CompTIA CySA+ (CS0-004) is a defensive cybersecurity analyst certification. It tests whether you can take the evidence in front of you, a log line, a scan result, a packet capture, an alert, and decide what an analyst does next: triage it, interpret what it proves, prioritise it against everything else, and escalate or contain it at the right point in the incident response lifecycle. The best answer is almost never an architect's redesign or a penetration tester's exploit. It is the measured next action of someone defending a live environment.
CS0-004 is the current version. It launched on 23 June 2026 and replaces CS0-003. The English-language CS0-003 exam retires on 22 December 2026. If you are booking now, study V4, not V3: any effort spent on the outgoing version is effort you cannot use after that date, and the V4 objectives add material V3 does not cover, most visibly the use of artificial intelligence in security operations.
The certification suits working or aspiring security operations centre analysts, threat hunters, incident responders, and vulnerability management staff. It sits above Security+ in depth and leans hard on analysis rather than recall. Questions are scenario-led and include performance-based tasks, so the skill being measured is judgement under incomplete information: given what this data source can and cannot prove, what is the correct call.
The exam rewards the analyst mindset over the tool list. Knowing that a SIEM correlates or that EDR watches endpoints is the easy half. The marks are in reasoning about what a detection source actually demonstrates, whether an alert is a true positive or a false positive, how urgent a vulnerability really is once exploitability and asset value are weighed, and how to report the finding to the audience that needs it.
CS0-004 rewards what a defender does with the evidence in front of them, triage, interpret, prioritise, contain, report, not how to design the system or exploit it.

How this exam thinks
Three habits separate a pass from a fail on CS0-004, and each is about behaving like an analyst rather than knowing one more fact.
First, the exam wants the next action, not the best design. Many options are true statements a competent engineer might say, but the question is set at the analyst's desk during an event. If a distractor rebuilds the network segmentation or writes an exploit, it is answering a different job. Read the scenario for the analyst's immediate responsibility: what does the evidence justify doing right now, and at which incident response phase. When two options both look reasonable, prefer the one that matches the phase the scenario is in. Containment comes before eradication, and eradication before recovery, so an answer that eradicates before the threat is contained is out of order even when the action itself is correct.
Second, the exam treats prioritisation as more than a CVSS number. A raw base score is a starting point, not the answer. The urgency of a vulnerability depends on whether it is actually exploitable in this environment, whether threat intelligence shows it being used in the wild, how critical the affected asset is to the business, and whether a compensating control already blunts it. A high CVSS on an isolated system with no reachable path can rank below a medium score on an internet-facing crown-jewel asset. When a question asks what to fix first, look past the number to exploitability, exposure, asset value, and business context.
Third, the exam expects you to reason about what a detection source can prove. Each source has a blind spot. Packet capture shows content but not if traffic is encrypted; NetFlow shows who talked to whom and how much but not what was said; DNS logs reveal resolution and beaconing patterns but not payloads; email headers can expose spoofing and routing but are themselves forgeable; EDR sees endpoint behaviour but not what never reached an instrumented host. Match the question to the source that could actually demonstrate the claim, and distrust an answer that asks a source to prove something outside its reach. The same discipline separates a true positive from a false positive: confirm with a second source before you act on one.
What each domain tests and how to study it
The CS0-004 blueprint is split across 4 domains. Weights are the official share of the exam; see the official exam guide for the authoritative breakdown.
What you must be able to do. Read system and network telemetry like an analyst: know what each detection source can and cannot prove, tell malicious activity from benign, apply threat intelligence and hunting, and use process improvement, SOAR, and AI to work efficiently.
In one sentenceThe daily work of a SOC analyst: understanding the monitored architecture and its logs, analysing indicators of malicious activity, choosing the right tool for the evidence, applying threat intelligence and hunting, and improving efficiency with process, SOAR, and AI.
Recall check: answer these from memory first
For SIEM, EDR, packet capture, NetFlow, DNS logs, and email headers, say in one line each what the source can prove and what it cannot.
Give the one-line distinction between threat intelligence and threat hunting, and say which one starts from a hypothesis.
Name two ways AI helps a SOC analyst and the one reason its output must still be verified before you act on it.
