3 Executive Summary The goal of the study was to better understand what business decisionmakers in small and medium-sized organizations think about privacy as they adopt cloud computing. Specifically, we wanted to determine their concerns about cloud computing related to privacy and how cloud providers can ameliorate them. More than half (56 percent) of respondents say their organizations are moderate or heavy users of cloud computing resources and they expect their use of cloud resources to increase over the next two years, even though they are concerned about how they will manage data privacy in the cloud. The research also found that the privacy reputation and practices of cloud computing providers figure prominently into cloud computing purchasing decisions. Seventy-six percent of respondents stated that privacy influenced their choice of providers. Cloud provider privacy practices cited as particularly important are: Disclosure of physical location of data (61 percent of respondents) Strict processes to separate customer data (58 percent) Agreement not to mine customer data for advertising (50 percent) Provides European Union model clauses as contractual agreements (43 percent) With organizations increasingly moving to the cloud, it is becoming more important to ensure that privacy commitments and obligations are met. Fifty-six percent of respondents say they are confident that their organization is capable of achieving privacy when deploying cloud applications or services. The Ponemon Institute surveyed 1,771 individuals in positions within IT, compliance, data security, risk management, and privacy in the United States, Germany, and the Nordic countries (Denmark, Finland, Norway, and Sweden), and created three separate reports. This report focuses on Germany, where Ponemon surveyed 668 individuals who had, on average, approximately 10 years of business experience. More than half (52 percent) report to the Chief Information Officer, followed by 17 percent who report to the Compliance Officer and 16 percent who report to the Chief Information Security Officer. Topics addressed in this study > Perceptions about privacy, data protection, and the use of cloud resources > The state of cloud computing in small and medium-sized organizations > Country differences in attitudes about cloud computing and privacy In the following sections, we present an analysis of the most salient findings of this research, as well as recommendations to help organizations improve privacy in the cloud. The complete findings of this research are presented in the appendix to this report. 2

4 Perceptions about privacy, data protection, and the use of cloud resources Cloud computing is considered an important part of IT operations Fifty-six percent of organizations in this study make either heavy or moderate use of cloud computing. Only 17 percent say their use is light. The majority (52 percent) use public cloud services, though there is also some use of private cloud services (39 percent). Reliance on cloud computing is also expected to increase, as 84 percent of respondents expect cloud computing to be either important, very important, or essential to their organizations in two years, up from 66 percent who view cloud computing that way today. Organizational commitment to privacy and data protection in the cloud Seventy-three percent of respondents say their organizations are committed to protecting confidential or sensitive information. Thus, the majority of respondents say their organizations are taking the following positive actions, as shown in Figure 1. figure 1 ACTIONS THAT ARE PRACTICED TO PROTECT DATA AND PRIVACY IN THE CLOUD Extremely careful about sharing confidential or sensitive personal information with third parties, including cloud providers respect the privacy rights of customers, employees, consumers, and other stakeholders proactive compliance management with privacy and data protection laws, regulations, and other requirements establish clearly defined accountability for safeguarding confidential or sensitive personal information assess the impact that the use of cloud computing has on their privacy commitments and obligations determine what personal data is too sensitive for the cloud environment vigilant in assessing the inherent risks when using or storing personal data in the cloud environment 65% 62% 58% 58% 55% 73% 69% 3

5 Perceptions about privacy, data protection, and the use of cloud resources Based on steps taken to advance privacy practices in their organizations, 56 percent of respondents are confident that their organizations are capable of meeting their privacy commitments when deploying cloud applications or services. Impact of sufficiency of privacy practices on selection of cloud providers As shown in Figure 2, 76 percent of respondents say their organizations do consider the level of commitment a cloud provider has for achieving privacy in the cloud when they are making purchasing decisions, including 45 percent who say privacy policies had a significant or very significant impact. figure 2 Impact of cloud provider s privacy policies and practices on SELECTION OF CLOUD PROVIDERS some to significant impact 58% 18% very significant impact 21% 3% unsure no impact Figure 3 shows the privacy features and policies of cloud providers regarded as very important or important when evaluating a cloud provider s commitment to privacy. Specifically, 61 percent of respondents believe disclosure of physical location of data is critical, 58 percent want strict processes to separate customer data from other customers, 50 percent of respondents want cloud providers not to mine customer data for advertising purposes, and 43 percent say providing European Union s model clauses as contractual agreements is important. figure 3 Important issues that determine the cloud providers commitment to privacy VERY IMPORTANT AND IMPORTANT RESPONSES COMBINED the cloud provider discloses the physical location of data storage the cloud provider has processes in place to ensure that customer data is separate from that of other customers the cloud provider agrees not to mine customer data the cloud provider provides european Union s model clauses as contractual agreements 61% 58% 50% 43% 4

