Week 14.0 Secure Cloud Network Architecture

Overview

This module explores the core principles of cloud computing and modern enterprise security architectures, focusing on how technology, responsibility, and trust are managed in connected environments. Learners gain an understanding of cloud deployment and service models, virtualization technologies, cloud security practices, and the shift toward Zero Trust security frameworks used in today’s digital infrastructures. Cloud Deployment Models: The course examines Public, Private, Community, and Hybrid Clouds, exploring their implications for cost, scalability, and security. Cloud Service Models: Students learn about PaaS, Iaas, and SaaS, forming the XaaS ecosystem for on-demand IT delivery. Responsibility Matrix: The Shared Responsibility Model makes the security responsibilities of the customer and cloud provider clear, essential for proper risk management and compliance. Centralized and Decentralized Computing: Learners compare centralized systems offering control and simplicity with decentralized ones that enhance resilience and performance. Application and Container Virtualization: Students explore virtualization methods like Docker, which enable portability, scalability, and efficiency in cloud environments. Cloud Architecture and Features: Cloud systems are designed for scalability, elasticity, automation, and self-service provisioning. These architectural features enhance performance and adaptability. Cloud Security Considerations: The course covers data protection, encryption, identity management, and compliance.. Embedded and Industrial Control Systems (ICS): This section discusses embedded devices, IoT, and SCADA systems, focusing on their unique operational and security challenges. Deperimeterization and Zero Trust: With the fading of network boundaries, organizations adopt the Zero Trust model built on “never trust, always verify.” Zero Trust Security Concepts: Principles such as least privilege, micro-segmentation, and continuous authentication are explored to mitigate risks and ensure secure access control. Accounts Management: This section emphasizes proper account provisioning, access review, and privilege management to support Zero Trust security. By completing this module, learners understand cloud computing principles, shared responsibility, and Zero Trust concepts, enabling them to design secure cloud architectures and apply robust access management across environments.
