1. **Compute:** At the core is the Hypervisor (Type 1 or Type 2), which abstracts physical hardware (CPU/RAM) to create Virtual Machines (VMs). Modern infrastructure also includes container engines (like Docker) and orchestration platforms (Kubernetes). Security concerns here focus on isolation, preventing 'VM escape,' and ensuring 'neighbor' separation in multi-tenant environments.
2. **Networking:** Physical cabling is abstracted into Software-Defined Networking (SDN). SDN decouples the network control plane from the data plane. Key components include Virtual Private Clouds (VPCs), virtual switches, load balancers, and Security Groups (virtual firewalls). Security relies heavily on micro-segmentation and preventing misconfigured routing.
3. **Storage:** Storage is abstracted into three main types: Block (virtual hard drives), File (NAS-like), and Object (API-driven storage like S3). Security professionals must distinguish between these to apply appropriate encryption (at rest and in transit) and data sanitization techniques, such as crypto-shredding.
4. **The Management Plane:** This is the interface (Web Console and APIs) used to configure and orchestrate the compute, network, and storage layers. From a CCSP perspective, this is the most critical security component. It requires strict Identity and Access Management (IAM) and Multi-Factor Authentication (MFA), as a compromise here grants total control over the virtual infrastructure.
Cloud Infrastructure Components: A Comprehensive CCSP Guide
What are Cloud Infrastructure Components? Cloud infrastructure components are the foundational elements—hardware and software—that create the cloud computing environment. In the context of the CCSP and cloud security, these are broken down into the physical layer and the abstraction layer that provides services to customers. The core components include:
1. Compute: The CPU and memory resources, usually delivered via Virtual Machines (VMs) or containers running on a hypervisor. 2. Storage: The distinct storage architectures, including Volume (Block), Object, and Database storage. 3. Network: Physical cabling and routers abstracted into Software Defined Networking (SDN) components like Virtual Private Clouds (VPCs) and load balancers. 4. The Management Plane: The interface (Web Console/API) used to configure, provision, and monitor the other components.
Why is this Important? Understanding infrastructure components is vital because security responsibilities differ based on the component's nature. In a public cloud, the provider (CSP) secures the physical component (the racks, power, and physical servers), while the customer must secure the configuration of the logical components (firewall rules, OS patching, encryption). Furthermore, the breakdown of these components introduces specific threats, such as VM Escape (attacking the hypervisor from a VM) or Side-Channel Attacks (gleaning data from shared hardware caches).
How it Works Cloud infrastructure operates through Virtualization and Orchestration. The physical hardware serves as a massive resource pool. The Hypervisor (or VMM) abstracts this hardware, ensuring that one tenant's VM believes it has dedicated hardware, even though it is sharing a CPU with a competitor's VM. The Management Plane orchestrates this by receiving API calls (e.g., 'Create new Server') and instructing the hypervisor to allocate the necessary physical resources logically.
Exam Tips: Answering Questions on Cloud Infrastructure Components When answering CCSP questions about this topic, apply the following logic:
1. Protect the Management Plane: This is the most cited vulnerability in cloud infrastructure. If a question asks about the highest priority for securing the cloud infrastructure, look for answers related to securing the management plane (MFA, API keys, restricted access logic). It is the 'master key' to the environment.
2. TPM vs. HSM: Distinguish between these hardware components. Trusted Platform Module (TPM): A chip on the motherboard used for Validated Boot and establishing a hardware Root of Trust. Hardware Security Module (HSM): A dedicated appliance used for high-security cryptographic key generation and management. If the question asks about managing keys securely, the answer is HSM.
3. Isolation is Logical, Not Physical: In a multi-tenant environment, recognize that separation is logical. If an exam scenario requires absolute physical isolation, the answer points toward a Private Cloud or a Dedicated Host solution, not standard public cloud instances.
4. Software Defined Networking (SDN): Remember that in SDN, the Control Plane (intelligence) is decoupled from the Data Plane (pocket forwarding). Exam questions may focus on the risk of the Control Plane being compromised, which would allow an attacker to redirect all network traffic silently.
