The information security certification landscape is genuinely confusing for beginners — not because the field is hard to enter, but because most course recommendations skip the step where they explain what level you're actually at. CISSP requires five years of paid work experience. CISM targets managers. Jumping straight to either one is like trying to learn to drive on a highway.
This guide covers the best information security courses for beginners based on where you're actually starting from, what skills employers look for at the entry level, and how to sequence your learning so you're not wasting months on the wrong material.
What Information Security Actually Covers
Information security (infosec) is the practice of protecting data from unauthorized access, disclosure, alteration, and destruction. It's related to — but not identical to — cybersecurity. Cybersecurity focuses specifically on digital systems and networks; information security includes physical security, policy, and governance as well. In job postings, employers use the terms interchangeably, so don't get stuck on the distinction.
At the beginner level, the field breaks into a few main areas:
- Technical security: Firewalls, encryption, access control, network monitoring, vulnerability scanning
- Security operations: Incident response, threat detection, log analysis — this is SOC analyst work
- Governance, risk, and compliance (GRC): Policies, audits, and frameworks like ISO 27001 and NIST
- Security engineering: Secure software development, application security testing
Most entry-level roles sit in technical security or security operations. GRC roles often require some professional background first, even if not specifically in security. Knowing which lane you're aiming for affects which courses are actually worth your time.
Where Information Security Beginners Should Start
Before picking a course, it's worth understanding the sequence most practitioners actually follow — because the industry has a clear progression that's worth respecting.
- Build IT fundamentals first. Understanding how networks work, what operating systems do, and how hardware and software interact is not optional. You cannot secure something you don't understand. This is where most beginners skip a step and regret it later.
- Get a foundational security certification. CompTIA Security+ is the most widely recognized entry-level credential. It's vendor-neutral and required by name for roles under DoD 8570. The Google Cybersecurity Certificate is more accessible but carries less employer weight.
- Choose a specialization track. After Security+, paths diverge: SOC work, penetration testing, cloud security, and GRC each have their own certifications and skill requirements.
- Build demonstrable experience. Labs, CTF competitions, home networks, and TryHackMe/Hack The Box for technical tracks. A certificate alone doesn't get you hired — employers want evidence you can apply the knowledge.
The courses below map to the first two steps of that sequence. Where a course fits a later step, that's noted explicitly.
Best Information Security Courses for Beginners
These recommendations include a direct statement of who each course is actually for, because "great for beginners" is meaningless without context.
Information Technology Essentials
The right starting point if you don't yet have an IT background. This Udemy course (rated 9.2) covers the foundational concepts — networking, hardware, operating systems, and basic security principles — that every information security beginner needs before tackling anything more specific. If you're coming from a non-technical background, treat this as prerequisite material, not optional.
Information Systems Auditing, Controls and Assurance
This Coursera course (rated 9.7) covers how organizations identify, assess, and control information security risks — the governance and controls layer that's systematically underrepresented in beginner resources. It's a strong follow-on once you have IT fundamentals in place and want to understand how security frameworks and audit processes function in actual organizations.
CISM®-Aligned 2026 – Information Security Manager Training
This Udemy course (rated 9.4) is technically aimed at practitioners pursuing the CISM certification, but it gives beginners a clear structural view of enterprise information security: how governance works, how risk is managed at the organizational level, and how incident response programs are built. Use it to understand the full scope of the field and plan a career trajectory — not as your first credential to chase.
Certified Information Systems Security Professional (CISSP) – Seventh Edition
The CISSP is the senior practitioner's credential and this Coursera course (rated 8.7) maps directly to its eight exam domains. It's included here not as a beginner course, but because understanding what CISSP covers tells you exactly where advanced information security work ends up — useful context when you're making decisions about a multi-year career path.
