When I started working in cybersecurity, most systems were on-premise. We knew where physically the servers were, who had the ownership, and a proper escalation matrix. But this came at a huge initial capital investment, i.e., networking gear, data center space, power, cooling, etc. Today, the cloud service providers like AWS, Azure, and Google Cloud changed the rules of the game by bringing down that cost as companies moved to a pay-as-you-go model.
What is a cloud?
The cloud is like a rented car; instead of having to buy your own, you pay for what you use. Earlier, our photos used to be saved only on our phone; today they are saved on Google Drive and iCloud and available on any device. So the cloud is basically someone else’s computer that you access over the internet; you pay a subscription fee for the service instead of buying your own.
The cloud service provider instead owns huge data centers full of servers.
Challenges in cloud security
- Misconfiguration of cloud resources
- Insecure access controls on cloud resources
- Data residency requirements
- Visibility and monitoring cloud environments.

CompTIA Security+ (SY0-601) Cert Prep: 6 Cloud Security Design and Implementation is clearly designed as a foundational bridge between traditional security concepts and cloud environments, especially for those preparing for the Security+ exam. From a technical standpoint, this course does a solid job of explaining how the cloud changes the security mindset. It covers core cloud computing concepts like virtualization, multitenancy, cloud service models (IaaS, PaaS, SaaS), and shared responsibility, which is critical for anyone moving from on-prem to cloud.
Mike Chapple is a well-known and highly respected cybersecurity educator with a strong academic foundation and deep subject-matter expertise. As a teaching professor at the University of Notre Dame, he brings a structured and disciplined approach to explaining cybersecurity concepts. His experience in teaching security frameworks, risk management, and certification-oriented content is clearly reflected in the way he breaks down complex topics into simple, logical explanations that are easy to follow.
Although it doesn’t go deep into vendor-specific tools like AWS IAM policies or Azure Defender, it clearly explains the “why” behind cloud security decisions, which is exactly what Security+ expects. So use this course to strengthen fundamentals, then pair it with hands-on cloud labs and real-world use cases.
Best Course for CCSP Certification Preparation (Udemy)
- Level: Beginner–Intermediate
- Rating: 4.5
- Duration: 18 Hours

This course is designed for those looking to transition into a cloud security role or preparing for the CCSP exam. The course instructor, Mbong Hudson, is a seasoned professional in the field of cloud security and networking. He holds well-known certifications like CCNP, AWS, and CISSP, which show his strong technical background.
Certified Cloud Security Professional (CCSP) covers all six CCSP domains, starting with cloud concepts and secure design like IaaS, PaaS, SaaS, shared responsibility, and multi-tenancy. It then moves into cloud data security with encryption, key management, and data lifecycle controls, followed by cloud infrastructure security such as IAM, access control, network segmentation, and securing VMs and containers.
With his real-world experience in cloud and cybersecurity, the course comprises seven sections along with quizzes and a certification of completion. What I like about the course is that it focuses on both theoretical and practical aspects of cloud security using real-world scenarios. The instructor explains complex topics in a practical and easy-to-understand way, making the course more reliable and industry-oriented.
This course is ideal for CCSP aspirants or people who already understand basic IT or cybersecurity.
Great for exams and real-world knowledge, but not best for total beginners
Best Course for Cloud Security Architecture & Shared Responsibility (LinkedIn Learning)
- Level: Intermediate
- Rating: 4.7
- Duration: 2-3 hours
- Cost: Paid (subscription)
What You’ll Learn
- Cloud service models like IaaS, PaaS, SaaS
- Shared responsibility in cloud security
- Threats and incidents that impact cloud systems
- Practical defenses like encryption, logging, and monitoring
- Security as a Service (SecaaS) capabilities
- Key controls for identity, data, and access management.
In my experience, many security issues in cloud environments don’t happen because security controls are missing, but because teams misunderstand shared responsibility and cloud architecture. Cybersecurity with Cloud Computing does a good job of addressing that gap by focusing on fundamentals rather than jumping straight into tools.
Technically, the course walks through cloud foundations from a security lens. It covers cloud service models (IaaS, PaaS, SaaS), deployment models, and the essential characteristics of cloud computing. It explains shared responsibility in practical terms, highlights risks specific to cloud environments, and introduces Security as a Service (SecaaS). There is also exposure to how major providers like AWS, Azure, and Google structure their offerings, along with core security controls such as encryption, logging, monitoring, and access control. This aligns well with how cloud security is actually approached at a design and governance level.
Best Course for Google Cloud Platform (GCP) Security (Udemy)
- Level: Beginner–Intermediate
- Rating: 4.5
- Duration: 2-3 hours
- Cost: Paid
What You’ll Learn
- Identity and Access Management (IAM) concepts and least-privilege access
- Organization policies and how security controls are enforced at scale
- Securing compute workloads and Kubernetes environments
- Network security concepts specific to GCP
- Data protection mechanisms like DLP and storage security controls.
In my experience, most security issues in cloud environments stem from misconfigured IAM, weak network controls, or poor data protection strategies, and Google Cloud Security Best Practices Crash Course directly targets those areas. So, this course is best viewed as a practical orientation into Google Cloud security, especially for professionals who already understand general cybersecurity concepts but are either new to GCP or want clarity on how Google approaches cloud security differently.
From a technical standpoint, the course sticks to core GCP security primitives, not theory. Most of the focus is on IAM service accounts, federated identity, and RBAC, which aligns with how real cloud security failures usually happen. It also covers organization policies for governance and explains how applications, APIs, and workloads should be secured using native GCP controls.
It helps you understand how Google expects security to be designed, governed, and enforced across cloud environments. I would recommend this course as a starting point or refresher, especially before hands-on labs or certification prep. Pair it with practical GCP labs and real IAM/network hardening exercises, and it becomes a solid stepping stone toward working confidently in Google Cloud security environments.
Best Course for Enterprise Cloud Security with Palo Alto Networks (Coursera)

In my infosec career, I have extensively worked with Palo Alto’s tech stack, like the firewall, XDR, and GlobalProtect VPN. Palo Alto Networks Cloud Security Fundamentals introduces you to foundational concepts of cloud security. You start by understanding cloud computing models, shared responsibility, and deployment types, then move into core technologies like virtual machines, containers, and serverless computing. What I like most about this course is that it just doesn’t explain theory, but also includes hands-on skills like configuring containers and performing vulnerability scans. Additionally, you get exposure to securing the cloud, especially in hybrid setups.
This cloud security course is best suited to those looking to transition into cloud security roles or working in Palo Alto environments. It won’t replace platform-specific training, but it gives a good head start.