What it tests. How security operations actually run: the system and network architecture that generates telemetry, including logging, and how to analyse indicators of potentially malicious activity across hosts, networks, and applications. It tests which tool or data source determines malicious activity, how threat intelligence and threat hunting inform detection, and how to improve efficiency and process through automation, orchestration, and SOAR. This version also tests the use of artificial intelligence in security operations, both as a capability and as something to reason about critically.
How to study it. Anchor every source to what it can prove and what it cannot, because that is the exam's favourite hinge. Build a mental table: SIEM correlates and alerts across sources, EDR watches endpoint behaviour, packet capture shows content unless encrypted, NetFlow shows conversations and volume without content, DNS logs surface beaconing, email headers expose spoofing and routing. Practise reading a log excerpt and stating in one line what it demonstrates and what it does not. For the AI material, learn both the uses, triage assistance, correlation, summarising alerts, and the caution: AI output is a lead to verify, not a verdict.
Easy to confuse
NetFlow versus full packet capture. NetFlow records the metadata of a conversation, source, destination, ports, bytes, timing, but never the content; full packet capture records the actual payload, subject to encryption. If the question needs to know who talked to whom and how much, NetFlow suffices; if it needs what was said, only packet capture can show it, and only if the traffic was not encrypted.
Threat intelligence versus threat hunting. Threat intelligence is curated knowledge about adversaries, indicators, and tactics that you consume; threat hunting is the proactive search through your own telemetry for a threat that no alert has flagged, usually starting from a hypothesis. Intelligence feeds the hunt; the hunt is the activity.
SIEM versus SOAR. A SIEM collects, correlates, and alerts on log data so an analyst can see what happened; SOAR takes those findings and orchestrates and automates the response through playbooks. If the scenario is about seeing and correlating, it is SIEM; if it is about automating the reaction to reduce manual effort, it is SOAR.

A SOC deploys an AI assistant that summarises and prioritises incoming alerts to speed up triage. During a busy shift, an analyst notices the assistant consistently ranks alerts from one noisy scanner as top priority while burying a credential-stuffing pattern lower down. What is the analyst's best response?
AApply analyst judgement to re-prioritise the credential-stuffing alerts and report the ranking flaw for tuning.check_circle Correct
BDisable all AI triage assistance permanently, as it has proven unable to prioritise alerts correctly.
CContinue to accept the assistant's ranking, since the tool processes more context than a human analyst can.
DDelete the noisy scanner alerts from the queue so the assistant stops ranking them highly.
AI triage augments rather than replaces analyst judgement, so analysts override flawed prioritisation and feed corrections back for tuning. Alert triage augmentation is designed to assist human decisions, not overrule them, so when the tool mis-ranks a genuine threat the analyst reprioritises on the evidence and reports the flaw so the model can be tuned.
Why A is correct: Correct: AI triage augments the analyst, so the analyst overrides the flawed ranking on the evidence and feeds the issue back so the tool improves.
Why B is wrong: Tempting after a visible miss, but a single prioritisation error does not justify removing a tool that reduces overall triage load; the fix is oversight, not abandonment.
Why C is wrong: Tempting because AI can weigh more signals, but blind acceptance of a demonstrably skewed ranking lets a real threat sit unactioned.
Why D is wrong: Tempting as a quick way to clean the queue, but deleting source alerts destroys evidence and does not address the assistant's flawed weighting.
What you must be able to do. Run and read vulnerability scans, interpret tool output including false positives, and prioritise remediation by exploitability, threat intelligence, asset criticality, compensating controls, and business context rather than raw CVSS alone.
In one sentenceFinding weaknesses and deciding what to do about them: implementing scanning correctly, analysing scan and tool output, prioritising by real-world risk rather than raw score, and choosing the right control or mitigation.
Recall check: answer these from memory first
List five factors beyond the CVSS base score that change how urgently a vulnerability should be remediated.
Say how a credentialed scan differs from a non-credentialed one and what each is better at finding.
Describe how you would confirm whether a scanner finding is a false positive before acting on it.
What it tests. How vulnerability management is implemented and acted on: configuring and running scans appropriately, including credentialed versus non-credentialed and where in the environment to scan, and analysing the output of scanners and related tools while separating genuine findings from false positives. It tests prioritising and mitigating vulnerabilities using more than the CVSS base score, weighing exploitability, threat intelligence, asset criticality, compensating controls, and business context, and understanding control types and the risks that different responses carry.
