Tier 1: Must KnowYou must understand these concepts deeply, know configurations, and be able to apply them in hands-on scenarios. These appear across multiple questions.
Tier 2: Should KnowUnderstand what these are and their key characteristics. May appear in 2-5 questions each.
Tier 3: Recognize OnlyKnow what these are at a high level. Rarely more than 1-2 questions each.
Domain 17% of exam

User Management

This domain covers configuring user roles, permissions, and establishing custom role structures for platform access control within Falcon Next-Gen SIEM. While the smallest domain by weight, it tests foundational knowledge that underpins all other SIEM operations.

Key Topics

RBACUser RolesCustom RolesPermissionsAccess Control

Must-Know Concepts

  • How to configure user roles and permissions within Falcon Next-Gen SIEM for appropriate access control
  • Role-based access control (RBAC) implementation for secure platform management and data access separation
  • Custom role creation to establish granular access structures tailored to organizational needs and security requirements
  • The relationship between user permissions and data visibility, including repository-level access controls
  • Administrative vs analyst vs read-only role distinctions and when to apply each level of access

Common Exam Traps

Custom roles must be explicitly created and assigned — there is no automatic role inheritance from organizational hierarchy
User permissions affect what data sources, dashboards, and SOAR workflows a user can access, not just login capability
Repository-level access controls are separate from platform-level role assignments — both must be configured correctly
Quick Check: User Management

Question 1 of 3

A security team needs to ensure that SOC Tier 1 analysts can view dashboards and run CQL queries but cannot modify correlation rules or SOAR workflows. Which approach should the administrator take?

Domain 227% of exam

Data Ingestion

The second-heaviest domain covering how data enters Falcon Next-Gen SIEM. You must understand first-party vs third-party data sources, built-in data connectors, Falcon Log Collector deployment and management, connector architecture, sizing specifications, and troubleshooting ingestion issues. This domain is highly practical and scenario-based.

Key Topics

Data ConnectorsFalcon Log CollectorHECSyslogFleet ManagementFirst-Party DataThird-Party Data

Must-Know Concepts

  • How to categorize first-party data (native Falcon telemetry) vs third-party data (external security tools, cloud services, network devices) and their ingestion differences
  • Selecting the appropriate integration method: API-based data connectors for cloud/SaaS sources vs Falcon Log Collector for on-premises syslog/file sources
  • Setting up and maintaining built-in data connectors including authentication, scheduling, and data flow configuration
  • Standard components of third-party connector architecture: source, transport protocol, authentication, parsing pipeline, and destination repository
  • Falcon Log Collector sizing specifications: CPU, memory, disk, and network requirements based on events per second (EPS) throughput
  • Installing and configuring the Falcon Log Collector: supported operating systems (Windows, Mac, Linux), syslog sources (UDP/TCP on port 1514), and HEC sink configuration
  • Fleet management operations: centralized collector management, health monitoring, configuration updates, and scaling strategies
  • Diagnosing and resolving common ingestion complications: missing events, parsing errors, connectivity issues, authentication failures, and throughput bottlenecks

Common Exam Traps

Data connectors are API-based cloud integrations. Falcon Log Collector is deployed software for syslog/file collection. Do not confuse the two integration methods
HEC (HTTP Event Collector) is the transport mechanism for sending data to SIEM, not a data source itself. Log Collectors use HEC sinks to forward data
First-party Falcon data is automatically ingested and parsed. Third-party data often requires custom connector configuration AND custom parser development
Sizing the Falcon Log Collector incorrectly leads to data loss — the exam tests whether you know the relationship between EPS throughput and resource requirements
Fleet management is about managing COLLECTORS, not endpoints. Do not confuse log collector fleet management with Falcon sensor management
Quick Check: Data Ingestion

Question 1 of 3

An organization needs to ingest firewall logs from on-premises Palo Alto devices into Falcon Next-Gen SIEM. The firewalls send logs via syslog. Which integration method should be used?

