COMPTIA CYSA+ · CS0-004
Security operations, vulnerability management, incident response and reporting — 17 chapters and 268 pages built on the CS0-004 objectives, with 12 step-by-step PBQ walkthroughs and an Objective-to-Page Map that takes every objective straight to the page that covers it.
EXAM OVERVIEW
CompTIA CySA+ is the analyst-level certification for the defensive side of security: monitoring and detection, vulnerability management, incident response, and the reporting that turns findings into decisions. CS0-004 is the V4 revision of the exam — the one that brings AI security and SOAR into the objectives, where CS0-003 had neither.
DOMAINS
