What Does Security+ Cover?
The CompTIA Security+ SY0-701 exam covers six major domains that together form a comprehensive overview of modern cybersecurity practices. Understanding these domains helps you grasp the breadth of knowledge required and the real-world relevance of each topic.
Domain 1: General Security Concepts (13% of exam)
This foundational domain covers the principles that underpin all security work. You'll learn about the CIA Triad (Confidentiality, Integrity, Availability), the fundamental building blocks of any security program. You'll also explore common security frameworks and governance models, including NIST Cybersecurity Framework, ISO 27001, and CIS Controls. Risk management concepts are introduced here, teaching you how to identify, assess, and prioritize security risks. Understanding security culture and organizational practices is essential, as you'll need to recognize how people and processes, not just technology, create effective security.
Domain 2: Threats, Vulnerabilities, and Mitigations (21% of exam)
This is the largest domain and covers the threats that security professionals encounter daily. You'll study malware types including viruses, worms, trojans, ransomware, and spyware. Social engineering attacks like phishing, pretexting, and baiting are examined in depth because they remain the most common attack vectors. Physical security threats, environmental controls, and facility hardening are important aspects often overlooked in purely technical security training. Vulnerability assessment, patch management, and secure coding practices round out this practical domain.
Domain 3: Security Architecture (21% of exam)
This domain teaches you how to design and implement secure systems. You'll learn network security concepts including firewalls, intrusion detection systems, VPNs, and wireless security. Cloud security architecture covers the unique challenges of securing Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) environments. Application security includes understanding secure development lifecycles, API security, and container security. Defense-in-depth strategies and zero-trust architecture principles are covered, reflecting modern security thinking.
Domain 4: Identity and Access Management (16% of exam)
Identity and access management (IAM) is critical to modern security. You'll master authentication methods including multi-factor authentication (MFA), biometrics, and smart cards. Authorization and access control models like Role-Based Access Control (RBAC) and Attribute-Based Access Control (ABAC) are examined. Privilege management, password policies, and identity federation are essential skills. This domain also covers compliance considerations related to access control and privacy regulations.
Domain 5: Cryptography and PKI (16% of exam)
Cryptography is fundamental to modern security, and this domain demystifies complex concepts. You'll learn symmetric encryption (like AES), asymmetric encryption (like RSA), and hashing algorithms. Public Key Infrastructure (PKI) is explored in detail, including how certificates work, certificate authorities, and the importance of certificate management. Digital signatures, key management practices, and common cryptographic failures are all covered. This isn't about doing cryptography yourself, but understanding when and how it's used to protect data.
Domain 6: Compliance, Governance, and Risk Management (13% of exam)
The final domain brings security into the business context. You'll study major compliance frameworks like GDPR (Europe), HIPAA (healthcare), PCI-DSS (payment cards), and NIST frameworks. Governance structures, incident management processes, and business continuity planning are essential topics. Data classification, data handling policies, and privacy concepts are covered. You'll also learn about managing third-party risks, vendor assessment, and supply chain security, which have become increasingly important.
The exam emphasizes real-world scenarios, so each domain includes practical applications. For example, rather than just knowing cryptographic algorithms exist, you'll need to understand why AES might be used for data encryption but RSA for key exchange. Rather than memorizing security controls, you'll apply them to specific business scenarios and risk contexts.
SY0-701 Exam Details
Understanding the exam structure, format, and scoring helps you prepare effectively and set realistic expectations for your certification journey.
Exam Format and Question Types
The SY0-701 exam contains approximately 90 questions that you must complete in 90 minutes. This translates to roughly one minute per question, though some questions require more thought than others. The exam uses three types of questions:
- Multiple-choice questions: You select one correct answer from four options. These test your knowledge of concepts, tools, and best practices.
- Multiple-response questions: You must select all correct answers from a list, typically containing four to six options. These require more precision, as partial credit is not awarded.
- Performance-based items (PBIs): These simulate realistic work scenarios where you might drag-and-drop items, click on elements in a diagram, or configure settings. Approximately 13% of the exam consists of these items, making hands-on knowledge essential.
Scoring and Passing Standards
The SY0-701 exam uses a scaled scoring system where your raw score (number of correct answers) is converted to a scaled score between 100 and 900. You must achieve a scaled score of 750 or higher to pass. This means approximately 75% of questions must be answered correctly, though the exact percentage varies slightly depending on question difficulty and weighting.
CompTIA publishes score reports immediately after the exam in most testing centers, though computerized results may take up to 24 hours to appear in your official transcript. Your score report breaks down your performance by domain, showing your strengths and weaknesses. Even if you pass, this feedback is valuable for pursuing advanced certifications.
