What Is CompTIA Security+?
CompTIA Security+ is a globally recognized, vendor neutral certification that validates baseline skills needed to perform core security functions. It is approved by the U.S. Department of Defense under directive 8140 for several information assurance job roles, which is why so many government and contractor positions list it as a hiring requirement.
Hiring managers trust it because CompTIA updates the exam every three years to reflect modern threats, and it includes performance based questions that require actual problem solving, not just memorization.
Exam Details: SY0-701 in 2026
The current exam code is SY0-701, released by CompTIA in November 2023 and active throughout 2026 and beyond. You need to know the exact specs to plan your prep correctly.
- Number of questions: Maximum of 90
- Question types: Multiple choice (single and multiple response) and performance based
- Time limit: 90 minutes
- Passing score: 750 on a scale of 100 to 900
- Cost: 404 USD (a voucher plus exam bundle is available at discount)
- Delivery: Pearson VUE test center or online proctored
- Validity: 3 years (renewable through CompTIA Continuing Education)
Performance based questions (PBQs) usually appear as the first 3 to 5 items of the exam. They are worth more points than standard multiple choice, and they can rattle candidates who are not prepared for them. A smart tactic: skip them initially (flag for review), work through the multiple choice section first to build confidence and momentum, then return to the PBQs with the remaining time.
The 5 Security+ Domains Explained
The SY0-701 blueprint covers five domains with the following weighting:
Domain 1: General Security Concepts (12 percent)
This is the foundation. Know the CIA triad (confidentiality, integrity, availability), security controls (preventive, detective, corrective, deterrent, compensating, directive), change management basics, and cryptographic concepts including symmetric versus asymmetric encryption, hashing, digital signatures, and public key infrastructure. Zero trust and AAA (authentication, authorization, accounting) show up repeatedly across the exam.
Domain 2: Threats, Vulnerabilities, and Mitigations (22 percent)
The biggest single domain. You need to recognize threat actors (nation state, organized crime, insider threat, hacktivist, script kiddie), attack vectors (phishing, smishing, vishing, watering hole, supply chain), malware types (ransomware, trojans, worms, rootkits, spyware, keyloggers, bloatware, logic bombs), and modern attack techniques like prompt injection on AI systems. Mitigation strategies include hardening, segmentation, isolation, patching, encryption, monitoring, least privilege, and configuration enforcement.
Domain 3: Security Architecture (18 percent)
Covers enterprise network design, cloud models (IaaS, PaaS, SaaS), virtualization, containerization, serverless, microservices, IoT, ICS and SCADA systems, and embedded systems security. Data protection is heavy here: classification (public, private, confidential, critical, restricted), sovereignty, geographic restrictions, encryption at rest and in transit, masking, tokenization, and obfuscation.
Domain 4: Security Operations (28 percent)
The largest domain, and the most hands on. Expect scenarios about hardening (Windows, Linux, mobile, IoT), identity and access management (SSO, federation, SAML, OAuth, OpenID Connect, MFA factors), vulnerability management (scanning, CVSS, CVE, remediation prioritization), monitoring (SIEM, log aggregation, alerts), incident response, digital forensics (chain of custody, acquisition), and automation via scripts and SOAR platforms.
Domain 5: Security Program Management and Oversight (20 percent)
The governance domain. Risk management (risk appetite, tolerance, risk register, KRIs, KPIs), risk assessment types (ad hoc, recurring, one time, continuous), third party risk (due diligence, right to audit, MOU, MSA, SLA, NDA, BPA), compliance (PCI DSS, GDPR, HIPAA, SOX, CCPA), audits, and privacy topics including data subjects, controllers, and processors.
The 10 Week Security+ Study Plan
Ten weeks at 10 to 12 hours per week works for most candidates with some IT background (Network+, A+, or 6 plus months of IT support experience). If you are newer to IT, add 2 to 4 additional weeks for networking fundamentals review.
Week 1: Baseline and Setup
Take a full length SY0-701 diagnostic exam. Record your score per domain. Download the official CompTIA exam objectives PDF and print it. Install a home lab (VirtualBox or VMware Workstation Player is free) and spin up a Windows 10/11 VM plus Kali Linux and Ubuntu Server.
Week 2: Domain 1 (General Security Concepts)
Study the CIA triad, control types, change management, and crypto fundamentals. Drill symmetric versus asymmetric differences. Learn hashing algorithms (SHA-256, SHA-3, bcrypt, Argon2) and when each is used. Complete 50 domain 1 practice questions.
