Cloud ComputingNIST Definition
• UPDATED (Jan 2011) – National Institute of Standards and Technology (NIST) Special Publication 800-145 (Draft)
• Model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services)
• Rapidly provisioned and released with minimal management effort or service provider interaction
• Composed of 5 essential characteristics, 3 service models, and 4 deployment models.

Cloud Computing5 Essential Characteristics
• On-demand tenant self-service model for provisioning computing capabilities (server time, network storage, etc.)
• Broad network access with capabilities over the network accessible by standard mechanisms and mobile platforms
• Resource pooling through dynamically assigned physical and virtual capabilities delivered in a multi-tenant model and location independent
• Rapid elasticity of provisioned resources automatically or manually adjusted aligned with service level flexibility and needs
• Measured service to monitor, control and report on transparent resource optimization

Cloud Computing3 Service Models• Software as a Service (SaaS)
• Capability made available to tenant (or consumer) to use provider’s applications running on cloud infrastructure, accessible via web browser, mobile apps, and system interfaces.
• Examples: Salesforce.com, Drop Box, Box.net, Google Docs, WebEx
• Platform as a Service (PaaS)
• Capability made available to tenant to deploy tenant owned (created or acquired) applications using programming languages and tools supported by provider.
• Examples: Microsoft Azure, Amazon Web Services, Bungee Connect
• Infrastructure as a Service (IaaS) / Datacenter as a Service (DaaS)
• Capability made available to tenant to provision processing, storage, networks or other fundamental computing resources to host and run tenant’s applications.
• Examples: Rackspace, Terremark (Verizon), Savvis, AT&T

Consensus Assessment Initiative• Research tools and processes to
perform shared assessments of cloud providers
• Lightweight “common assessment criteria” concept
• Integrated with Controls Matrix
• Ver 1 CAI Questionnaire released Oct 2010, approx 140 provider questions to identify presence of security controls or practices

Consensus Assessment InitiativeApproach
• Build “cloud-specific” question-set
• CSA guidance
• Industry experts
• Align questions with the CSA Cloud Controls Matrix
• Release 1.0 question-set publically
• Integrate into CloudAudit.org framework
• Post to CloudSecurityAlliance.org

CloudAudit
www.cloudsecurityalliance.orgCopyright © 2011 Cloud Security Alliance
CloudAudit
• Provide a common interface and namespace that allows cloud computing providers to automate the Audit, Assertion, Assessment, and Assurance (A6) of their environments
• Allow authorized consumers of services to do likewise via an open, extensible and secure interface and methodology.
www.cloudsecurityalliance.orgCopyright © 2011 Cloud Security Alliance
CloudAuditObjective• A structure for organizing assertions and
supporting documentation for specific controls across different compliance frameworks in a way that simplifies discovery by humans and tools.
• Define a namespace that can support diverse frameworks
• Express five critical compliance frameworks in that namespace
• Define the mechanisms for requesting and responding to queries relating to specific controls
• Integrate with portals and AAA systems
www.cloudsecurityalliance.orgCopyright © 2011 Cloud Security Alliance
CloudAuditAligned to Cloud Controls Matrix• First efforts aligned to compliance frameworks as
established by CSA Control Matrix:
• PCI DSS
• HIPAA
• COBIT
• ISO/IEC 27001-2005
• NISTSP800-53
• Incorporate CSA’s CAI and additional CompliancePacks
• Expand alignment to “infrastructure” and “operations”

• Index.html is for dumb browser consumptions
• Typically, the direct human user use case
• It can be omitted if directory browsing is enabled
• It contains JavaScript to look for the manifest.xml file, parse it, and display it as HTML.
• If no manifest.xml exists, it should list the directory contents relevant to the control in question

www.cloudsecurityalliance.orgCopyright © 2011 Cloud Security Alliance
CSA GRC Stack• Whether implementing private, public or hybrid clouds, the shift to
compute as a service presents new challenges across the spectrum of Governance, Risk Management and Compliance (GRC) requirements – success dependent upon:
• Appropriate assessment criteria; and
• Relevant control objectives and timely access to necessary supporting data.
• CSA GRC Stack provides a toolkit for enterprises, cloud providers, security solution providers, IT auditors and other key stakeholders to instrument and assess both private and public clouds against industry established best practices, standards and critical compliance requirements.
• Integrated suite of 3 CSA initiatives: CloudAudit, Cloud Controls Matrix (CCM) and Consensus Assessments Initiative Questionnaire (CAIQ).