Domain 330% of exam

Parsing

The heaviest domain at 30% — expect roughly 18 questions on parsing topics. Covers the CrowdStrike Parsing Standard (CPS), data normalization, log format recognition, parser validation, custom parser development, AI-assisted parser generation, advanced parsing syntax, and parser troubleshooting. This domain requires both conceptual knowledge and practical parser-building skills.

Key Topics

CPSECSVendor-Prefixed FieldsParser ValidationCustom ParsersAI ParserLog FormatsNormalization

Must-Know Concepts

  • CrowdStrike Parsing Standard (CPS) framework: based on ECS 8.x, with documented deviations and extensions. CPS-compliant parsers standardize data for detection, dashboards, and analytics
  • Data normalization using CPS: mapping raw vendor fields to standard ECS field names, ensuring consistent query capability across all data sources
  • Vendor-prefixed fields: fields not in ECS are prefixed with 'Vendor.' to maintain clean namespace separation between standard and vendor-specific data
  • Recognizing various log format structures: JSON, CSV, syslog (RFC 3164/5424), CEF, LEEF, key-value pairs, XML, and unstructured text formats
  • Developing parser validation test cases: creating sample log entries, testing field extraction, verifying CPS compliance, and validating edge cases
  • Cloning and adjusting existing parser configurations: duplicating parsers as starting points and modifying field mappings for similar but different sources
  • Building custom parser logic from scratch: regex extraction, field assignment, conditional parsing, and multi-format handling
  • AI-assisted parser generation: using the AI Parser feature to automatically generate parser configurations from sample logs and refining the output
  • Advanced syntax features: nested field extraction, conditional logic, multi-line log handling, and complex regex patterns for parser development
  • Identifying and correcting parsing operation failures: debugging field extraction errors, handling format changes, and resolving CPS compliance issues

Common Exam Traps

CPS is based on ECS but is NOT identical to ECS. It has documented deviations and extensions — do not assume all ECS rules apply directly to CPS
Non-ECS fields are prefixed with 'Vendor.' — not dropped or ignored. ALL fields from the raw log should be made available as LogScale fields
Parser validation must include test data. CrowdStrike requires parsers to include test cases — a parser without validation tests is not CPS-compliant
AI-assisted parsers are a starting point, not production-ready. They often require manual review, refinement, and additional test cases before deployment
Log format recognition is tested — you must identify whether a log sample is JSON, syslog, CEF, CSV, or unstructured text before building a parser
Quick Check: Parsing

Question 1 of 3

A parser encounters a field in a raw log called 'fw_action' that does not have an equivalent in the Elastic Common Schema. How should this field be handled according to CPS?

Domain 426% of exam

Content Creation

This domain covers creating operational content within Falcon Next-Gen SIEM: managing lookup data, using pre-built dashboards, writing and optimizing CQL queries, building custom dashboards, creating and tuning correlation rules, and understanding detection source types. This domain is heavily CQL-focused and requires strong query-writing skills.

Key Topics

CQL QueriesDashboardsCorrelation RulesLookup FilesDetection SourcesQuery Optimization

Must-Know Concepts

  • Managing lookup data files: creating, uploading, and referencing lookup data for event enrichment and threat correlation in CQL queries
  • Using pre-built dashboards for system activity observation: understanding default dashboards, their data sources, and how to interpret visualizations
  • CQL query construction: pipe syntax, filter expressions, comparison operators, logical operators (AND, OR — note OR binds closer than AND), field selection, and aggregation
  • CQL functions: groupBy() for deduplication, stats(count()) for aggregation, top() for ranking, eval() for calculated fields, regex() for pattern extraction, rename(), replace(), sort(), formatTime()
  • CQL query optimization: reducing query scope with time ranges and filters, using efficient aggregation, minimizing regex on large datasets, and leveraging indexed fields
  • Building custom dashboard visualizations: widget types, data source binding, interactive drill-down, and real-time vs historical data views
  • Creating correlation rules: defining detection logic in CQL, setting severity levels, assigning MITRE ATT&CK techniques, and configuring alert actions
  • Tuning correlation rule behavior: adjusting thresholds, adding exclusions, refining time windows, and reducing false positives without losing true positives
  • Categorizing vendor-native vs external detection sources: understanding which detections come from CrowdStrike modules vs third-party forwarded alerts

