🛡 CompTIA CySA+ CS0-003 Study Guide

Comprehensive coverage of all four exam domains. Click each domain to expand topics, tools, and exam tips.

33%Domain 1: Security Operations
▼

The largest domain. Covers threat intelligence, threat hunting, SIEM/SOAR/EDR/XDR tooling, log analysis, network monitoring, identity monitoring, and implementing security controls in enterprise environments including cloud.

SIEM Architecture & Log Analysis
SOAR — Playbooks & Automation
EDR / XDR Platforms
Threat Intelligence (OSINT, ISACs)
Threat Hunting Methodology
MITRE ATT&CK Framework
IOC vs IOA Analysis
Network Traffic Analysis (Wireshark, Zeek)
Endpoint Detection & Forensics
Identity & Access Monitoring (PAM/UBA)
Cloud Security Monitoring (CSPM)
Zero Trust Architecture
Honeypots & Deception Technology
Firewall / IDS / IPS Analysis

EXAM TIPS

  • Know the difference between IOC (Indicator of Compromise — evidence of breach) and IOA (Indicator of Attack — evidence of attacker behavior in progress)
  • Understand MITRE ATT&CK tactics, techniques, and procedures (TTPs) — especially Initial Access, Execution, Persistence, and Exfiltration
  • Know SIEM use cases: log aggregation, correlation rules, dashboards, alerting — and when to escalate to SOAR automation
  • Distinguish between EDR (endpoint), NDR (network), and XDR (cross-layer) detection and response platforms
  • Threat hunting is proactive; incident response is reactive — know the difference
30%Domain 2: Vulnerability Management
▼

Covers the full vulnerability management lifecycle: asset discovery, scanning (credentialed vs. non-credentialed, active vs. passive), CVSS scoring, prioritization, remediation, and validation. Also includes application and cloud vulnerability assessment.

CVSS v3 Scoring (Base, Temporal, Env)
CVE / NVD / EPSS Databases
Vulnerability Scanners (Nessus, Qualys, OpenVAS)
Credentialed vs. Non-Credentialed Scans
Active vs. Passive Scanning
Asset Discovery & Inventory
Web App Scanning (Burp Suite, OWASP ZAP)
OWASP Top 10 Vulnerabilities
Patch Management Process
Risk Prioritization & Acceptance
False Positives & Validation
Cloud Infrastructure Assessment

EXAM TIPS

  • CVSS Base Score: 0.0–10.0. Critical = 9.0–10.0, High = 7.0–8.9, Medium = 4.0–6.9, Low = 0.1–3.9
  • Credentialed scans provide deeper results (registry, installed software); non-credentialed scans see only exposed services
  • EPSS (Exploit Prediction Scoring System) estimates likelihood of exploitation in the wild — used alongside CVSS for prioritization
  • Know patch management stages: identify → assess → test → deploy → verify → document
  • False positives waste analyst time; always validate findings before remediating
20%Domain 3: Incident Response & Management
▼

Covers the full incident management lifecycle from preparation through lessons learned. Includes attack frameworks, containment/eradication/recovery procedures, digital forensics, and chain of custody.

NIST SP 800-61 IR Lifecycle
Preparation & IR Planning
Detection & Analysis
Containment Strategies (Short/Long-term)
Eradication & Recovery
Post-Incident Activity / Lessons Learned
Attack Frameworks (Kill Chain, ATT&CK, Diamond)
Digital Forensics & Chain of Custody
Memory & Disk Imaging (dd, FTK, Autopsy)
Malware Analysis (Static vs. Dynamic)
Tabletop Exercises & Simulations

EXAM TIPS

  • NIST IR Lifecycle: Preparation → Detection & Analysis → Containment, Eradication & Recovery → Post-Incident Activity
  • Cyber Kill Chain stages: Reconnaissance → Weaponization → Delivery → Exploitation → Installation → C2 → Actions on Objectives
  • Order of volatility for forensics: CPU registers → RAM → Swap/pagefile → Network state → Running processes → Disk → Backups
  • Chain of custody must be maintained for evidence to be admissible — document every person who touches evidence
  • Containment isolates the threat; eradication removes it; recovery restores normal operations
17%Domain 4: Reporting & Communication
▼

Focuses on communicating technical findings to varied audiences, creating vulnerability management reports, incident reports, metrics/KPIs, and understanding regulatory compliance frameworks relevant to security analysts.

Vulnerability Management Reporting
Incident Reporting & Documentation
Executive vs. Technical Reporting
KPIs & Security Metrics (MTTD, MTTR)
Risk Register & Risk Appetite
Compliance Frameworks (NIST, ISO 27001, SOC 2)
GDPR / HIPAA / PCI-DSS Reporting
Stakeholder Communication
Root Cause Analysis (RCA)
Remediation Timelines & SLAs

EXAM TIPS

  • MTTD (Mean Time to Detect) and MTTR (Mean Time to Respond/Recover) are key SOC performance metrics — lower is better
  • Executive reports focus on risk, business impact, and trends. Technical reports include CVEs, CVSS scores, affected assets, and remediation steps
  • Know the difference between a risk register (comprehensive risk inventory) and a risk appetite (how much risk leadership accepts)
  • Understand mandatory breach notification timelines: GDPR = 72 hours, HIPAA = 60 days, some state laws = immediately
