How to Pass the CompTIA CySA+ Exam in 2026 (CS0-003)

What is the CompTIA CySA+ CS0-003?

The CompTIA Cybersecurity Analyst (CySA+) is an intermediate cybersecurity certification positioned above Security+ and below CASP+ in the CompTIA career pathway. The current version, CS0-003, launched in June 2023 and emphasizes threat hunting, behavioral analytics, SIEM log analysis, and vulnerability management workflows used by SOC analysts and threat intelligence professionals.

CySA+ holds DoD 8570 approval under the IAT Level II and CSSP Analyst categories, making it a required credential for many U.S. federal cybersecurity positions. For private sector candidates, it validates hands-on analyst capabilities that Security+ alone does not demonstrate.

CompTIA recommends Security+ and at least four years of hands-on experience in a security or related IT role before attempting CySA+. Candidates who have read our CompTIA Security+ study guide will have a solid baseline for the foundational security concepts CySA+ builds on.

CySA+ CS0-003 Exam Format

• Maximum questions: 85 (includes unscored beta items)
• Duration: 165 minutes
• Question types: Multiple choice plus performance-based questions (PBQs)
• Passing score: 750 out of 900
• Cost: $392 USD (CompTIA's current associate exam pricing)
• Delivery: Pearson VUE testing center or online proctored

The 165-minute time limit is generous but performance-based questions consume significantly more time than multiple choice items. Budget 10 to 20 minutes per PBQ and leave time at the end to review flagged multiple choice questions.

CySA+ Exam Domains and Percentages

CS0-003 is organized into four domains. Study allocation should reflect these weightings:

• Security Operations (33%): The largest domain. Covers threat intelligence lifecycle, SIEM operations, log analysis, endpoint detection, and security monitoring workflows.
• Vulnerability Management (30%): Scanning methodologies, vulnerability scoring (CVSS), remediation prioritization, compliance frameworks, and patch management cycles.
• Incident Response and Management (20%): Incident classification, containment strategies, forensic evidence collection, post-incident analysis, and communication protocols.
• Reporting and Communication (17%): Vulnerability report creation, stakeholder communication, metrics and KPIs for security programs, and risk appetite documentation.

Security Operations and Vulnerability Management together account for 63% of the exam. If you have limited study time, these two domains deserve the most attention.

Key Differences from Security+

CySA+ tests a fundamentally different skill set than Security+. Security+ validates knowledge of security concepts: what is a firewall, what is PKI, how does multi-factor authentication work. CySA+ tests analyst judgment: given this SIEM alert, what is the likely threat actor technique, and what is your first containment action.

• Security+: Knowledge-based, conceptual, broad coverage of security domains
• CySA+: Scenario-based, applied analyst decisions, SIEM log interpretation, threat hunting workflows

The practical implication for study: CySA+ requires you to read simulated log output, identify indicators of compromise, map behaviors to MITRE ATT&CK techniques, and recommend actions. Passive reading is less effective here than hands-on labs and scenario practice. For a detailed comparison of these two credentials, see our Security+ vs CySA+ comparison.

Tools and Technologies Covered

CySA+ is explicitly tool-agnostic, but the exam tests familiarity with the following categories and representative tools:

• SIEM platforms: Splunk basics including search processing language (SPL) queries, alert configurations, and dashboard interpretation. You do not need Splunk admin skills, but you must understand SIEM concepts and basic query logic.
• Vulnerability scanners: Nessus and Qualys are the most referenced. Understand scan types (credentialed vs uncredentialed), false positive rates, and how CVSS scores inform remediation priority.
• Network analysis: Wireshark for packet capture analysis. The exam may present PBQs requiring you to identify suspicious traffic patterns from a pcap summary.
• Threat intelligence frameworks: MITRE ATT&CK is the most tested non-CompTIA content on CySA+. STIX and TAXII for structured threat intelligence sharing.

The MITRE ATT&CK Framework: Most Tested External Content

MITRE ATT&CK appears throughout the exam as the standard vocabulary for describing adversary behavior. You must understand the framework structure: 14 tactics representing attacker goals (Initial Access, Execution, Persistence, etc.), techniques representing specific methods to achieve each tactic, and sub-techniques providing additional specificity.

CySA+ questions will describe attack behaviors and ask you to identify the corresponding ATT&CK tactic or technique, or present a technique and ask what defender action disrupts it. Spend at least two to three study sessions reviewing the ATT&CK matrix directly on the MITRE website. The navigate.mitre.org interface allows you to highlight relevant techniques for specific threat groups, which is useful for understanding how real-world adversaries combine techniques.

Performance-Based Question Strategies

CySA+ PBQs present simulated environments: a Splunk dashboard with alerts, a network diagram with traffic anomalies, or a vulnerability scan output requiring triage decisions. The most common mistake candidates make on PBQs is spending too long on them at the start of the exam and running out of time on multiple choice questions.

Recommended approach: attempt each PBQ when you reach it, give yourself 10 to 15 minutes, answer what you can confidently, then flag and move on. Return to PBQs at the end with remaining time. For log analysis PBQs, look for known attack signatures first: unusual port numbers, base64-encoded commands in web logs, or authentication failures followed by a success from the same source.

How AI Tutoring Helps with Scenario-Based Questions

CySA+ scenario questions require you to reason through attacker techniques and defender responses simultaneously. When you answer these incorrectly, the gap is often in the connection between the presented scenario and the underlying framework concept, not in factual recall.

Certify Copilot AI captures the scenario and all answer options from your screen, then explains which ATT&CK technique or SOC process the question is testing, why each answer option applies or does not apply, and what mental model to use for similar scenarios. This is faster and more contextual than re-reading textbook chapters to find the relevant section.

Frequently Asked Questions

• Should I get Security+ before CySA+? Strongly recommended, not mandatory. CompTIA recommends Security+ as a baseline. Candidates without Security+ foundation knowledge consistently report CySA+ as significantly more difficult. The exception is candidates with 4+ years of hands-on SOC experience who have the practical knowledge even without the credential.
• How long does CySA+ take to study for? For candidates with Security+ and some SOC experience: 80 to 120 hours (8 to 12 weeks at 10 hours per week). For candidates with only Security+ and limited hands-on experience: 120 to 160 hours.
• Is CySA+ worth it for non-government roles? Yes. Even outside DoD environments, CySA+ is increasingly requested for SOC analyst and threat intelligence roles. It demonstrates a level of practical analyst capability that Security+ alone does not signal.
