ISO/IEC

What is ISO/IEC Information Security?

ISO/IEC is the joint technical committee of the International Organization for Standardization and the International Electrotechnical Commission. Together they publish the world’s most widely adopted information security management standards — used by organizations in every industry across 160+ countries. ISO describes the 27000 family:

The ISO/IEC 27000 family of standards helps organizations keep information assets secure. Using this family will help your organization manage the security of assets such as financial information, intellectual property, employee details, or information entrusted to you by third parties.

For security professionals, ISO certifications validate the governance, risk, and compliance skills that technical certifications like OSCP and Security+ don’t cover. Organizations implementing ISO 27001 hire specifically for Lead Implementers and Lead Auditors. CISO-track professionals need this framework.

Is This Right for You?

This is for you if...

You’re targeting GRC (Governance, Risk, Compliance) roles or CISO-track positions
You need to implement or audit an Information Security Management System (ISMS)
Your organization is pursuing ISO 27001 certification and needs qualified practitioners
You want to complement technical certifications (Security+, CISSP) with governance expertise
You’re in a region or industry where ISO 27001 compliance is a regulatory requirement

This is NOT for you if...

You’re looking for hands-on technical security skills — CompTIA, OSCP, or Blue Team paths serve that
You’re early in your career with no security or business experience — ISO roles require context
You want certifications that expire never — ISO credentials require recertification cycles

How to Get Started

Read ISO 27001:2022 before taking any course. The standard itself is 30 pages. Buy it from iso.org or read a certified summary. Before paying for Lead Implementer training, know what clauses 4–10 say.
Map a real organization’s posture to Annex A controls. Take any organization you know and work through the 93 controls. Which exist? Which are missing? This gap analysis exercise teaches ISO 27001 faster than any course.
Choose your track: Implementer or Auditor. Implementers build ISMS programs inside organizations. Auditors assess whether programs meet the standard. Pick based on whether you want to build or assess.

Introduction: **In our first guide**, we covered how to start learning cybersecurity without feeling overwhelmed. If you haven’t read it yet, start there. Now, let’s talk about which path to take once you’re ready. When I decided to get into cybersecurity 20 years ago after I graduated from school of engineering as computer engineer, I had no idea which path to take. I bought a CEH course first. Then I bought a Security+ book. Then I tried to learn networking. I was all over the place. Don’t be me.

Introduction: The Overwhelm is Real (But Avoidable) Let’s be honest with ourselves to avoid the shock and be realistic. Cyber security is huge, branching, and massive field. When I decided to get and start in this field 20 years ago. I made every mistake imaginable: Bought expensive courses I never finished. Tried to learn everything at once – pentesting, malware analysis, cloud security, forensics. All in short time. Got trapped in “tutorial”- watching videos for hours but never actually doing anything because of not practicing them and being confused.
