    Study Notes

    Cloud Security and Governance

    • Cloud computing is a shared model, with different entities responsible for different parts of the stack.
    • Security responsibilities are divided between Cloud Service Providers (CSPs) and Cloud Service Consumers (CSCs).
    • CSPs secure infrastructure, hardware, and network, while CSCs secure their applications and data.
    • This division of responsibilities varies based on the service model (IaaS, PaaS, SaaS), and between different CSPs.

    Cloud Service Models

    • Infrastructure as a Service (IaaS):

      • The foundation is physical hardware, networks, and storage.
      • Resources are pooled through abstraction (often virtualization) and orchestration.
      • Orchestration uses APIs (primarily REST over HTTP for remote access and web-based interfaces).
      • Management interfaces are crucial, offering control over cloud resources.
      • Security differs from on-premises infrastructure due to networked access. Attacking management interfaces gives privileged access to cloud infrastructure.
      • CSPs secure the underlying infrastructure; CSCs secure their virtualized elements, OS and apps.

    • Platform as a Service (PaaS):

      • CSPs manage platform security.
      • CSCs manage their implementations within the platform, including configuring security features.
      • More even split of responsibility than IaaS.
      • Example: Database as a Service (DBaaS). CSPs manage core configuration; CSCs manage database security features, user accounts, and authentication.

    • Software as a Service (SaaS):

      • CSPs manage most security aspects, as CSCs primarily manage their application use.
      • CSCs manage access controls, entitlements, and permissions within the application.
      • CSPs secure perimeter, logging, monitoring, and application security, while CSCs retain some element of control.

    • Anything as a Service (XaaS):

      • A wide umbrella term for various services delivered via the internet.
      • A generic term that covers various service types above the PaaS, IaaS, and even SaaS models.

    Shared Security Responsibility Model

    • Security is a joint effort between CSPs and CSCs.
    • CSPs are responsible for the cloud's security infrastructure.
    • CSCs are responsible for their deployed applications and data within the cloud environment.
    • Responsibilities vary among service models.

    Cloud Governance Implementation Models

    • Cloud Center of Excellence (CCoE) and Cloud Advisory Council (CAC) are standard approaches.
    • CCoE: A centralized team to guide, standardize, and support cloud adoption. Align with business objectives, establish policies, manage risks, enforce compliance, and disseminate knowledge. It focuses on security as a key function.
    • CAC: A senior executive group that establishes vision and direction for cloud strategy. Their role is in the overall setting of the CSC's cloud mission and goals.