6 The state of cloud computing in organizations Cloud computing is now an integral part of IT Figure 4 reveals that 66 percent of respondents say that cloud computing applications or services are essential or important to meeting their organization s IT and data processing objectives today. This percentage is expected to increase to 84 percent 24 months from now. figure 4 Importance of cloud computing in meeting Information technology and data processing objectives today 5% 7% 24 months from now 34% 23% 38% 43% 30% 13% 4% 3% essential very important important not important irrelevant As shown in Figure 5, the top three cloud computing applications used in German small-to-medium businesses (SMBs) today are infrastructure applications such as online backup, security, and archiving; business applications like CRM and webmail; and peer-to-peer applications such as instant messaging. figure 5 Cloud computing applications currently in use more than one choice permitted infrastructure applications business applications peer-to-peer social media applications 74% 56% 46% 38% we don t use cloud solution stacks services storage other applications or services 28% 17% 9% 36% 3% 5

7 The state of cloud computing in organizations The anticipated growth in cloud computing is shown in Figure 6. Based on an extrapolated average, cloud computing resources meet 23 percent of organizations total IT and data processing requirements, and this is expected to increase to 37 percent over the next 24 months. figure 6 percentage of information technology requirements met by cloud computing today 24 months from now 32% 21% 23% 9% 14% 19% 11% 6% 7% 9% 12% 5% 6% 11% 0% 7% 2% 1% 1% 5% none <10% 11% 20% 21% 30% 31% 40% 41% 50% 51% 60% 61% 70% 71% 80% >80% Although use of cloud computing is increasing rapidly, it does not seem to affect organizational privacy commitments figure 7 IMPACT OF CLOUD COMPUTING ON ORGANIZATIONAL responsibility to safeguard information Only 35 percent of respondents say the use of cloud resources increases their organization s responsibility to safeguard customer, employee, consumer, and other stakeholders personal information. Figure 7 also shows that 47 percent of respondents say it does not impact their organization s responsibility. It seems, therefore, that organizations are relying on the cloud provider to ensure the security of their sensitive data when deployed to the cloud. cloud computing does not affect our responsibility 47% 18% 35% cloud resources decrease our responsibility cloud resources increase our responsibility 6

8 The state of cloud computing in organizations Organizations rely on cloud provider contracts, third-party audit reports, and self-assessments in the vetting process Fifty-one percent of respondents say their organizations evaluate cloud applications for privacy and data protection considerations before engagement or deployment by their end users. As shown in Figure 8, the top three steps organizations take to vet cloud providers are contractual negotiation and legal review (64 percent), proof of compliance such as an audit report (52 percent), and self-assessment checklist or questionnaire completed by the provider (39 percent). As shown in Figure 10, to secure sensitive and confidential data, the majority of respondents say they rely on assurances from the cloud provider (70 percent) or reliance on contractual agreements with the cloud provider (59 percent). Only 40 percent say they use conventional data security tools such as encryption to protect information in the cloud. figure 8 Methods for vetting or evaluating cloud providers more than one choice permitted 64% 52% 39% contractual negotiation and legal review proof of compliance Further, 38 percent say they look at adherence to a certification standard and they consider SAS-70 (which is currently being replaced by the SSAE 16 standard) and PCI DSS as the certifications most important for evaluating cloud providers (51 percent and 48 percent, respectively). Forty-three percent say the ISO certification is most important (Figure 9). figure 9 Most important certifications used when evaluating cloud providers two choices permitted sas-70 pci dss iso other 2% 51% 48% 43% figure 10 Methods for securing confidential or sensitive personal information in the cloud more than one choice permitted we rely on assurances from the cloud provider 70% self-assessment checklist completed by provider we rely on contractual agreements with the cloud provider 59% we use conventional data security tools to protect information 40% we buy additional security services provided by the cloud provider 10% don t know 9% other 2% 7

9 The state of cloud computing in organizations Certain assurances from the cloud vendor influence organizational decisions to purchase services As discussed previously, 76 percent of respondents say that the privacy policies and practices of their cloud providers would impact their cloud purchasing decisions, so there are certain assurances that could make a difference. Figure 11 shows that 79 percent of respondents would be much less likely or less likely to purchase cloud services if the cloud vendor reported a material data breach involving the loss or theft of sensitive or confidential personal information. figure 11 The impact of a material data breach on the decision to use a cloud provider much less likely to buy cloud services 45% 34% less likely to buy cloud services 4% 17% unsure no effect on the decision to buy cloud services 8

10 The state of cloud computing in organizations Sixty percent of respondents say assurances from a bona fide and credible third party that the cloud vendor meets all privacy and data protection requirements, including regulations and laws in various countries, would make them much more or more likely to purchase cloud services (Figure 12). Forty-two percent say their decision to buy would improve if a third party provided assurance that the cloud provider meets privacy and protection requirements. figure 12 Conditions that affect the decision to use a cloud provider Third party provides assurance that the cloud provider meets privacy and protection requirements THE CLOUD PROVIDER AGREES to meet all privacy and data protection requirements 17%15% 43% 27% 35% 55% 5% 3% much more likely to buy cloud services more likely to buy cloud services no effect on the decision to buy cloud services unsure The following findings discuss what practices would help organizations achieve privacy in the cloud and what organizations are doing. Understand the types of confidential information that are too risky to be used or stored in the cloud As shown in Figure 13, the types of data that German SMBs are most concerned about putting in the cloud are health records (67 percent); intellectual property such as source code, design plans, and architectural renderings (63 percent); and employee records (56 percent). figure 13 Information too risky to be used in the cloud more than one choice permitted 67% 51% 29% 2% health records research data customer account information other 63% 39% 24% 29% intellectual property customer payments non-financial business information none of the above 56% 37% 9% employee records financial business information consumer data 9

