Chapter: Security Architecture 5514 10409
This lesson introduces security architecture models, which describe how computing systems are structured and secured across different environments. It explains how organizations design and protect infrastructure in on-premises data centers, cloud platforms, virtualized systems, IoT environments, industrial control systems (ICS), and automated infrastructure using Infrastructure as Code (IaC). Instead, they operate hybrid environments that require different security controls, trust boundaries, and risk considerations.
By the end of this lesson, you should be able:
- Understand on-premises architecture and its security model
- Compare cloud service models and deployment types
- Explain virtualization components including hypervisors and containers
- Describe IoT and ICS/SCADA environments and their risks
- Understand Infrastructure as Code (IaC) and automation security principles
Architecture Models
An architecture model is the overall design that describes how an organization's computing resources, such as servers, storage, networks, and applications, are arranged, hosted, and connected. In simple terms, it is the blueprint for where systems live and how they fit together. Just as a building can be designed in many ways, computing environments can be built using different models, each suited to different needs.
