Cloud ComputingRisks and Rewards“Cloudy with a chance of rain” Image: NASA
Cloud Computing? • The “Cloud” • Buzz word • Overused cliché • Ill defined • Many different definitions • Marketing term • All hype • The “unknown path” • Service provider Nebulous
What is it? “..[a] model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications, services) that can be provisioned and released with minimal management effort or service provider interactions.” NIST & Cloud Security Alliance A utility model of technology delivery.
Cloud Flavors • Private Cloud • Operated solely for one organization • In-sourcing • Community Cloud • Operated for a group of similar organizations • Public Cloud • Outsourced • Multi-tenant • Hybrid Cloud • Combination of the above
…as-a-service • Communication-as-a-Service (CaaS) • Infrastructure-as-a-Service (IaaS) • Monitoring-as-a-Service (MaaS) • Platform-as-a-Service (PaaS) • Software-as-a-Service (SaaS) • Security-as-a-Service (SECaaS) • Everything-as-a-Service (EaaS) • Anything-as-a-Service (XaaS)
Potential Spending on Cloud Computing Federal Cloud Computing Strategy Based on agency estimates as reported to the Office of Management and Budget (OMB)
Federal Cloud Computing Strategy “Cloud First policy. This policy is intended to accelerate the pace at which the government will realize the value of cloud computing by requiring agencies to evaluate safe, secure cloud computing options before making any new investments.” “…to be more efficient, agile, and innovative through more effective use of IT investments…” Federal Cloud Computing Strategy, February 2011
Benefits of Cloud Computing • Save time and money on provisioning new services • Less time spent on deployment • Move capital investment to operational expenses • Instant test bed • Enables IT systems to be scalable and elastic • Provision computing resources as required, on-demand • No need to own data center infrastructure (for public cloud service)
Benefits of Cloud Computing • Energy saving (green) • Increased utilization, less idle time • Cost based on usage • More effective use of capital resources ($) • Better service • Allows IT staff to focus on core competencies • Repurpose IT staff for more customer service • Outsource to esoteric experts • 24/7 service and support • Economies of scale
Federal Cloud Computing Benefits Federal Cloud Computing Strategy, February 2011
Cost Benefit Analysis Cloud Costs Cost per user Cost by bandwidth/storage Cost increase over time Cost of additional services Legal consultation costs Staff costs Training Cloud limitations Users Bandwidth Storage Service Support Dependencies Traditional Costs Hardware (initial) Software (initial) Hardware repair/upgrades Software upgrades Staff costs Energy costs Training Traditional Limits Maximum load Maximum up-time Maximum users MTTR Dependencies
Cost Benefit Analysis Example Cloud Costs TCO $22,850 Traditional Costs TCO $21,000

Cloud Risks Where’s My Data? The Bad Divorce Trust but Verify “I thought you knew” I didn’t think of that Clarify Consider Expectations, Put it in Writing
Where’s My Data? • In the information age your key asset is information. • Some information requires protection • (Credit Card Data, Student Records, SSN, etc…) • Your information could be anywhere in the world • You may loss access to your data • ISP failure • Service provider failure • Failure to pay (service provider stops access)
The Bad Divorce • “Vendor Lock” • All relationships come to an end • Let you down, had a breach, SLA performance etc… • The company fails/gets sold • Introductory pricing or it goes up over time • Transition to new vendor or in-source • How will you get your data back? • Get a prenup – get it in the contract up front
Trust but Verify • Assurance • How do you know they are protecting your data? • Not everyone is treated the same by service providers • Disclosure concerning security posture • 3rd party independent verification (audit/assessment) • SAS 70 / SSAE 16 • SysTrust / WebTrust • ISO 27001 Certification • Audit / Assessment
“I thought you knew” • Breach Notification • When do you want to know about a data breach? • (Data that you are legal obligated to protect) • Typical contracts give wide latitude for service providers • Actual verses possible breach • Timeliness of notification
I didn’t think of that • Dependencies • Infrastructure – Internet • Authentication management (SSO) • Operational budget • Greater dependency on 3rd parties • Other considerations • Complex legal issues • Multi-tenancy • Transborder data flow
Clarify • What do they mean by “Cloud” • Establish clear responsibilities and accountability • Your expectations • Cost of compensating controls • What will happen with billing disputes
Consider • The reputation of the service provider • Track record of issues • Large or small, likelihood of change • Vendor ‘supply chain management’ issues • The reliability of the service or technology • Is the technology time tested • Typically you have no control over upgrades and changes • Training for staff
Expectations, Put it in Writing • Anything they guarantee get in writing • Typical agreements are in favor of the service provider • Protect your interests in writing (have legal look at it) • Get specific SLA • Document specific security requirements • Non-performance clause • Disposition and transition clauses • Notification requirements
Resources • Cloud Security Alliance • cloudsecurityalliance.org • ISACA: Cloud Computing Management Audit/Assurance Program, 2010 • NIST Special Publication 800-145 (draft) • Federal Cloud Computing Strategy, February 2011 • Above the Clouds managing Risk in the World of Cloud Computing by McDonald (978-1-84928-031-0) • Cloud Computing, Implementation, Management, and Security by Rittinghouse and Ransome (978-1-4398-0680-7)