How to study it. Practise turning a scan report into a ranked action list, because that is the exam's core task here. For any two findings, be able to argue which to fix first using exploitability, whether the flaw is being exploited in the wild, how critical the asset is, and whether a compensating control already reduces the exposure. Treat CVSS as the opening line, not the verdict. Learn to recognise a false positive from scan output and to say how you would confirm it before raising or dismissing it. Know the control categories and that accepting, transferring, mitigating, or avoiding a risk are all valid depending on business context.
Easy to confuse
CVSS base score versus real-world priority. The CVSS base score measures the inherent severity of a flaw in isolation; real-world priority weighs that against exploitability in this environment, active exploitation in threat intelligence, asset criticality, and existing compensating controls. A high base score on an unreachable asset can rank below a medium score on an exposed critical system.
Credentialed versus non-credentialed scan. A credentialed scan logs in with valid access and sees installed software, patch levels, and configuration from the inside, producing fewer false positives; a non-credentialed scan probes from outside and sees only what an unauthenticated attacker would. The exam pairs the depth of information needed with the scan type.
Compensating control versus remediation. Remediation removes the vulnerability itself, by patching or reconfiguring; a compensating control leaves the flaw in place but reduces the risk it poses, for example network isolation or tighter monitoring. When a fix cannot be applied immediately, a compensating control lowers priority without closing the finding.

Within the CVSS version 3.1 framework, what does the Environmental metric group allow an analyst to do that the Base metric group alone cannot?
AAdjust the score to reflect the security requirements and modified characteristics of the analyst's own deployment.check_circle Correct
BReflect the current maturity of available exploit code and the state of official remediation.
CExpress the intrinsic severity of the flaw independent of any particular organisation or time.
DPredict the probability that the vulnerability will be exploited in the wild within thirty days.
Distinguish the CVSS Environmental metric group as the mechanism for tailoring a base score to local asset context and security requirements. The Environmental group applies modified base metrics and confidentiality, integrity and availability requirement weightings so the final score represents risk to the specific environment rather than the flaw in the abstract.
Why A is correct: Correct: the Environmental group re-weights confidentiality, integrity and availability requirements and lets the analyst override base metrics to match how the asset is actually deployed.
Why B is wrong: Tempting because these do adjust a score over time, but exploit maturity and remediation level belong to the Temporal metric group, not the Environmental group.
Why C is wrong: This describes the purpose of the Base metric group itself, which is the fixed starting point the Environmental group is meant to tailor.
Why D is wrong: Exploitation probability is what EPSS estimates; CVSS environmental scoring measures contextual impact, not likelihood of attack over a time window.
What you must be able to do. Apply attack frameworks such as MITRE ATT&CK, the Cyber Kill Chain, and the Diamond Model to interpret activity, and move through the incident response lifecycle in the correct order when implementing response techniques.
In one sentenceHandling incidents by the book: using attack methodology frameworks to make sense of adversary behaviour, following the incident response lifecycle in order, and implementing the right technique at the right phase.
Recall check: answer these from memory first
State the incident response lifecycle phases in order and give the one-line reason containment comes before eradication.
Say in one line what MITRE ATT&CK, the Cyber Kill Chain, and the Diamond Model each describe.
Give an example of an eradication action and an example of a recovery action, and say why the order matters.
What it tests. Understanding attack methodology frameworks and using them to interpret observed activity: MITRE ATT&CK for mapping adversary tactics and techniques, the Cyber Kill Chain for the stages of an intrusion, and the Diamond Model for relating adversary, capability, infrastructure, and victim. It tests the incident response process and lifecycle, preparation, detection and analysis, containment, eradication, recovery, and lessons learned, and how to implement incident response techniques correctly, including doing the right thing at the right phase and in the right order.
How to study it. Fix the lifecycle order in memory and rehearse it against scenarios, because the exam plants out-of-order actions as distractors. Contain before you eradicate; eradicate before you recover; capture lessons learned at the end so the next incident is handled better. For the frameworks, learn what each is for rather than memorising every entry: ATT&CK catalogues how adversaries behave, the Kill Chain describes the sequence of an intrusion, the Diamond Model relates the four core features of an event. Practise placing a described action at its correct phase, and spotting when an option is right in general but premature for the phase the scenario is in.
