Exam Overview
The CrowdStrike Certified SIEM Analyst (CCSA-205) is an associate-level certification that validates a security professional's ability to investigate detections and analyze data within the CrowdStrike Falcon Next-Gen SIEM environment. The credential tests hands-on competency across four core operational areas: constructing and executing queries using CrowdStrike Query Language (CQL), evaluating detection logic and alert metadata, reconstructing incident timelines, and communicating findings through Case Management and visual reporting tools.
Offered through CrowdStrike University and administered via Pearson VUE, the CCSA-205 is purpose-built for practitioners who work—or plan to work—directly inside the Falcon platform. It covers platform-specific capabilities including the CrowdStrike Parsing Standard, cross-dataset correlation, MITRE ATT&CK framework mapping, and Falcon Fusion SOAR workflow integration, making it directly applicable to day-to-day SOC operations rather than theoretical security knowledge.
Who Should Take This Exam
The CCSA-205 is designed for SOC analysts, threat hunters, incident responders, and security engineers who use or are adopting CrowdStrike Falcon Next-Gen SIEM in their organizations. It is particularly well-suited for Tier 1 and Tier 2 analysts who triage alerts, investigate detections, and escalate incidents, as well as detection engineers responsible for building and tuning correlation rules.
Candidates should have foundational familiarity with core security operations concepts and log analysis workflows. Those transitioning into a CrowdStrike-centric environment from other SIEM platforms will find the exam validates their ability to apply existing SOC skills within the Falcon ecosystem specifically.
Prerequisites
There are no formal prerequisites published for the CCSA-205, but CrowdStrike recommends that candidates possess prior hands-on SIEM experience and comfort with log analysis before attempting the exam. Familiarity with security operations fundamentals—such as alert triage, event correlation, and incident scoping—is assumed by the exam objectives.
Candidates without previous SIEM platform experience should plan additional time for lab practice within the Falcon Next-Gen SIEM environment. Completing the CrowdStrike University training curriculum aligned to the CCSA is strongly recommended as the primary preparation path, as the exam tests platform-specific workflows and tooling rather than vendor-agnostic concepts.
Exam Format
The CCSA-205 consists of 60 scored questions delivered over a 90-minute time limit, requiring a passing score of 80%. The exam is administered through Pearson VUE and can be taken either at a Pearson test center or via the OnVUE online proctoring platform, which allows candidates to test remotely under live proctoring conditions.
The exam fee is $250 USD. CrowdStrike University policy permits up to four attempts for candidates who do not pass on the first try. Questions are drawn from the four official knowledge domains and are designed to assess practical, scenario-based competency with the Falcon platform rather than purely theoretical recall.
Skills Measured
- 1.Querying and Analytics: Constructing CQL (CrowdStrike Query Language) searches using filters, logical operators, and time parameters; leveraging Falcon dashboards; applying the CrowdStrike Parsing Standard; and performing cross-dataset correlations to surface meaningful patterns across multiple log sources.
- 2.Detection Logic and Alert Analysis: Understanding how correlation rules are structured and triggered; distinguishing between detection types within Falcon Next-Gen SIEM; mapping alerts to MITRE ATT&CK tactics, techniques, and procedures; and evaluating alert metadata including severity, confidence scores, and tactic classifications to perform false-positive triage.
- 3.Incident Investigation: Reconstructing end-to-end event chains; identifying indicators of lateral movement and persistence within telemetry; interpreting IOCs (indicators of compromise); pivoting between observables across datasets; scoping incident severity; and leveraging Falcon Fusion SOAR workflows to initiate or automate response actions.
- 4.Reporting and Communication: Documenting investigation findings and evidence using Falcon Case Management; creating aggregated data views and visual summaries; and communicating analytical conclusions to technical and non-technical stakeholders in a clear and defensible manner.
Study Tips
- Download and work through the official CrowdStrike University CCSA Certification Exam Guide (available at crowdstrike.com/en-us/crowdstrike-university/crowdstrike-falcon-certification-program/) as the primary reference — it defines the exact domains, objectives, and recommended preparation resources for the exam.
- Build hands-on proficiency with CrowdStrike Query Language (CQL) by practicing searches in a live or trial Falcon Next-Gen SIEM environment. Focus on constructing queries with filters, logical operators, time ranges, and aggregations, as the Querying and Analytics domain is central to the exam.
- Study the MITRE ATT&CK framework specifically in the context of Falcon's detection metadata. Practice mapping real alerts to ATT&CK tactics and techniques, since the Detection Logic domain tests your ability to interpret how Falcon classifies and surfaces threat activity.
- Practice building complete incident timelines using Falcon's investigation tools. Work through sample scenarios that require pivoting between different data sources, identifying lateral movement patterns, and scoping severity — skills tested directly in the Incident Investigation domain.
- Complete the CrowdStrike University training courses aligned to the CCSA before scheduling the exam. These courses are designed around the same four domains assessed and include platform-specific walkthroughs of Falcon Next-Gen SIEM, Falcon Fusion SOAR, and Case Management workflows.
- Use a structured four-week study plan, dedicating one week to each of the four exam domains. Within each week, alternate between reviewing documentation, practicing CQL queries or detection scenarios, and reviewing any available sample questions to reinforce retention.
- Familiarize yourself with Falcon Fusion SOAR capabilities and how they integrate with SIEM investigations. Understanding how playbooks and automated workflows function within Falcon will prepare you for incident-response scenario questions and reinforces the practical, platform-specific depth the exam demands.
