Principles • Define protections that enable trust in the cloud. • Develop cross-platform capabilities and patterns for proprietary and open-source providers. • Will facilitate trusted and efficient access, administration and resiliency to the customer/consumer. • Provide direction to secure information that is protected by regulations. • The Architecture must facilitate proper and efficient governance, identification, authentication, authorization, administration and auditability. • Centralize security policy, maintenance operation and oversight functions. • Access to information must be secure yet still easy to obtain. • Delegate or Federate access control where appropriate. • Must be easy to adopt and consume, supporting the design of security patterns. • The Architecture must be elastic, flexible and resilient supporting multi-tenant, multi-landlord platforms • The Architecture must address and support multiple levels of protection, including network, operating system, and application security needs.
Goals • Use the breadth of the Cloud Security Alliance • Adjacent initiatives will be a focus for the TCI mandate • Built upon “pillars” from the Cloud Security Alliance • Provide an end-to-end security specification for cloud security • Use the depth of the Cloud Security Alliance membership • Members have credibility from the top of the application to the “bare metal” • GRC and interoperability • Enable a vendor neutral reference architecture specification • All vendor products that enable an end-to-end security platform will be used • Provide a exemplary reference set of implementations • Global examples so that any country can implement the architecture to their requirements • Show examples of standards and how they can be implemented across products • Open source initiative • Where the TCI supports implementation under its direction the implementation is open source Note: The TCI Reference Architecture is not the same as the Cloud Computing Architectural Framework (Domain 1 of the Security Guidance for Critical Areas of Focus in Cloud Computing V2.1)