Exam Delivery and Registration
You can take the SY0-701 exam through Pearson VUE testing centers worldwide or via remote proctoring (OnVUE) from your home or office. Both options are available in the US, UK, and Canada. Testing center locations are abundant, and you typically can schedule an exam within 48 hours of deciding to test.
The exam costs approximately $370 USD (prices vary by region and currency). When registering, you'll be asked about your experience level, though this is optional and does not affect the exam content or difficulty. Registration typically takes a few minutes on the Pearson VUE website.
Exam Timing and Scheduling
You have 90 minutes to answer all questions. The exam includes a brief tutorial at the beginning (which you can skip if you've taken other CompTIA exams), and you can flag questions to review later. Time management is important; experts recommend spending no more than one minute per question initially, then returning to flagged questions if time permits.
Exam Refresh and Version Updates
CompTIA updates Security+ approximately every three years to reflect evolving threats and technologies. The SY0-701 version, released in April 2024, represents the latest standards. Previous versions (like SY0-601) are no longer available for new test-takers, though those who passed the older version maintain their certification without requiring an upgrade.

Previous CompTIA A+ or Network+ holders find the exam format familiar, which can reduce anxiety. The key is structured preparation using quality resources rather than last-minute cramming.
Do I need CompTIA A+ before taking Security+?
CompTIA does not require A+ as a prerequisite for Security+. If you have two years of hands-on IT administration or security experience, you can attempt Security+ directly. However, if you lack IT fundamentals like networking, operating systems, or system administration knowledge, completing A+ first provides valuable foundational knowledge that makes Security+ more understandable. Some career changers benefit from A+ as preparation, while experienced IT professionals can skip directly to Security+. Assess your own IT knowledge and adjust your learning path accordingly.
How long does Security+ certification last?
CompTIA Security+ certification is valid for three years from your passing exam date. After three years, you must either retake the exam or complete a continuing education (CE) requirement to maintain your credential. CE options include passing a higher-level CompTIA certification, completing approved security training courses, publishing security-related work, or earning other approved vendor certifications. This three-year renewal cycle keeps certified professionals engaged with evolving security practices and emerging threats.
Can I take Security+ if I have no IT experience?
Officially, CompTIA recommends two years of IT experience before attempting Security+. Without IT background, the exam becomes significantly more challenging because it assumes familiarity with networking, operating systems, and system administration. However, motivated learners without IT experience can succeed by investing additional study time. We recommend taking CompTIA A+ first to build foundational IT knowledge, then proceeding to Security+. Alternatively, choose a comprehensive training program that explains IT fundamentals alongside Security+ content to bridge knowledge gaps. Plan for 100+ hours of study if you're starting without IT background.
What's the difference between Security+ and CEH?
CompTIA Security+ and Certified Ethical Hacker (CEH) are complementary but distinct certifications. Security+ is vendor-neutral and foundational, covering broad security concepts like authentication, encryption, and compliance. It's ideal for security administrators, analysts, and IT professionals entering security roles. CEH is more specialized and offensive-focused, emphasizing penetration testing and vulnerability exploitation. CEH is typically pursued by professionals specifically interested in ethical hacking and penetration testing careers. Most professionals complete Security+ first to build foundational knowledge, then pursue CEH if they're interested in specialized testing roles. Security+ is broader and more immediately applicable to most security jobs, while CEH requires additional specialized knowledge.
Is Security+ recognized internationally?
Yes, CompTIA Security+ is recognized globally and is particularly valued in the United States, United Kingdom, Canada, and Australia. It's vendor-neutral and not tied to specific tools or geographic regions, making it portable across countries. However, government contractor requirements vary by country. In the U.S., Security+ is DoD 8570.01 compliant, meaning it's mandated for many government positions. In other countries, employers value it highly but may have different specific preferences. Internationally, Security+ demonstrates adherence to NIST and ISO security standards, both widely respected globally. If you're working internationally or considering relocation, Security+ significantly enhances your marketability in English-speaking countries.
What happens if I fail the Security+ exam?
If you don't pass Security+, you can retake the exam after waiting 14 days. CompTIA doesn't limit retakes, so you can attempt the exam as many times as necessary. Your failed exam score helps identify knowledge gaps. Most candidates who fail their first attempt pass on the second try, usually after 20-30 hours of additional focused study on weak domains. Your practice exam performance before test day should predict your pass likelihood. If you're scoring below 75% on practice exams, additional study before attempting the real exam is recommended. Retake costs the same as the initial exam ($370 USD approximately), so budget for potential retakes in your certification planning.