Week 3: Domain 2 Part 1 (Threats and Vulnerabilities)
Memorize threat actor motivations and capabilities. Study malware taxonomy until you can instantly match a scenario to the malware type. Cover social engineering techniques and their specific names. This is a memorization heavy week, so use spaced repetition (Anki is ideal).
Week 4: Domain 2 Part 2 (Mitigations and Indicators)
Focus on indicators of compromise (account lockouts, concurrent sessions, impossible travel, blocked content, resource consumption) and mitigation strategies. Build a one page cheat sheet that maps threats to mitigations. Finish the week with 75 questions covering domain 2.
Week 5: Domain 3 (Security Architecture)
Focus on cloud architecture concepts, responsibility models, and secure network design (DMZ, screened subnets, zero trust, microsegmentation). Learn the differences between IDS, IPS, NGFW, WAF, UTM, and load balancer appliances. Practice drawing sample architectures on paper.
Week 6: Domain 4 Part 1 (Operations and IAM)
Master identity and access management in depth. Understand all MFA factor types (something you know, have, are, do, somewhere you are). Study SSO, federation, SAML assertions, OAuth flows, and directory services (LDAP, Active Directory, Kerberos). Complete hands on labs in your Windows VM: create users, groups, and group policies.
Week 7: Domain 4 Part 2 (Monitoring, Incident Response, Forensics)
Cover SIEM tools, log sources (authentication, firewall, application, endpoint), and alert tuning. Learn the incident response lifecycle (preparation, identification, containment, eradication, recovery, lessons learned). Study digital forensics: chain of custody, volatile data order, reporting. Run Wireshark captures in your home lab for hands on exposure.
Week 8: Domain 5 (Governance and Risk)
Memorize risk terminology and the quantitative risk formulas: ALE equals ARO times SLE, and SLE equals asset value times exposure factor. Know the third party agreement types and what each one covers. Study key regulations by industry.
Week 9: Full Length Practice and Weak Spot Review
Take two full length timed practice exams. Analyze every miss and categorize as knowledge gap, misread question, or trap answer. Rebuild your flashcards from the gap list. Spend the remaining time re reviewing weak domains.
Week 10: Final Drill and Exam
Take one more timed practice exam no later than 4 days before exam day. Spend the final days on spaced repetition and PBQ practice. Schedule exam day as late in the morning as possible so you are fully awake. Sleep 8 hours the night before and eat a protein rich breakfast.
Hands On Labs and Tools
Security+ is not purely theoretical. Candidates who only read books struggle with PBQs and with real interview questions that follow. Set aside at least 2 hours per week for labs.
- Wireshark: Capture packets on your home network. Identify common protocols (HTTPS, DNS, DHCP, ARP).
- Nmap: Scan your own VMs. Learn the difference between a TCP connect, SYN, and UDP scan. Understand port states.
- Metasploit (Kali Linux): Exploit a purposely vulnerable VM like Metasploitable 2 in an isolated lab network.
- OpenVAS or Nessus Essentials: Run a vulnerability scan on a test VM and interpret results including CVSS scores.
- Active Directory (Windows Server 2022 trial): Build a small domain, create users and group policies, and harden it.
- Splunk Free: Ingest logs and build simple detection searches.
All of these are free or have free tiers, and the experience carries directly into your first cybersecurity role.
Performance Based Question Strategy
PBQs are interactive simulations. You might configure firewall rules, identify attacks from log entries, or complete a partial network diagram. They typically appear at the start of the exam.
The best strategy is threefold. First, flag PBQs for review and move on. Multiple choice questions are faster, so ensure you have time for all of them. Second, when you return to PBQs, read the entire scenario before touching anything. Third, partial credit is awarded, so doing something is always better than leaving it blank.
Sample Security+ Questions with Explanations
Sample Question 1
A security analyst notices that a user account is logging in from New York and London within a 10 minute window. Which indicator of compromise is this?
A) Account lockout
B) Impossible travel
C) Resource consumption
D) Concurrent session usage
Answer: B. Impossible travel refers specifically to authentication events from geographically distant locations within a window that is physically impossible to traverse.
Sample Question 2
Which cryptographic approach uses a pair of mathematically linked keys, one public and one private?
