Discover how a cybersecurity analyst monitors, detects, analyzes, and responds to threats across tier 1–3 in modern hybrid environments. Leverage SIEM, EDR, MITRE ATT&CK, and SOAR.
Navigate the CS0-004 CySA+ course with a four-phase roadmap from operating environment, through detection and analysis and vulnerability management and incident response, to reporting and communication.
Outline the SOC tier structure and roles from tier 1 alert triage to tier 3 threat hunting, and explain specialist roles like threat intelligence analyst and incident responder.
Understand risk in cybersecurity as the intersection of threat, vulnerability, and impact. Learn to measure it with quantitative and qualitative methods for informed prioritization.
Explore inherent risk, residual risk, and risk appetite, and learn how controls and risk tolerance shape risk management using the six-step RMF.
Examine administrative, technical, and physical controls, how defense in depth layers them to protect assets, and how compensating controls mitigate gaps in legacy systems to reduce risk.
Explore how administrative, technical, and physical controls serve preventive, detective, responsive, and corrective functions to stop, detect, contain, and recover from incidents.
Learn containerization with Docker and Kubernetes, and identify risks like poisoned images, container escapes, and exposed API servers; monitor with Falco and Kubernetes audit log, applying least privilege.
Detect potential API enumeration through log analysis by examining repeated requests and sequential user IDs, and assess for broken object-level authorization.
Adopt ZTNA by never trusting by default and always verifying, using IAM, device trust, and microsegmentation with policy based enforcement. This improves access controls and reduces blast radius.
Explore industrial control systems as the OT subset that automates processes with PLCs, a control server, HMIs, and the data historian, and distinguish DCS from SCADA for security implications.
Explore how SCADA systems manage multi-site operations with MTU and RTUs, how IP-based communications expand attack surfaces, and Stuxnet's threat model.
Map OS architecture to detection strategy by examining the kernel and user space boundaries, and hardware protections like ASLR and DEP, with OS telemetry driving threat hunting and security operations.
Learn how time synchronization with NTP keeps clocks aligned for log analysis and timelines, covering stratum levels, UDP 123, UTC logging, and mitigations like disabling monlist and authenticated NTP.
Master identity and access management fundamentals, including identity management and authentication. Explore authorization, federation, single sign-on, least privilege, orphaned accounts, and sign-in logs for threat detection.
Explore authorization models and mechanisms, including DAC, MAC, RBAC, ABAC, and PBAC, and apply least privilege and ACLs to detect and analyze access misuse in enterprise environments.
Identify data states: at rest, in transit, and in use, and apply encryption and data loss prevention. Recognize PII, PHI, and CHD with GDPR, HIPAA, and PCI DSS.
Become a Skilled Cybersecurity Analyst
Cybersecurity professionals play a critical role in protecting organizations from today's evolving threat landscape. The CompTIA CySA+ (CS0-004) certification validates the practical skills needed to detect threats, manage vulnerabilities, respond to security incidents, and support modern Security Operations Center (SOC) environments.
Dion Training's CompTIA CySA+ (CS0-004) Certification Course is designed to help you confidently prepare for the latest certification exam while developing the real-world knowledge employers value. Through expert instruction, comprehensive study materials, and exam-focused practice, you'll learn how to analyze security events, prioritize vulnerabilities, investigate incidents, and effectively communicate security findings. The course is fully aligned with the official CompTIA CS0-004 exam objectives and emphasizes practical application to help you succeed on the exam and in your cybersecurity career.
Course Domains
The CompTIA CySA+ (CS0-004) certification exam measures knowledge across four primary domains:
Security Operations (34%) Learn the core responsibilities of modern security operations, including system and network architecture, threat detection, malicious activity analysis, threat intelligence, security monitoring, automation, and the role of AI in cybersecurity operations. This domain builds the analytical skills needed to identify and respond to threats within enterprise environments.
Vulnerability Management (26%) Develop the knowledge required to identify, assess, prioritize, and mitigate vulnerabilities across an organization's infrastructure. You'll explore vulnerability scanning methodologies, assessment tools, risk-based remediation, governance concepts, and best practices for reducing an organization's attack surface.
Incident Response and Management (24%) Master the incident response lifecycle by learning how to prepare for, detect, analyze, contain, eradicate, recover from, and document cybersecurity incidents. You'll also examine attack frameworks, evidence handling, root cause analysis, and response planning to effectively manage security events.
Reporting and Communication (16%) Build the communication skills needed to deliver meaningful security reports to technical teams, management, and stakeholders. This domain covers vulnerability reporting, incident documentation, executive summaries, security metrics, compliance reporting, and communicating actionable recommendations that support informed business decisions.
