What is Cloud Security?
Cloud security is the fastest-growing discipline in cybersecurity. As organizations migrate to AWS, Azure, and Google Cloud Platform, the attack surface shifts — and so do the skills required to secure it. The Cloud Security Alliance defines the scope:
Cloud security encompasses the policies, controls, procedures, and technologies that work together to protect cloud-based systems, data, and infrastructure. It addresses the shared responsibility model, identity and access management, data protection, and threat detection specific to cloud environments.
NIST frames the challenge:
Cloud computing introduces unique security challenges that require organizations to understand the shared responsibility model, implement cloud-native security controls, and develop expertise in securing dynamic, scalable infrastructure.
Whether you’re on offense (cloud penetration testing), defense (cloud security architecture), or governance (compliance and risk), cloud security is where the industry is moving fastest and where the talent shortage is most acute.
Is This Right for You?
This is for you if...
- You’re working toward cloud security architect, cloud penetration tester, or DevSecOps roles
- Your organization is migrating to AWS, Azure, or GCP and needs security expertise
- You have traditional security experience and want to translate it to cloud environments
- You want the fastest-growing, highest-paying specialization in cybersecurity right now
- You’re a developer or sysadmin who wants to build security into cloud infrastructure
This is NOT for you if...
- You have no networking or security fundamentals — build those with CompTIA first
- You want one certification that covers all cloud providers — you’ll need provider-specific certs
- You’re looking for hardware or physical security skills — this path is entirely software and policy

Where to Practice
── Hands-On Practice Platforms ──
- ARMO CTRL — hands-on Kubernetes attack simulation, free
- Hack The Box — cloud-focused machines and Pro Labs
- TryHackMe — cloud security learning paths
- PortSwigger Web Security Academy — web attack surface in cloud contexts
How to Get Started
- Create a free AWS or Azure account today. Both offer free tiers. Spin up a VM, create an IAM user with wrong permissions, deploy an S3 bucket with default settings — then fix it. Seeing misconfigurations with your own hands is how cloud security becomes real.
- Complete the free CCSK training before paying for any cert. The CSA offers free CCSK study materials. Complete them before spending money on provider-specific training. The vendor-neutral foundation makes every provider cert easier.
- Do flaws.cloud before any cloud pentest cert. cloud is a free AWS CTF built around real-world misconfigurations. Working through it teaches more about cloud attack surface than most paid courses.

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.

We only recommend tools we genuinely believe in and that we consider useful for your cybersecurity learning journey. Our editorial opinions are never influenced by affiliate relationships. 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.