A) Symmetric encryption
B) Asymmetric encryption
C) Hashing
D) Steganography
Answer: B. Asymmetric encryption (also called public key cryptography) uses two linked keys. Symmetric uses one shared key. Hashing is one way and uses no keys.
Sample Question 3
A company wants to limit the blast radius of a compromised user account. Which principle should it implement?
A) Separation of duties
B) Least privilege
C) Implicit deny
D) Mandatory vacation
Answer: B. Least privilege grants users only the access they need to do their job, limiting damage if the account is compromised.
Sample Question 4
Which document establishes a mutual intent to cooperate between two organizations but is not legally binding?
A) SLA
B) MSA
C) MOU
D) NDA
Answer: C. A Memorandum of Understanding outlines intent and expectations but is typically non binding. SLAs and MSAs are enforceable contracts. An NDA is also binding but focuses on confidentiality.
Sample Question 5
An organization has an asset valued at 200,000 USD, an exposure factor of 0.25, and an annualized rate of occurrence of 0.5. What is the ALE?
A) 10,000 USD
B) 25,000 USD
C) 50,000 USD
D) 100,000 USD
Answer: B. SLE equals 200,000 times 0.25 which is 50,000. ALE equals SLE times ARO, so 50,000 times 0.5 equals 25,000.
Common Mistakes to Avoid
Relying on one study resource. No single book or video course covers every objective in the depth the exam demands. Use at least two sources: a primary (like an official CompTIA Study Guide or a trusted video course) and a secondary for reinforcement.
Memorizing acronyms without understanding. Security+ is acronym heavy, but the exam tests application. You must know not just what SAML stands for but when to use it versus OAuth, and what a SAML assertion looks like in practice.
Neglecting the hands on component. PBQs plus the real world value of certification both require practical exposure. Skipping labs is a shortcut that costs you points and costs you job offers later.
Taking the exam too early. A practice test passing score of 75 percent in a reputable question bank is the minimum signal that you are ready. If you are only scoring 65, wait another two weeks.
Ignoring the time limit. 90 minutes for up to 90 questions plus PBQs means an average of 60 seconds per multiple choice and more on PBQs. Practicing untimed drills gives a false sense of readiness. Always include timed sets.
Skipping the exam objectives document. CompTIA publishes the exact objectives. Every single test item is mapped to one. If you have not read the objectives list from top to bottom, you almost certainly have content gaps.
Exam Day Strategy
Arrive at the testing center or start your online proctored session 30 minutes early. Have two forms of valid ID and a clean testing space if you are remote. Verify your webcam, mic, and browser work well in advance.
Once in the exam, spend the first minute skipping through the first screens if they are PBQs. Then work through multiple choice as quickly as possible without sacrificing accuracy. Flag questions you are unsure about. After the multiple choice section, return to PBQs with a fresh mind. Save the last 10 minutes for flagged items and a final scan.
Do not leave any question blank. There is no penalty for wrong answers on Security+.
Frequently Asked Questions
1. How hard is the Security+ exam compared to other CompTIA certs?
Security+ is harder than A+ and Network+ because of its breadth and the performance based questions. Most candidates rate it as moderately difficult with 10 to 12 weeks of focused prep. It is significantly easier than CySA+, PenTest+, or CISSP.
2. Do I need Network+ before taking Security+?
CompTIA recommends but does not require Network+ first. If you already understand OSI layers, common ports, subnetting basics, and firewall concepts, you can skip straight to Security+. If networking is new, take Network+ first or spend an extra 2 weeks on networking review.
3. What jobs can I get with Security+?
Common roles include SOC Analyst Tier 1, Junior Penetration Tester, Security Engineer, Systems Administrator with security focus, IT Auditor, and Compliance Analyst. Entry salaries in the U.S. range from 65,000 to 95,000 USD depending on location and experience.
4. How long is Security+ valid and how do I renew it?
Security+ is valid for 3 years. You can renew by earning 50 Continuing Education Units (CEUs) through approved training, higher certifications, published articles, or work experience. Most people renew by earning a higher level cert like CySA+ or CISSP, which automatically renews Security+.
5. Should I take the exam at a test center or online?
Both deliver the same content. Test centers are less stressful technically (no webcam issues, no environment checks) but require travel. Online proctored is convenient but has strict rules (no bathroom breaks, no off screen glancing, clean desk policy). Choose what fits your environment. If you are prone to tech issues, go in person.
