CompTIA Security+ (SY0-701) Study Guide [240 Minute Read]

A First-Principles Approach to Cybersecurity

Welcome to the CompTIA Security+ (SY0-701) Study Guide. This guide moves beyond surface-level memorization. It is designed to build a robust mental model of how cybersecurity works across enterprise environments — understanding the why behind every security decision, architecture choice, and incident response action.

Each topic is aligned with the official CompTIA Security+ Exam Objectives (SY0-701), targeting the specific cognitive skills required for success. Roughly half the exam questions are scenario-based, requiring you to apply concepts to real-world situations rather than simply recalling definitions. Performance-Based Questions (PBQs) test hands-on skills in simulated environments like configuring firewalls or analyzing logs.

Exam Details: Up to 90 questions (multiple-choice + PBQs) | 90 minutes | Passing score: 750/900 (~83%)

Prerequisites: CompTIA recommends Network+ certification and a minimum of 2 years of experience in IT administration with a focus on security. Familiarity with TCP/IP networking, operating systems (Windows and Linux), and basic IT infrastructure concepts is assumed.

Exam Domain Weights

Security Operations dominates at 28%, meaning nearly a third of your exam will cover topics like hardening, vulnerability management, monitoring, identity management, incident response, and automation. Combined with Threats/Vulnerabilities (22%), over half the exam tests your ability to detect, respond to, and prevent security incidents. Don't underestimate the 20% on Security Program Management — governance, risk, and compliance questions are heavily scenario-based and trip up candidates who focus only on technical topics.