Easy to confuse
Containment versus eradication. Containment limits the damage and stops the incident spreading, for example isolating a host, while the threat may still be present; eradication removes the threat itself, for example deleting malware and closing the entry point. Containment is always first, because eradicating before you have contained lets the threat move while you work.
Eradication versus recovery. Eradication removes the adversary and the cause; recovery restores systems to normal operation and confirms they are clean before returning them to service. Recovering a system that has not been fully eradicated reintroduces the compromise, so recovery only follows a confirmed eradication.
MITRE ATT&CK versus the Cyber Kill Chain. ATT&CK is a detailed matrix of adversary tactics and the techniques under each, used to map observed behaviour; the Cyber Kill Chain is a linear model of the stages of an intrusion from reconnaissance to actions on objectives. Use ATT&CK to classify what was seen; use the Kill Chain to reason about where in the intrusion the activity sits.

lock_openFree sampleIncident Response and Managementmedium
During triage you review an EDR alert on a finance workstation: 'rundll32.exe loaded a signed but unusual DLL from C:\Users\Public, then spawned a connection to a known content delivery domain'. Your team maps every observation to MITRE ATT&CK. Which mapping BEST fits the rundll32 behaviour observed here?
AInitial Access via T1566 Phishing, because the workstation belongs to a finance user who is a common phishing target
BExfiltration via T1041 Exfiltration Over C2 Channel, because a network connection to an external domain was observed
CDefense Evasion via T1218 System Binary Proxy Execution, because a trusted signed Windows binary is being abused to run the payloadcheck_circle Correct
DPersistence via T1547 Boot or Logon Autostart Execution, because the DLL was loaded from a public writable folder
Map abuse of a trusted signed system binary to the correct ATT&CK technique rather than to an unproven adjacent tactic. System binary proxy execution abuses a signed, allowlisted OS binary such as rundll32 to run attacker code, which evades controls that trust the parent process; the observed load-and-execute chain matches this technique rather than delivery, exfiltration, or persistence.
Why A is wrong: Tempting because finance users are phished often, but the evidence shows post-execution binary abuse, not a delivery vector, so mapping to phishing invents a tactic the artefact does not establish.
Why B is wrong: Tempting because an outbound connection is present, but a single connection to a CDN domain is not evidence that data left the host, so keying exfiltration overreads the artefact.
Why C is correct: Correct: rundll32 is a legitimate signed system binary abused to proxy execution of an attacker DLL, which is exactly the living-off-the-land pattern ATT&CK catalogues under T1218.
Why D is wrong: Tempting because a writable path suggests staging, but nothing shows a run key, service, or startup entry, so persistence is a technique the evidence does not support.
What you must be able to do. Report vulnerability and incident findings so the audience can act on them: the right metrics and KPIs for the reader, a clear root-cause narrative, and communication pitched to the stakeholder rather than to another analyst.
In one sentenceTurning findings into action through communication: vulnerability management reporting, incident response reporting, and pitching each to the stakeholder who has to act on it.
Recall check: answer these from memory first
Name three metrics or KPIs a vulnerability management report would track and say what each one tells the reader.
List the parts of an incident response report and say which one prevents the incident recurring.
For an executive, a technical team, and a regulator, say in one line what each most needs from the same finding.
What it tests. How analysts report and communicate: vulnerability management reporting with the metrics and KPIs that show progress and risk, incident response reporting that captures what happened, the impact, the root cause, and the lessons learned, and stakeholder communication that adjusts detail and language to the audience. It tests recognising which metric or level of detail suits an executive, a technical team, or a regulator, and that a report which the reader cannot act on has failed regardless of how accurate it is.
How to study it. Treat communication as a skill the exam scores, not a soft afterthought. Learn to match the message to the audience: an executive wants risk, business impact, and trend, not raw scan lines; a technical team wants the specifics to fix; a regulator wants compliance and timeline. Learn the common vulnerability management metrics and KPIs and what each one signals, and be able to structure an incident report around impact, root cause, and lessons learned. Practise picking the appropriate metric or detail level for a stated recipient, which is how this domain is usually tested.
