CompTIA CySA+ Exam Preparation Checklist

You have done the studying — or most of it — and the question now is blunt: are you actually ready to sit the CompTIA Cybersecurity Analyst (CySA+) exam? This page is not another study plan. It is a readiness audit: a set of tick-boxes covering version and logistics decisions, domain-by-domain knowledge sign-offs, hands-on skill verification and a final-week countdown. Work through it honestly, and every unticked box tells you exactly what to fix before you spend an exam voucher.

Use it in two passes. Pass one, about a month out, identifies gaps while there is still time to close them. Pass two, in the final week, should be nearly all ticks — anything still open becomes your last-days revision list.

If you find whole sections unticked on the first pass, you need a study plan rather than a checklist — start with the full CySA+ exam preparation guide and come back here once coverage is behind you.

Section 1 — Version and booking checks

The administrative layer sinks more candidates than it should, especially in 2026 when two exam versions are live at once.

• [ ] I know which exam version I am sitting. As of August 2026, CS0-003 and CS0-004 are both bookable. CS0-004 launched on 23 June 2026 (English only at launch); the English CS0-003 exam retires on 22 December 2026, with translated CS0-003 exams available until 23 March 2027.
• [ ] If I chose CS0-003, my date maths works. My booked (or planned) exam date sits far enough before 22 December 2026 to leave room for a retake. CompTIA permits an immediate second attempt, but a third attempt requires a 14-day wait — and each attempt needs its own voucher.
• [ ] My study materials match my exam code. Every book, course and question set I am using names my version explicitly. (CompTIA's English CS0-003 learning products retire on 22 November 2026, so late-cycle CS0-003 candidates should not count on buying official materials at the last minute.)
• [ ] I have downloaded my version's official objectives from comptia.org and am auditing against that document, not a summary or an older version's outline.
• [ ] Budget confirmed. I have checked the current exam fee for my country on comptia.org (US retail as listed by CompTIA's authorised resellers in June 2026 was $439; authorised-reseller vouchers can be cheaper).
• [ ] Delivery mode chosen. Test centre, or online via Pearson VUE's OnVUE proctoring — and if online, I have verified my webcam, my ID documents and a private, interruption-free room.

Section 2 — Domain knowledge sign-offs

Tick a box only if you could explain the topic aloud to a junior colleague without notes. The domain structure below follows the current CS0-004 outline — Security Operations, Vulnerability Management, Incident Response and Management, and Reporting and Communication; CS0-003 candidates should audit against their own objectives document line by line, as the versions organise content differently.

Security operations

On CS0-004 this is the heavyweight domain at 34% of the exam — weight your remaining revision accordingly.

• [ ] I can read SIEM output and explain what a given correlation or alert is telling me.
• [ ] I can interpret log excerpts (authentication logs, web server logs, firewall logs) and pick out the anomalous entries.
• [ ] I can explain common attack techniques and the indicators each leaves behind.
• [ ] I can describe how threat intelligence feeds into day-to-day monitoring and triage decisions.
• [ ] Given tool output I have never seen before, I have a method: identify the tool class, orient on timestamps and sources, then look for the outlier.

Vulnerability management

• [ ] I can walk through a vulnerability management cycle from discovery to verification of remediation.
• [ ] I can read a scanner report and prioritise findings, explaining why one finding outranks another rather than sorting by raw severity score alone.
• [ ] I can explain the difference between scanning approaches and when each is appropriate.
• [ ] I can discuss handling of false positives and of findings that cannot be remediated immediately (compensating controls, risk acceptance, exceptions).

Incident response and management

• [ ] I can recite the incident response lifecycle in order and explain what belongs in each phase — and I answer process-order questions by that sequence, not by instinct.
• [ ] Given a scenario, I can identify the correct next step — the exam's favourite framing.
• [ ] I can distinguish an event from an incident and explain who declares which.
• [ ] I can describe containment choices for a compromised host and the trade-offs between them.

Reporting and communication

The smallest CS0-004 domain at 16% — and the one experienced technical candidates most often leave unstudied.

• [ ] I can name what belongs in a vulnerability report versus an incident report.
• [ ] I can match the audience to the message: what the executive summary carries versus what the technical appendix carries.
• [ ] I can explain common security metrics and why an organisation tracks them.
• [ ] I know the escalation and notification obligations a scenario might invoke, and who gets told when.

Section 3 — Hands-on skill verification

CySA+ includes performance-based questions, and reading about tools does not survive contact with them. Each box is a task actually performed, not a video watched.

• [ ] I have run queries against a SIEM or log platform and filtered a noisy dataset down to the events that matter.
• [ ] I have run a vulnerability scan against a lab target and read the full report, not the dashboard summary.
• [ ] I have examined a packet capture and narrated the conversation it records.
• [ ] I have used core command-line tools on both Linux and Windows to inspect processes, connections and files.
• [ ] I have rehearsed one full scenario end to end — alert, triage, validation, escalation decision, containment, closing report — because a single narrated run-through of that chain touches every exam domain at once.