Career Benefits
The CCSA-205 credential signals to employers that a candidate can operate autonomously within the CrowdStrike Falcon platform — converting raw telemetry into actionable security decisions under realistic SOC conditions. As enterprise adoption of CrowdStrike's Next-Gen SIEM continues to grow, platform-specific certifications like the CCSA carry increasing weight in hiring decisions for SOC analyst, detection engineer, and incident responder roles at organizations standardized on the Falcon ecosystem.
The certification strengthens candidates' positioning for Tier 1 through Tier 3 SOC roles, threat hunting positions, and security engineering roles focused on detection development. While vendor-neutral credentials such as CompTIA CySA+ or GIAC GCIH remain relevant for foundational credentialing, the CCSA differentiates candidates specifically for CrowdStrike-centric environments and complements broader certifications by demonstrating platform depth. It also serves as a foundation for pursuing higher-level CrowdStrike certifications in the Falcon program.

Preview — answers shown1. A SOC analyst at Horizon Defense is building a dashboard panel to visualize authentication failure events over time in 15-minute intervals across a 24-hour period. The analyst needs the query output formatted as a time-series suitable for a line chart. Which CQL function should the analyst use? (Select one!)
AgroupBy()
Btimechart()
Ccount()
Dbucket()
Explanation
timechart() is specifically designed for time-bucketed aggregation, producing output formatted for time-series chart visualizations in dashboard panels. It automatically groups events into equal time intervals and produces structured results that map directly to line charts and bar charts. groupBy() can group events by field values but does not produce time-bucketed output aligned to equal intervals for time-series charting purposes. count() is a simple aggregation function that returns a single total count value rather than a time-series breakdown. bucket() groups continuous numeric values into discrete range bins and is not designed for temporal visualization of event frequency over time.
2. A threat analyst at Keystone Analytics needs to compute a ratio between two numeric fields — BytesSent and BytesReceived — and attach the result as a new field named DataRatio to each event in the pipeline for use in downstream filtering. Which CQL function should the analyst use to create this calculated field? (Select one!)
Atimechart()
Beval()
CgroupBy()
Dselect()
Explanation
The eval() function is the correct CQL tool for creating calculated fields by applying mathematical operations, string transformations, or conditional logic to existing field values. When the analyst writes eval(DataRatio := BytesSent / BytesReceived), the function attaches the computed result as a new field named DataRatio to every event passing through that pipeline stage. Downstream filters or aggregations can then reference DataRatio as if it were an original event field. The groupBy() function collapses events into aggregate rows and cannot create per-event calculated fields. The select() function controls which existing fields are retained or renamed in the output but cannot compute new values derived from field arithmetic. The timechart() function produces time-series visualizations and does not generate calculated event-level fields.
3. A threat analyst at Clearwater Analytics needs to write a CQL query that shows how the frequency of NetworkConnectIP4 events changes across equal time intervals, producing output structured for a trend chart that plots event counts against time buckets. Which CQL function is designed specifically for this purpose? (Select one!)
Asankey()
Btimechart()
CgroupBy()
Deval()
Explanation
The timechart() function produces a time-series aggregation that automatically groups event counts — or other computed metrics — into time buckets and returns output structured for temporal visualization. When applied to NetworkConnectIP4 events, timechart() plots event frequency across the selected time window, enabling analysts to identify spikes, anomalies, or recurring patterns in network activity over time. The groupBy() function aggregates events by one or more field values but does not inherently create time-interval buckets for trend visualization; it produces a flat aggregate table rather than a time-series chart. The eval() function creates calculated fields on individual events and is not an aggregation or visualization function. The sankey() function maps directional flows between source and destination entities — useful for visualizing network traffic paths between hosts — but does not produce time-series frequency charts.
4. A SOC analyst at Helios Security is building a CQL query to calculate the ratio of failed authentication attempts to total authentication events per host, then display only hosts where the failure rate exceeds 80%. Which CQL function should the analyst use to create this calculated ratio field within the query pipeline? (Select one!)
Acase()
BgroupBy()
Ceval()
Dbucket()
Explanation
eval() creates new calculated fields within a CQL pipeline by performing mathematical operations or logical transformations on existing event fields. In this scenario, the analyst would use eval() to compute the failure rate as a ratio of failed to total authentication events, producing a derived field that can then be filtered against the 80% threshold. groupBy() aggregates events by specified dimensions but does not create calculated ratio fields from other fields. bucket() groups numeric values into predefined ranges but does not perform ratio calculations between separate fields. case() provides conditional branching logic designed for value mapping and classification rather than mathematical field computation between event attributes.
5. A detection analyst at Irongate Security needs to enrich a CQL pipeline with a new field that calculates the ratio of failed authentication attempts to total authentication attempts per host, so the derived metric can be used for downstream threshold alerting. Which CQL function should they use to create this derived calculated field? (Select one!)
Aeval()
BgroupBy()
Cselect()
Dbucket()
Explanation
The eval() function creates calculated fields within a CQL pipeline by evaluating mathematical expressions or logical operations against existing fields. This makes it the correct choice for computing a ratio between two numeric values — such as failed authentications divided by total authentications — and assigning the result to a new named field that downstream stages can reference for threshold comparisons or visualizations. The groupBy() function aggregates events by field values and produces count or summary statistics, but does not create derived ratio fields. The bucket() function segments continuous numeric values into discrete analyst-defined ranges for histogram-style distribution analysis. The select() function controls which fields are included in the query output but cannot perform arithmetic calculations or create new derived fields.