Easy to confuse
Executive reporting versus technical reporting. An executive report communicates business risk, impact, and trend to support a decision and rarely needs raw technical detail; a technical report gives the specifics an engineer needs to reproduce and fix the issue. The exam pairs the audience with the appropriate level of detail, and the wrong answer gives the executive the engineer's report.
Root cause versus impact. The impact is what the incident did, systems affected, data exposed, downtime; the root cause is why it was possible, the underlying weakness that let it happen. A report that states impact without root cause cannot prevent recurrence, which is why the lessons-learned step depends on naming the root cause.

lock_openFree sampleReporting and Communicationmedium
During a ransomware incident, your executive sponsor sends this email at 09:15: "Board call at 10:00. Give me the current business impact and what we are doing, in plain terms." You have technical findings but the eradication is still in progress. What should your update to the sponsor prioritise?
AWhich services are down, the current containment status, and the expected next milestone in plain business languagecheck_circle Correct
BA packet-level breakdown of the C2 beacon intervals and the malware's registry persistence keys
CA request that the board approve purchasing a new EDR platform before the call begins
DThe full indicator-of-compromise list so the board can forward it to peer organisations
Tailor incident communications to the audience: executives need business impact, status, and next steps in plain language, not raw technical artefacts. Stakeholder communication effectiveness depends on matching content to the audience's decisions. Executives make resourcing and disclosure calls, so they need impact, containment status, and milestones framed in business terms rather than low-level indicators they cannot use.
Why A is correct: An executive update should translate technical status into business impact and next steps, matching the audience and the decision they must support.
Why B is wrong: This is accurate technical detail, but a board-facing sponsor needs business impact and status, not indicators they cannot act on.
Why C is wrong: Procurement decisions belong in the lessons-learned phase, not a mid-incident status update, and pre-empting them derails the sponsor's immediate need.
Why D is wrong: Sharing raw IOCs with a board is the wrong audience and risks premature disclosure; the sponsor asked for impact and actions in plain terms.
A study plan that works
Confirm you are studying V4 and set a date
Day 1
CS0-004 is the current exam and CS0-003 retires on 22 December 2026, so make sure your materials are V4. Read the official exam objectives and the four domains with their weights, then book a provisional date. A fixed date turns open-ended study into a plan and is the single biggest predictor of actually sitting the exam.
Build the security operations foundation
Weeks 1-2
Security operations is the largest domain and underpins the rest. Learn the monitored architecture and its logging, and build the source-by-source table of what each detection source can and cannot prove. Cover threat intelligence, threat hunting, SOAR, and the use of AI in the SOC. Practise reading log and telemetry excerpts and stating what they demonstrate.
Master vulnerability prioritisation, not just scanning
Weeks 2-3
Learn to run and read scans, then spend the bulk of your time on prioritisation. Drill ranking two findings using exploitability, threat intelligence, asset criticality, and compensating controls rather than the CVSS number alone. Practise spotting false positives and saying how you would confirm them.
Lock the incident response lifecycle order
Weeks 3-4
Commit the lifecycle phases to memory and rehearse them against scenarios: contain, then eradicate, then recover, then lessons learned. Learn what MITRE ATT&CK, the Cyber Kill Chain, and the Diamond Model are each for, and practise placing an action at its correct phase and spotting the premature-action distractor.
Practise reporting and stakeholder communication
Week 4
Cover vulnerability and incident reporting and the metrics and KPIs that belong in each. Practise pitching the same finding to an executive, a technical team, and a regulator. This domain is smaller but the questions are reliable marks once you match message to audience.
Drill scenarios and performance-based tasks
Week 5
Move to full practice sets, including performance-based questions, and read the explanation for every item, including those you got right. The exam tests analyst judgement between plausible options, so understanding why a distractor is the wrong next action is where the marks are.
Sit a timed mock, then close weak domains
Week 6
Take at least one full timed mock to rehearse pacing and the flag-and-return habit. Use your per-domain accuracy to drill the two weakest domains rather than re-reading what you already know, and repeat until every domain clears the pass line with margin on unseen questions.
