The Cloud Buzz word Overused cliché Ill defined Many different definitions Marketing term All hype The unknown path Service provider 8 Nebulous

9..[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.

10 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

11 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)

13 Based on agency estimates as reported to the Office of Management and Budget (OMB) Federal Cloud Computing Strategy

14 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

15 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)

16 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

21 Wheres My Data? The Bad Divorce Trust but Verify I thought you knew I didnt think of that Clarify Consider Expectations, Put it in Writing

22 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)

23 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

24 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 Certification Audit / Assessment

25 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

26 Dependencies Infrastructure – Internet Authentication management (SSO) Operational budget Greater dependency on 3 rd parties Other considerations Complex legal issues Multi-tenancy Transborder data flow

27 What do they mean by Cloud Establish clear responsibilities and accountability Your expectations Cost of compensating controls What will happen with billing disputes

28 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

29 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