Common Exam Traps

In CQL, OR binds closer than AND — this is different from most programming languages. Parentheses may be needed to ensure correct logical evaluation
The eval() function uses := syntax for field assignment, not = which is used for comparison. field := value creates a new field; field = value filters
Pre-built dashboards require specific data sources to be ingested. If the underlying data connector is not configured, the dashboard will show no data — this is not a dashboard error
Correlation rules and CQL search queries use the same syntax but serve different purposes: rules are persistent detections, queries are ad-hoc investigations
Tuning a correlation rule means adjusting its LOGIC, not disabling it. The exam tests whether you can refine rules to reduce false positives while maintaining detection coverage
Quick Check: Content Creation

Question 1 of 3

A SIEM engineer wants to find the top 10 source IP addresses generating the most failed login events in the last 24 hours. Which CQL query pattern is correct?

Domain 510% of exam

Automation and Integration

This domain covers automating security operations using Falcon Fusion SOAR workflows, generating API authentication credentials, and implementing API integrations using the FalconPy SDK. While the smallest domain by weight, it tests practical automation skills that bridge SIEM data with response actions.

Key Topics

Falcon Fusion SOARFalconPy SDKAPI CredentialsWorkflow AutomationOAuth 2.0

Must-Know Concepts

  • Falcon Fusion SOAR workflow capabilities: no-code visual builder, scheduled/on-demand/event-triggered workflows, first-party and third-party actions, and natural language workflow generation
  • SOAR workflow action types: device queries, email notifications, Jira ticket creation, log writing, host containment, and custom HTTP actions
  • API authentication credential generation: creating OAuth 2.0 Client ID and Client Secret pairs, scoping permissions, and managing credential lifecycle
  • FalconPy SDK implementation: Service Classes (per-API-collection) vs Uber Class (single interface), automatic token management, and basic API interaction patterns
  • HTTP Actions in SOAR: three authentication methods (API keys, OAuth 2.0, CrowdStrike-specific), integration with external tools and services

Common Exam Traps

Falcon Fusion SOAR is NO-CODE — workflows are built visually, not through programming. But API integrations via FalconPy DO require Python code
FalconPy handles OAuth token management automatically — you do not need to manually refresh tokens. But you DO need to provide Client ID and Client Secret
SOAR workflows can be triggered by correlation rule detections, but they are configured separately from the rules themselves
The Workflow Generation Agent uses natural language to CREATE workflows, but executing custom actions still requires proper API credentials and permissions
Quick Check: Automation and Integration

Question 1 of 3

A security team wants to automatically contain a host and create a Jira ticket when a critical severity correlation rule fires. Which approach should be used?

Concepts You Must Not Confuse

These pairs appear on nearly every exam. Learn the difference and you'll avoid the most common traps.

First-Party Data vs Third-Party Data

Use First-Party Data when…

Native Falcon telemetry generated by CrowdStrike products: endpoint detection (EDR), cloud security, identity protection, and Falcon sensor data. Automatically ingested and parsed.

Use Third-Party Data when…

External data from non-CrowdStrike sources: firewalls, cloud providers, network devices, identity platforms, and other security tools. Requires connectors or log collectors for ingestion.

Exam trap

First-party data is automatically parsed and normalized. Third-party data requires configuring connectors, deploying log collectors, and often building custom parsers to comply with CPS.

Data Connectors vs Falcon Log Collector

Use Data Connectors when…

API-based integrations that pull data directly from third-party services (cloud APIs, SaaS platforms). Configured within the Falcon console with built-in authentication.

Use Falcon Log Collector when…

Software deployed on-premises to collect logs from sources that send data via syslog, file, or other protocols. Forwards data to SIEM via HEC sinks.

Exam trap

Data connectors are cloud-to-cloud API integrations. Falcon Log Collector is deployed infrastructure for on-premises or syslog sources. Know which method is appropriate for each data source type.