Skills Employers Actually Look For at Entry Level
Course curricula can be abstract. Here's what entry-level information security practitioners are expected to demonstrate in interviews and on the job:
- Reading and interpreting network traffic using tools like Wireshark or tcpdump
- Identifying common vulnerability classes — OWASP Top 10 for application security, CVEs for system-level issues
- Configuring basic firewall rules and access control lists
- Understanding cryptographic concepts: symmetric vs. asymmetric encryption, hashing, public key infrastructure
- Handling basic incident response steps: isolation, evidence preservation, documentation, escalation
- Applying security frameworks: NIST Cybersecurity Framework, CIS Controls, ISO 27001 at a conceptual level
- Writing clear incident reports and policy summaries — GRC roles especially require this
No single course covers all of these. The IT Essentials course handles the conceptual foundation. The auditing and controls course teaches the framework and governance layer. Hands-on labs and practical exercises — outside of any course — are where technical skills actually solidify.
Certifications Worth Knowing About
Courses and certifications are different things. A course delivers content; a certification is an exam result that employers recognize on a resume. Here's where beginners should focus and what to avoid:
- CompTIA Security+: The standard entry-level cert. No experience requirement. Covers cryptography, network security, identity management, and threat analysis. Widely recognized and specifically listed in many job postings.
- ISC2 Certified in Cybersecurity (CC): A newer, free entry-level certification from the same organization that issues CISSP. Low barrier to entry and increasingly recognized by employers as a stepping stone.
- Google Cybersecurity Certificate: More accessible than Security+ but carries less employer weight. Good for initial orientation, not a substitute for Security+ if you want to compete for technical roles.
- CISM: Requires five years of information security work experience, with at least three in management. Not a beginner credential.
- CISSP: Requires five years of full-time paid experience in at least two of the eight CISSP domains. Endorsed by two ISC2 members is also required. A senior credential, not a starting point.
Vendors and course platforms benefit financially from selling CISM and CISSP prep to beginners. Know what you're actually eligible for before spending money on exam prep.
FAQ
Can I learn information security with no IT background?
Yes, but you need to build IT fundamentals before anything security-specific will make sense. Someone who doesn't understand how TCP/IP works or what a subnet is will struggle with network security content that assumes that knowledge. The IT Essentials course is specifically designed to fill that gap before you move into security topics.
How long does it take to get an entry-level information security job?
For someone starting from zero with consistent effort, 12–18 months is a realistic window to become competitive for roles like SOC analyst or IT security technician. That assumes working toward a recognized certification (Security+ or equivalent) and building hands-on lab experience alongside coursework. People who only complete courses and skip the practical component often take longer.
Is information security the same as cybersecurity?
Technically, information security is the broader discipline — it includes physical security, governance, and policy, not just digital systems. Cybersecurity focuses specifically on protecting digital infrastructure. In practice, employers use the terms interchangeably in job postings, so for career planning purposes you can treat them as referring to the same field.
Do I need a degree to work in information security?
No, though a degree helps at larger employers and for certain government or defense contractor roles that require security clearances. Many practitioners enter through certifications and self-study. Employers at the entry level increasingly care about demonstrated skills — certs, lab work, portfolio projects — over formal degrees, particularly for technical roles like SOC analyst or vulnerability assessment.
What's the difference between Security+ and CISSP?
The gap is substantial. CompTIA Security+ is an entry-level certification with no experience requirement. CISSP requires five years of paid work experience in at least two of its eight knowledge domains. Security+ is where you start; CISSP is where senior practitioners end up after years of working in the field. Anyone recommending CISSP as a beginner course is either uninformed or selling something.
Are information security courses enough to get hired on their own?
Rarely. Employers at the entry level want a combination: a recognized certification (typically Security+), some form of hands-on experience (labs, CTF competitions, home lab setups, or internships), and the ability to speak coherently about security concepts in an interview. Courses build the knowledge. You need somewhere to apply it that you can point to in a conversation.
Bottom Line
If you're starting from scratch, the right sequence is: build IT fundamentals, understand how information security fits into organizational risk management, then work toward a recognized entry-level certification like Security+.
The Information Technology Essentials course handles step one for non-technical beginners. The Information Systems Auditing, Controls and Assurance course is the right follow-on once you have that foundation — it covers the controls and governance layer that most entry-level roles expect you to understand.
Don't start with CISM or CISSP prep. Both assume professional experience you won't have yet, and neither is an entry-level credential regardless of how course platforms market them. Know where you are in the sequence, pick the course that fits that step, and build hands-on experience in parallel with your coursework.
