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.
