CompTIA Security+ Study Guide (2026)

CompTIA Security+ is the classic first cybersecurity certification — vendor-neutral, widely recognized by employers and HR filters, and a great way to prove you've got the fundamentals. Here's how to prepare.

Who it's for

Security+ is ideal if you're starting out or moving into security from IT. It's broad and foundational rather than specialized — perfect before you pick a niche. (For the pentesting path specifically, see CEH and OSCP.)

What it covers

The exam spans several domains:

• General security concepts — the CIA triad, controls, cryptography basics.
• Threats, vulnerabilities & mitigations — malware, phishing, attack types.
• Security architecture — secure design, firewalls, network security, cloud.
• Security operations — monitoring, incident response, vulnerability management.
• Governance, risk & compliance — policies, frameworks, risk concepts.

Expect both multiple-choice and performance-based questions (scenario tasks).

A 4–6 week study plan

• Week 1: core concepts + cryptography basics.
• Week 2: threats, attacks, and vulnerabilities.
• Week 3: architecture, network & cloud security.
• Week 4: operations, IR, and GRC.
• Weeks 5–6: practice exams + drill weak domains and performance-based questions.

Study tips

1. Understand, don't memorize — Security+ tests application of concepts.
2. Learn the acronym soup — there's a lot; use flashcards / spaced repetition.
3. Do performance-based practice — they trip people who only studied multiple choice.
4. Take timed practice exams until you're consistently comfortable.

Free foundation

Many Security+ topics overlap with general security fundamentals. Our free Pentevo Academy and beginner guide — Cyber Security for Beginners — give you a solid, no-cost base to build on before exam day.
