Training course
This is a free, self-paced reading course for CompTIA Security+ (SY0-701), the most widely held entry point into a cybersecurity career, and the credential that tells an employer you can assess a security posture, recommend and implement controls, monitor hybrid cloud and on-premises environments, and work inside the laws and policies that govern the field. It also satisfies U.S. DoD 8140 requirements for a long list of defense work roles. Read it straight through, in order, before you start drilling practice questions, so that a missed item becomes a gap you can name rather than a definition you half-recognize.
The course is organized as one module per official exam domain, in the order CompTIA publishes them, and each module carries the domain’s published weight. Security+ is lopsided in a way that catches people out, and following the weighting fixes it. Security Operations alone is 28% of the exam, and Security Program Management and Oversight is another 20%, governance material that technical candidates tend to skim and then lose easy points on. General Security Concepts is only 12%, but its vocabulary turns up inside questions in every other domain, which is why it comes first here.
What the course covers
General Security Concepts
Module 1 · 12%The vocabulary and mental models everything else builds on: categories of security controls, the CIA triad and non-repudiation, Zero Trust principles, the role change management plays in security, and foundational cryptography from key management through hashing. Small in weight, large in reach, these ideas reappear inside questions across every other domain.
Threats, Vulnerabilities, and Mitigations
Module 2 · 22%Know your adversary. Threat actors and their motivations; attack techniques from phishing and business email compromise through injection attacks, malware families, and password attacks; the common vulnerability classes; and how to choose the mitigation that actually addresses the scenario in front of you rather than the one that sounds strongest.
Security Architecture
Module 3 · 18%Building environments that are defensible by design: comparing cloud, hybrid, virtualized, and industrial-control architectures; network design elements including segmentation, screened subnets, and secure remote access; protecting data across its states and jurisdictions; and the resilience patterns (clustering, backups, recovery sites) that keep a business running through failure.
Security Operations
Module 4 · 28%The largest domain, and the day job: hardening and baselining systems, securing wireless and mobile fleets, vulnerability management and alerting, identity and access management from SSO through just-in-time privilege, automation, and the incident response lifecycle including forensics fundamentals. Expect scenario questions that read like tickets from a real SOC queue.
Security Program Management and Oversight
Module 5 · 20%The governance layer: policies and standards, risk management from registers through quantitative analysis, third-party and vendor risk, compliance and privacy obligations, audits and penetration-test concepts, and building a security-awareness program. This is where technical practitioners most often lose points they could have banked.
How to use it
Read a module, then test that domain immediately rather than waiting until you have covered everything. The free Security+ sample questions are the quickest way to check whether a module landed, and the full-length blueprint-weighted mock sits on the SY0-701 certification guide alongside the exam logistics, question count, timing, and the 750 / 900 scaled cut score. Reading the course itself requires a free Certifym account.
Be honest about module 5. Governance reads like the least interesting fifth of the syllabus and is the one candidates postpone, but at 20% it is worth more than Security Architecture and nearly twice General Security Concepts, and it is the easiest domain to score well in because the answers are definitional rather than situational. Read it early rather than last. Elsewhere, work scenarios rather than definitions: SY0-701 mixes performance-based questions that drop you into a simulated task with multiple-choice items that describe an incident and ask what you do next, and neither rewards recall on its own.
What Security+ Is
Security+ is CompTIA's foundational security certification. It sits at the entry point of a security career: broad enough to touch nearly every area of practical security, deep enough to filter people who have actually done the work from people who have only read about it. The current exam is SY0-701, released in late 2023, and it is what this course prepares you for.
Who Security+ is for
- IT professionals with one to two years of general IT experience moving into security roles.
- Junior security analysts building formal credentials for the resume.
- Military and defense contractors satisfying DoD 8570 / 8140 baseline requirements.
- Career changers using Security+ as their first structured proof of security knowledge.
What Security+ measures
Security+ is deliberately practitioner-oriented. It does not test whether you can architect a national security program or defend a policy in front of a board. It tests whether you can recognize attacks, apply controls, and respond when something goes wrong. The exam voice is close to what a junior-to-mid analyst would use in daily work.
Exam format
- Up to 90 questions.
- 90-minute time limit.
- Multiple choice and performance-based questions (PBQs) that ask you to configure or interpret something in a simulated environment.
- Scaled score of 750 (out of 900) to pass.
- Cost around $404 USD.
- Valid for three years, renewable through continuing education.
The five domains
- General Security Concepts — 12%.
- Threats, Vulnerabilities, and Mitigations — 22%.
- Security Architecture — 18%.
- Security Operations — 28%.
- Security Program Management and Oversight — 20%.
How this course is organized
This course maps one module to each domain, in the same order as the exam blueprint, with lessons proportional to the domain weights. Module 4 (Security Operations) is the largest because it is where the exam concentrates. Module 1 (General Concepts) is the smallest but foundational; the vocabulary introduced here recurs in every later module.
What sets Security+ apart from adjacent certifications
- Broader than Network+ (which is networking with a security seasoning).
- More technical than ITF+ or Cloud Essentials.
- Less specialized than CySA+ (analyst), PenTest+ (offensive), or CASP+/SecurityX (advanced).
- More vendor-neutral than SC-100 (Microsoft) or AWS Security Specialty.
How to think about the exam
Security+ questions frequently give you a scenario and ask what to do next, or what tool best fits, or which control most closely addresses the described risk. The wrong answers are usually plausible; the right answer is often the most direct match to the exact wording of the scenario. Reading carefully wins more points than knowing more facts.
What comes after Security+
- Specialization: CySA+ (analyst), PenTest+ (offensive), CCSP (cloud security).
- Advancement: CISSP, CISM, SecurityX (formerly CASP+).
- Role progression: junior analyst → SOC analyst → senior analyst → security engineer.
This first lesson is a free preview so you can sample the depth and voice. The remaining 49 lessons continue in the same practical register.
Frequently asked questions about the Security+ training course
Is the Security+ training course free?
Yes. The course costs nothing to read; it is behind a free Certifym account, with no payment and no card. It is funded by the same practice-exam catalog it sits alongside.
How is the course structured?
One module per official SY0-701 exam domain, in CompTIA’s published order, with each module weighted to the domain’s published percentage: 12%, 22%, 18%, 28%, and 20%. Within each module the material is broken into short lessons, followed by key terms and further reading.
Does this replace CompTIA’s official training?
No. CompTIA publishes the authoritative SY0-701 exam objectives along with its own CertMaster courseware, and those are the reference of record. This course is an independent study companion, written to be read quickly and to slot alongside practice questions.
Do I need Network+ before starting?
There is no enforced prerequisite, but Security+ quietly assumes networking fluency, the Security Architecture module in particular expects you to already understand segmentation, subnets, and remote access. Network+ is the usual step before it. If your networking is shaky, work through the Network+ course first rather than trying to learn both at once.
What should I do after finishing the course?
Move to blueprint-weighted practice questions and keep going until you are clearing the bar consistently across all five domains rather than riding a strong Security Operations score. After the exam, CySA+ is the analyst-level credential further along the same path.
Is the course current, and what about SY0-801?
The course is built against SY0-701, released by CompTIA in November 2023 and still the current exam. CompTIA refreshes Security+ on a roughly three-year cycle, and a successor, SY0-801, is expected to begin rolling out in late 2026, with SY0-701 remaining available for a transition period after that.