Know when you're ready
Readiness for CS0-004 is a measured score on questions you have not seen before, not a feeling that the material is familiar. Those are different things, and the gap between them is where analysts fail. Re-reading notes builds fluency, and fluency feels like knowledge, so confidence rises while real recall does not. The fix is to test yourself on fresh scenarios: if you can name the correct next action and explain why each other option is the wrong move or the wrong phase, you know it; if you can only nod along to the explanation, you do not yet.
Because this is an analyst exam, judge yourself on judgement, not recall. It is not enough to know the six lifecycle phases; you have to place an action in the right one under time pressure, and rank vulnerabilities by real risk rather than raw score, and say what a data source can prove. Trust your per-domain accuracy on unseen questions over your gut, and set the bar at clearing every domain comfortably across more than one session, not scraping the pass mark once. The practice bank, with an explanation of why the right answer is right and every wrong one is wrong, is where you find out whether you can navigate the map this guide gives you.
Ready to put this into practice?
Free CS0-004 questions, every answer explained. No sign-up.
Read the last line of the question first. It tells you what the analyst is actually being asked to do, so you can read the scenario looking for the answer rather than memorising detail.
Choose the analyst's next action, not the architect's redesign or the pentester's exploit. Several options may be true; the exam wants the correct defensive move for the situation as written.
Check the incident response phase before you answer. Contain before eradicate, eradicate before recover; an action that is right in general is wrong if it is premature for the phase.
On prioritisation questions, look past the CVSS number to exploitability, active exploitation, asset criticality, and compensating controls. The highest score is not always the first fix.
Ask what the named data source can actually prove. If an option asks NetFlow to show content or email headers to prove intent, it is reaching beyond the source and is likely the distractor.
Flag and move on. Do not lose time on one hard item or performance-based task when easier marks are waiting; cover every question first, then return.
For reporting questions, match the message to the audience. The wrong answer usually hands an executive the engineer's detail or a regulator the wrong metric.
Frequently asked questions
Should I study CS0-004 or CS0-003?
Study CS0-004. It is the current version, launched on 23 June 2026, and CS0-003 retires for the English exam on 22 December 2026. If you are booking now, V4 is the exam you will sit, and it adds material V3 does not cover, including the use of artificial intelligence in security operations.
When did CS0-004 launch and when does CS0-003 retire?
CS0-004 launched on 23 June 2026 and is the current version. The English-language CS0-003 exam retires on 22 December 2026. After that date you should be studying and sitting V4, so new candidates should not start on the outgoing version.
Is CySA+ a defensive or an offensive certification?
It is defensive. CySA+ is a security analyst credential, so the best answer is almost always what an analyst does with the evidence: triage, interpret, prioritise, contain, and report. Options that redesign the architecture or exploit a target are answering a different job and are usually distractors.
Is CS0-004 hard?
It is an intermediate exam and harder than Security+, mostly because it tests analysis rather than recall and includes performance-based questions. The difficulty is in judgement: choosing the correct next action among plausible options, prioritising by real risk, and reasoning about what a data source can prove. Scenario practice that explains every option matters more than memorising definitions.
Do I need to know how to exploit systems to pass?
No. CySA+ is a blue-team analyst exam, not a penetration testing one. You need to recognise attacker techniques and frameworks such as MITRE ATT&CK well enough to interpret what you are seeing in your telemetry, but the tasks are detection, triage, response, and reporting, not exploitation.
How should I prioritise vulnerabilities if not by CVSS?
Use the CVSS base score as a starting point, then weigh exploitability in your environment, whether threat intelligence shows active exploitation, how critical the affected asset is, whether a compensating control already reduces the risk, and the business context. A high score on an unreachable asset can rank below a medium score on an exposed critical system.
What order do the incident response phases go in?
Preparation, detection and analysis, containment, eradication, recovery, then lessons learned. The order is load-bearing on the exam: contain before you eradicate so the threat cannot spread while you work, and eradicate before you recover so you do not restore a still-compromised system. Distractors often propose the right action at the wrong phase.
How long should I study for CS0-004?
Most candidates with some hands-on security experience are ready in roughly six weeks of focused study, more if the analyst workflow is new to you. Spend the most time on security operations and vulnerability prioritisation, which carry the most weight and the most judgement.
