Cloud: Dawn of a New Age• Art Coviello - the most overhyped,

underestimated phenomenon since the Internet • Compute as a utility• Changes everything: business models, venture

capital, R&D, ……

http://www.cloudsecurityalliance.org/


What is Cloud Computing?• Compute as a utility: third major era of computing

• Cloud enabled by• Moore’s Law

• Hyperconnectivity

• SOA

• Provider scale

• Key characteristics• Elastic & on-demand

• Multi-tenancy

• Metered service

2010-2013: the Hybrid Enterprise

enterprise boundary

public clouds

Extended Virtual Data Center

private clouds

cloud of users

Notional organizational

boundary

• Dispersal of applications

• Dispersal of data

• Dispersal of users

• Dispersal of endpoint devices



Cloud & mobility forcing key issues• Critical mass of separation between data owners

and data processors• Anonymity of geography of data centers &

devices• Anonymity of provider• Transient provider relationships• Physical controls must be replaced by virtual

controls• Identity management has a key role to play• Cloud WILL drive change in the security status

quo• Reset button for security ecosystem



Key Cloud Security Problems of Today

From CSA Top Threats Research:• Trust: Lack of Provider transparency, impacts

Governance, Risk Management, Compliance

• Data: Leakage, Loss or Storage in unfriendly geography

• Insecure Cloud software

• Malicious use of Cloud services

• Account/Service Hijacking

• Malicious Insiders

• Cloud-specific attacks



Key Problems of Tomorrow

•Globally compatible legislation and policy

•Compatible Private & Public clouds•Real-time Risk Mgt & Compliance•Identity Management•Responding to security incidents



About the Cloud Security Alliance• Global, not-for-profit organization• Over 16,500 individual members, 90 corporate

members• Building best practices and a trusted cloud

ecosystem• Agile philosophy, rapid development of applied

research• GRC: Balance compliance with risk management• Reference models: build using existing standards• Identity: a key foundation of a functioning cloud

economy• Champion interoperability• Advocacy of prudent public policy

“To promote the use of best practices for providing security assurance within Cloud Computing, and provide education on the uses of Cloud

Computing to help secure all other forms of computing.”

• Popular best practices for securing cloud computing

• V2.1 released 12/2009

• V3 target Q3 2011

• wiki.cloudsecurityalliance.org/guidance


http://cloudsecurityalliance.org/guidance


Securing the Cloud - Governance• Best opportunity to secure cloud engagement

is before procurement – contracts, SLAs, architecture

• Know provider’s third parties, BCM/DR, financial viability, employee vetting

• Identify data location when possible

• Plan for provider termination & return of assets

• Preserve right to audit

• Reinvest provider cost savings into due diligence



Securing the Cloud - Operating• Encrypt data when possible, segregate key

mgt from cloud provider

• Adapt secure software development lifecycle

• Understand provider’s patching, provisioning, protection

• Logging, data exfiltration, granular customer segregation

• Hardened VM images

• Assess provider IdM integration, e.g. SAML, OpenID



Cloud Controls Matrix Tool• Controls derived from

guidance

• Rated as applicable to S-P-I

• Customer vs Provider role

• Mapped to ISO 27001, COBIT, PCI, HIPAA

• Help bridge the gap for IT & IT auditors



Consensus Assessment Initiative

• Research tools and processes to perform shared assessments of cloud providers

• Lightweight “common 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



CloudAudit

• Open standard and API to automate provider audit assertions

• Change audit from data gathering to data analysis

• Necessary to provide audit & assurance at the scale demanded by cloud providers

• Uses Cloud Controls Matrix as controls namespace

• Now a CSA project! www.cloudaudit.org


http://www.cloudaudit.org/


CSA GRC Stack• Suite of tools, best practices and enabling technology

• Consolidate industry research & simplify GRC in the cloud

• For cloud providers, enterprises, solution providers and audit/compliance

• Controls Framework, Questionnaire and Continuous Controls Monitoring Automation

The need for the Security as a Service Initiative

• Information assurance challenged by disruptive trends (cloud, mobility, social networking, etc)

• Cloud provides opportunity to rethink security (economics, architecture, service delivery models, etc)

“To promote the use of best practices for providing security assurance within Cloud Computing, and

provide education on the uses of Cloud Computing to help secure all other forms of

computing.”



Security as a Service Scope

• Information Security Industry Re-invented• Define Security as a Service• Articulate solution categories within Security

as a Service• Guidance for adoption of Security as a Service• Align with other CSA research

• Develop deliverables as a proposed 14th domain within CSA Guidance version 3.
