CySA+
CompTIA CySA+ (CS0-003)
CompTIA CySA+ (CS0-003) is the intermediate-level cybersecurity analyst certification covering security operations, threat intelligence, vulnerability management, incident response, and reporting. It bridges the gap between entry-level Security+ and advanced SecurityX, targeting SOC analysts, threat hunters, and incident responders in Tier 2/3 security operations roles. CySA+ meets DoD 8140 requirements for CSSP Analyst roles.

Sample CySA+ Practice Questions
Q1.Which log management best practice ensures that logs collected across multiple systems remain accurate and can be correlated effectively during incident investigations?
- Storing logs locally on each host for integrity
- Using synchronized timestamps across all logging devicesCorrect
- Collecting only critical error logs to reduce volume
- Encrypting logs only after collection to optimize speed
Using synchronized timestamps (e.g., via NTP) ensures accurate temporal correlation across diverse log sources. Storing logs locally risks loss or tampering. Collecting only critical logs may omit important data for investigations. Encrypting logs after collection delays protection and risks exposure during transit.
Q2.Which patch prioritization strategy best aligns with compliance requirements while addressing organizational risk in a continuously evolving threat landscape?
- Prioritize patches solely based on vendor severity ratings without considering organizational context.
- Use a dynamic risk scoring model incorporating severity, asset value, exploit availability, and compliance mandates.Correct
- Patch only after annual audits to maintain compliance documentation.
- Focus patching efforts exclusively on legacy systems to avoid newer software disruptions.
A dynamic risk scoring model balances compliance and organizational risk by considering multiple relevant factors. Option 0 ignores internal context. Option 2 delays critical remediation, risking compliance and security. Option 3 neglects newer systems that may be more vulnerable, risking overall security posture.
Q3.During log analysis, an analyst finds inconsistencies in timestamps across multiple sources. What is the best approach to ensure accurate correlation of events during incident investigation?
- Adjust all logs to the same time zone and synchronize using Network Time Protocol (NTP) recordsCorrect
- Ignore logs with inconsistent timestamps as unreliable
- Use only the logs from the system with the most frequent entries
- Manually estimate event times based on user reports
Adjusting logs to a common time zone and synchronizing timestamps using NTP ensures accurate event correlation. Ignoring logs risks losing important data. Using only one system's logs limits perspective and may omit critical events. Manual estimation is error-prone and unreliable.
CySA+ Frequently Asked Questions
What does CySA+ stand for?
CySA+ stands for CompTIA CySA+ (CS0-003). It is administered by CompTIA.
Who administers the CySA+?
The CompTIA CySA+ (CS0-003) (CySA+) is administered by CompTIA. For official information, visit the CompTIA website.
How many questions is the CySA+?
The CySA+ consists of 85 questions. Candidates are given 165 minutes to complete the exam.
How many practice questions does C3RT have for the CySA+?
The C3RT app includes 5,500 practice questions for the CySA+, along with 1,500 flashcards, 300 concept reels, and 400 concept cards.
What is the passing score for the CySA+?
The passing score for the CySA+ is 750/900, as set by CompTIA. Scoring methodology and passing standards may be updated periodically. Always verify current requirements with the governing body.
How much does the CySA+ exam cost?
The CySA+ exam fee is $392 USD. This fee is set by CompTIA and may vary by testing centre, region, or membership status. Additional fees for registration or rescheduling may apply.
What is CVSS and why is it heavily tested on CySA+?
CVSS (Common Vulnerability Scoring System) is a standardized framework for rating vulnerability severity from 0.0 to 10.0. CySA+ tests CVSS because vulnerability prioritization is a core analyst skill, not all vulnerabilities are equal, and security teams must triage based on Base Score (exploitability, impact), Temporal Score (exploit maturity, remediation status), and Environmental Score (organizational context). CRITICAL (9.0–10.0), HIGH (7.0–8.9), MEDIUM (4.0–6.9), LOW (0.1–3.9).
What tools does CySA+ expect you to know?
CySA+ covers common security operations tools: vulnerability scanners (Nessus, Qualys, OpenVAS), SIEM platforms (Splunk, Microsoft Sentinel), threat intelligence platforms (MISP), network analysis (Wireshark, tcpdump), digital forensics (Autopsy, FTK), endpoint detection and response (EDR), and packet analysis. The exam tests tool selection and output interpretation rather than specific command syntax.
Is CySA+ harder than Security+?
Yes, CySA+ is harder than Security+. It requires deeper analytical thinking with scenario-based questions where you must analyze logs, network captures, and vulnerability scan output to identify threats and recommend responses. CompTIA recommends at least 4 years of hands-on security experience before taking CySA+. The 165-minute time limit (vs 90 minutes for Security+) reflects the added complexity.
What comes after CySA+ in the CompTIA path?
After CySA+, the CompTIA cybersecurity path continues with PenTest+ (penetration testing focus) or SecurityX/CASP+ (advanced practitioner). For management paths, CISSP (ISC2) or CISM (ISACA) are the next steps. Many CySA+ holders also pursue vendor-specific SOC certifications like Microsoft SC-200 (Security Operations Analyst) or Splunk certifications.
How difficult is the CompTIA CySA+ exam?
CompTIA CySA+ (CS0-003) is considered intermediate to advanced in difficulty, positioned between Security+ and SecurityX in the CompTIA path. The exam focuses on threat detection, analysis, and response using behavioral analytics and security tools. Most candidates with 3–4 years of security experience pass with 2–3 months of focused preparation.
What are the eligibility requirements for CompTIA CySA+?
There are no mandatory prerequisites. CompTIA recommends Network+ and Security+ certifications plus 3–4 years of hands-on information security experience before attempting CySA+. The credential is designed for security analysts who monitor, detect, and respond to threats.
How long should I study for CompTIA CySA+?
Most candidates prepare for 2–3 months using study guides, video courses, and extensive practice on log analysis, threat intelligence, vulnerability management, and incident response concepts. Mike Chapple and Jason Dion resources are widely used for CySA+ preparation.
What career value does CompTIA CySA+ provide?
CySA+ is valued for SOC analyst, cybersecurity analyst, and threat intelligence roles. It is DoD 8570 CSSP Analyst approved and is recognized in many government and defense contractor environments. Salaries for CySA+-credentialed analysts typically range from $65,000 to $95,000.
What is the CompTIA CySA+ retake policy?
No waiting period for the first retake; a 14-day wait applies after a second failure and all subsequent attempts. CompTIA's standard retake policy applies across all certification exams.
How long is CompTIA CySA+ valid?
CySA+ is valid for three years. It renews through the CompTIA CE program and automatically renews lower-level credentials (Security+) held during the same period.
What continuing education is required for CompTIA CySA+ renewal?
Renewal requires 60 CEUs over three years. Earning CompTIA SecurityX or PenTest+ during the CySA+ validity window also satisfies CySA+ renewal as part of CompTIA's stacked certification CE model.
How does CompTIA CySA+ compare to CompTIA PenTest+?
CySA+ is a blue-team (defensive) credential focused on monitoring networks, detecting threats, analyzing vulnerabilities, and responding to incidents. PenTest+ is a red-team (offensive) credential covering penetration testing planning, scoping, and exploitation techniques. Both sit at a similar level in the CompTIA path and address complementary sides of cybersecurity operations. Many security professionals pursue both for a full-spectrum perspective.
