat intelligence reports, and incident response playbooks. Hands-on experience will help you answer scenario-based and performance-based questions more confidently.

3. Practice Incident Response Scenarios

Review the full incident response process and practice how to classify alerts, gather evidence, build timelines, determine severity, isolate affected systems, escalate incidents, verify remediation, and document lessons learned. These skills are central to the daily work of a cybersecurity analyst.

4. Strengthen Vulnerability Prioritization

Do not study vulnerability management as a simple scanning topic. Learn how to evaluate exploitability, asset value, active exploitation, business impact, patch availability, compensating controls, and remediation validation. The exam expects risk-based thinking.

5. Use Valid CS0-004 Practice Test Questions

Valid CompTIA CySA+ Certification CS0-004 Practice Test Questions from PassQuestion can help you understand the exam format, test your knowledge of important objectives, and identify weak areas before the real exam. Practice questions are especially useful for SIEM analysis, EDR alerts, vulnerability prioritization, incident response steps, AI-related security operations, and reporting scenarios.

Final Thoughts

The CompTIA CySA+ V4 CS0-004 exam is an important update for cybersecurity professionals who want to prove their ability to work in modern security operations and vulnerability management roles. With CS0-003 retiring on December 22, 2026, candidates should understand the transition and prepare with the latest CS0-004 exam objectives.