CPS (CrowdStrike Parsing Standard) vs Raw Log Format

Use CPS (CrowdStrike Parsing Standard) when…

Standardized schema based on ECS 8.x that normalizes all fields to a common format. Non-ECS fields are prefixed with 'Vendor.' for namespace separation.

Use Raw Log Format when…

Original, unprocessed log data as received from the source. Contains vendor-specific field names, formats, and structures that vary between sources.

Exam trap

CPS normalization maps raw vendor fields to standard ECS fields. Fields without an ECS equivalent get a 'Vendor.' prefix. The exam tests whether you understand this mapping and can identify correct CPS field names.

Correlation Rules vs CQL Search Queries

Use Correlation Rules when…

Persistent detection rules that run continuously against incoming data and generate alerts when conditions are met. Used for automated threat detection.

Use CQL Search Queries when…

Ad-hoc or saved queries used for manual investigation, data exploration, and dashboard creation. Run on-demand by analysts.

Exam trap

Both use CQL syntax, but correlation rules are persistent detections that trigger alerts automatically. Search queries are on-demand investigations. A correlation rule becomes a detection source; a query does not.

Vendor-Native Detections vs External Detection Sources

Use Vendor-Native Detections when…

Detection alerts generated natively by CrowdStrike Falcon modules (EDR, identity protection, cloud security). Automatically appear in the SIEM with full Falcon context.

Use External Detection Sources when…

Detection alerts forwarded from third-party security tools (firewalls, other EDR products, cloud security services) into Falcon Next-Gen SIEM via connectors or log collectors.

Exam trap

Vendor-native detections have richer Falcon context and are already mapped to CPS. External detections may require additional parsing and normalization before they can be correlated with native data.

Custom Parsers vs AI-Assisted Parsers

Use Custom Parsers when…

Manually written parser logic that extracts and maps fields from raw logs to CPS-compliant format. Full control over parsing logic, field mapping, and validation.

Use AI-Assisted Parsers when…

AI-generated parser configurations created automatically from sample log data. Accelerates parser development but may require manual refinement for edge cases.

Exam trap

AI-assisted parsers speed up development but are not always production-ready. Custom parsers give full control. The exam tests when each approach is appropriate and how to validate parser output.

Falcon Fusion SOAR Workflows vs Manual Investigation

Use Falcon Fusion SOAR Workflows when…

Automated response playbooks that execute predefined actions (contain host, create ticket, send notification) when triggered by detections or schedules. No-code visual builder.

Use Manual Investigation when…

Analyst-driven investigation using CQL queries, dashboards, and the Incident Workbench. Requires human judgment and manual action execution.

Exam trap

SOAR workflows automate repetitive response actions but do not replace analyst judgment for complex investigations. The exam tests when automation is appropriate vs when manual investigation is needed.

Top Mistakes to Avoid

Confusing data connectors (API-based cloud integrations) with Falcon Log Collector (deployed software for syslog/file collection) — each serves different data source types
Assuming CPS is identical to Elastic Common Schema (ECS) — CPS is based on ECS 8.x but has documented deviations and extensions specific to CrowdStrike
Forgetting that non-ECS fields are prefixed with 'Vendor.' in CPS — they are NOT dropped or ignored, all raw log fields must be preserved
Using = instead of := in CQL eval() statements — = is for comparison/filtering, := is for field assignment and creation
Not knowing that OR binds closer than AND in CQL — this differs from most programming languages and can cause incorrect query logic without parentheses
Treating AI-assisted parsers as production-ready without validation — AI-generated parsers are starting points that require manual review and test case verification
Confusing correlation rules (persistent automated detections) with CQL search queries (ad-hoc investigations) — both use CQL syntax but serve fundamentally different purposes
Mixing up Falcon Log Collector fleet management with Falcon sensor management — fleet management refers to managing log collectors, not endpoint agents
Thinking Falcon Fusion SOAR requires coding — SOAR uses a no-code visual builder, while API integrations via FalconPy require Python
Underestimating the Parsing domain (30%) and Data Ingestion domain (27%) — together they account for 57% of the exam and require practical knowledge
