Exam overview
Security+ is a single exam with multiple-choice and performance-based questions (PBQs). The certification is valid for three years and renewed through continuing education.
Exam details such as price, length and question count change periodically — always confirm current information on the official certification page before you book.
Exam domains
- General security concepts — security controls, the CIA triad, zero trust and cryptography basics
- Threats, vulnerabilities and mitigations — threat actors, attack types and mitigation techniques
- Security architecture — cloud, network and infrastructure security, data protection and resilience
- Security operations — monitoring, identity and access management, incident response and automation
- Security program management and oversight — governance, risk, compliance, third-party risk and security awareness
Key concepts to know
- Common attack categories: phishing, ransomware, web application attacks, on-path attacks and password attacks
- Cryptography: symmetric vs. asymmetric, hashing, PKI and certificates
- Identity: MFA, SSO, federation, least privilege and privileged access management
- Network security: firewalls, IDS/IPS, segmentation, VPNs and secure protocols
- The incident response process and digital forensics basics
- Risk management, business impact analysis and compliance frameworks
How to handle performance-based questions
PBQs may ask you to configure firewall rules, match threats to descriptions or analyze logs. Many candidates skip PBQs at first, answer the multiple-choice questions and then return with remaining time. Practice simulations during your preparation.
A 6–8 week study plan
- Weeks 1–2: General concepts and cryptography
- Weeks 3–4: Threats, vulnerabilities and architecture
