CompTIA CySA+ (CS0-003) Study Guide [160 Minute Read]

A First-Principles Approach to Cybersecurity Analysis

Security analysts don't just react to alerts — they build the mental models that let them distinguish signal from noise, recognize attack patterns before they escalate, and communicate risk clearly to those who need to act. This guide teaches the why behind every concept, so you can reason through novel scenarios on exam day rather than just recalling memorized facts.

Official Exam Objectives: CompTIA CySA+ CS0-003 Exam Objectives

The CySA+ exam uses "Given a scenario" phrasing in 3 of 5 domain objectives — expect at least 40% of questions to present a situation requiring applied judgment, not just recall. You'll encounter multiple-choice and performance-based questions (PBQs) that ask you to interpret logs, analyze tool output, or select the right response action.

Exam Details: 85 questions maximum · 165 minutes · Passing score: 750/900 · Recommended: 4 years hands-on SOC/IR experience

Exam Domain Weights

Security Operations and Vulnerability Management together account for 63% of the exam — master these two domains first. Incident Response and Reporting round out the picture with the communication and process skills that distinguish a junior analyst from a senior one.
