2 2 Agenda Background & Objective Current Scenario & Future of Cloud Computing Challenges in Cloud Computing Data Security, Data Privacy Compliance Legal and Contractual Challenges faced by Cloud Providers Recommendations

3 3 Background & Objective DSCI has undertaken a study on Data Protection Challenges in Cloud Computing in partnership with Wipro with the objective to understand the security and privacy challenges and trends in Cloud Computing with respect to Indian IT environment As part of this study, DSCI along with Wipro conducted a survey to understand the perception of the security professionals on risks & challenges associated with Cloud Computing focusing on Security & Privacy

4 4 Study Methodology Primary research A survey across 48 organizations Survey was conducted by DSCI and Wipro Total of 71 professionals representing 48 organizations Secondary research, covering the following aspects vis-à-vis Cloud Computing: Different Cloud deployment models (Private, Public, Hybrid etc) Cloud Services Models (SaaS, PaaS, IaaS, etc.) Current Scenario and Future of Cloud Computing Reasons behind considering Cloud Computing Challenges in the adoption of Cloud Computing Criteria for Cloud service provider selection Challenges faced by Cloud service providers Role of NASSCOM-DSCI in Cloud Computing ecosystem

5 Cloud Computing in India World Cloud Services Revenue forecasted to reach $ 68.3 billion in 2010 and $148.8 billion in 2014 Cloud Computing market in India currently stands at USD 110 million and is expected to reach USD 1,084 million by 2015* Software-as-a-Service (SaaS) has witnessed the highest growth and it is likely to reach a mark of USD 650 million by 2015* 21% of the surveyed firms are planning to host IT services on the Cloud and pilot projects are initiated Cloud adoption in India 24% 15% 38% Not considering migration to Cloud Computing as of now 5 21% Already using Cloud Computing services Planning to initiate a pilot project or implement less critical services Planning a complete migration Will consider based on the industry / peer adoption trend

6 6 Cloud Deployment models and Adoption Private cloud. - Dedicated cloud infrastructure for an org. Self Managed or Third Party, On premise / Off Premise Public cloud. - Shared Cloud Infrastructure on a cost services model selling cloud services. Hybrid cloud. Cloud infrastructure composed of private, public and or community cloud that enables data & application portability (e.g., cloud bursting). Community cloud. Shared cloud infrastructure managed by the organizations or a third party and may exist on premise or off premise ORGANISATION PREFERENCE FOR ADOPTION OF CLOUD DEPLOYMENT MODELS Deployment Decision Matrix Cost Effectiveness Management Control Reliability Accountability Standardization Adoption Security Public Cloud 6% Private Cloud 29% 66% Hybrid Cloud or Community Cloud Large enterprises points toward exploring Public Clouds for hosting of non-business, non-critical, support applications only such as Document Management Systems hosted s, CRM and Learning Solutions, etc Critical Applications, that demand data to reside within organizational systems, because of regulatory/legal requirements, remain on the Private Cloud Organizations often adopt Public Cloud for services where users are not required to deal With any sensitive data

7 7 Cloud Deployment Models In a SaaS Model, the software is hosted at the cloud service provider s site 91% In a PaaS Model, the application framework is hosted at the cloud service provider s site 56% 53% In a IaaS Model, the compute, storage is available as a service

8 Security as a Service In a Security as a Service Model, the security functions are delivered as a service 53% Security as a Service 70% 57% 61% 43% 48% 35% Identity Management Threat Management Security Device Management Infrastructure Security Operations 8 Web Security Monitoring Vulnerability Assessment and Penetration Testing

14 14 Challenges faced by Cloud Providers Top 3 Challenges faced by Cloud providers 78% 59% 57% Technological limitation especially in Indian context where network bandwidth, latency and interoperability has been seen as a major challenge Meeting multiple regulatory compliance requirements, that vary considerably based on the type of data, geography and domain / industry. E.g. HIPAA for health records, GLBA for financial transactions, PCI DSS for credit card data, etc. Meeting multiple contractual requirements, especially when data protection requirements as well as data breach liabilities of different countries vary considerably Major challenges faced by cloud service providers Meeting multiple regulatory 59% Technological Limitations Meeting multiple contractual 57% Huge initial capital expenditure / 33% Inadequate Research and Development Alleviate negative perceptions about Unavailability of skilled resources Migration of services provided to client Technological Limitations (Indian 15% 19% 19% 24% 26% Enforcement of IT (Amendment) Act, 2008 will be a challenge as cloud computing Business benefits arising out of the use of cloud computing will influence the focus Under the Indian Telecom Licensing Policy, prohibition of data transfer outside the 78% Indian legal framework 38% 61% 63%

15 15 Role of NASSCOM DSCI in Cloud Computing Role of NASSCOM-DSCI in the Cloud computing ecosystem in India Promote data security and privacy in the evolving cloud based ecosystem Work closely with the government to create necessary policy environment for cloud computing 70% 68% Advise user organizations on the data security and privacy related aspects of cloud computing 48% Engage with the cloud providers to establish safe and secure cloud computing environment 55% Benchmark different cloud providers against their data security and privacy practices 45% This study is an important step for DSCI to chart out and drive the government policy initiatives for Cloud computing

16 16 Recommendations Security standards and certifications specific to Cloud environments need to be developed for successful implementation of Cloud services User organizations should involve Business, IT and legal team in framing of the contract provisions Cloud service providers - Transparency required with their processes, certifications, information security practices, and techniques Both User organizations and Cloud service providers should develop robust information security governance, regardless of the service or deployment model.