11 Country differences in cloud privacy In this study, Ponemon Institute surveyed 1,771 individuals in IT, compliance, data security, risk management and privacy in the United States, Germany and the Nordic countries (Denmark, Finland, Norway, and Sweden). In this section, we present some of the most salient differences that emerged in this research. Confidence about data privacy in the cloud. figure 14 Confidence that privacy obligations are met when deploying cloud applications VERY CONFIDENT AND CONFIDENT RESPONSES COMBINED u.s. germany nordic countries 39% 56% 46% How does confidence in meeting privacy commitments when deploying cloud applications or services differ among countries in this study? As Figure 14 shows, German respondents are far more confident that their organizations can fulfill their privacy obligations when deploying cloud services than respondents in the United States. 10

12 The state of cloud computing in organizations The impact of cloud service privacy practices on purchase decisions Impressions about a cloud service provider s commitment to privacy has the most impact among respondents in Germany and the Nordic countries, according to Figure 15. figure 15 Impact of cloud provider s privacy policies and practices on SELECTION OF CLOUD PROVIDER u.s. germany nordics very significant impact unsure 12% 18% 21% significant impact some impact no impact 3% 3% 5% 18% 27% 28% 29% 31% 31% 38% 21% 14% As shown in Figure 16, SMBs in the U.S. and Germany want cloud providers to disclose the physical location of data storage, including the location of replicated or backed-up data files. In the Nordic countries, it is most important that the cloud provider has strict processes and procedures in place to ensure that customer data is separate from other customers. figure 16 Important issues that determine the cloud provider s commitment to privacy Very important and important responses combined u.s. germany nordic countries the cloud provider discloses the physical location of data storage 62% 61% 53% the cloud provider has processes in place to ensure that customer data is separate from that of other customers 54% 58% the cloud provider agrees not to mine customer data 44% 50% the cloud provider uses european union s model clauses as contractual agreements 24% 43% 56% 49% 35% 11

13 Conclusion Achieving privacy in the cloud is a challenge for all organizations. We recommend that organizations assess the specific, proactive steps they can take to protect sensitive information in the cloud, such as: Create policies and procedures that clearly state the importance of protecting sensitive information stored in the cloud. The policy should outline what kinds of information are considered sensitive and proprietary. Evaluate the security posture of third parties before sharing confidential or sensitive information. As part of the process, corporate IT or IT security experts should conduct a thorough review and audit of the vendor s security qualifications. Train employees to mitigate the security risks specific to cloud technology to make sure that sensitive and confidential information is not threatened. Establish an organizational structure that allows the CIO, CISO, or other security and privacy leaders to participate actively in the vetting, purchasing, and implementing processes to ensure that they are handled appropriately. If appropriate, establish a functional role dedicated to informationgovernance oversight to better protect the business. Define a policy that governs the protection of sensitive and confidential data and applications that organizations put in the cloud. Ponemon Institute also recommends that cloud computing providers offer greater transparency into their security infrastructure to help ensure customer confidence that information stored in the cloud is secure. 12

14 Method Table 1 reports the sample frame of 21,005 individuals in Germany who have bona fide credentials in the IT, compliance, data security, risk management, and privacy fields. In total, 699 respondents completed the survey. Of the returned instruments, 31 surveys failed reliability checks. A total of 668 surveys were used as the final sample, which represents a 3.2 percent response rate. table 1 GERMAN SAMPLE RESPONSE RESPONDENTS PERCENTAGE SAMPLING FRAME 21, % INVITATIONS SENT 20, % TOTAL RETURNS % TOTAL REJECTS % FINAL SAMPLE % Pie Chart 1 summarizes the approximate position levels of respondents in our study.

15 Survey Limitations There are inherent limitations to survey research that must be carefully considered before drawing inferences from findings. The following items are specific limitations that are germane to most web-based surveys. Non-response bias. The findings are based on a sample of survey returns. The researchers sent surveys to a representative sample of individuals, resulting in the return of a large number of usable responses. Despite non-response tests, it is always possible that individuals who did not participate are substantially different from those who completed the survey in terms of underlying beliefs. Sampling-frame bias. Research accuracy is based on contact information and the degree to which the list is representative of individuals who are knowledgeable about protecting data in the cloud environment. The researchers recognize that the results may be biased by external events such as media coverage. They also acknowledge that there may be bias because subjects were compensated for completing the surveys. Self-reported results. The quality of survey research is based on the integrity of confidential responses received from subjects. While certain checks and balances can be incorporated into the survey process, there is always the possibility that a subject did not respond truthfully. 14
