Companies have improved their practices around cloud computing security, yet concerns still exist about who is most responsible for cloud security.

The Security of Cloud Computing Users 2013 study by the Ponemon Institute and CA Technologies reveals that organizations today are more confident in the security of cloud computing and have put in place better security practices around cloud use. Still, affirmative responses were only around half (50 percent) for questions involving cloud security best practices, confidence in cloud services and knowledge of the cloud services in use within an organization.

The study also revealed that:

• Cloud confidence and best practices are improving but further progress can be made. Positive survey responses only hovered around half (50 percent) for any given question around cloud security best practices, such as vetting services for security risk, engaging the security team in determining cloud service use and assessing how a cloud service could impact data security. In addition, while this statistic improved by five percent from the 2010 survey, only 50 percent of organizations are confident they know all the cloud services in use within their organization.

• Responsibility for cloud security is mixed with a bias toward end users and IT Security getting a pass. The survey shows a concerning lack of agreement remains regarding who has responsibility for cloud security. While some organizations expect their cloud services providers to ensure the security of SaaS and IaaS applications (36 percent and 22 percent, respectively), a significant amount of the responsibility is assigned to companies’ end-users (31 percent for SaaS; 21 percent for IaaS), and very little responsibility was assigned to IT Security (eight percent for SaaS and 10 percent for IaaS). This relinquishment of responsibility points to a lack of clarity around ownership, which may lead to gaps in security processes and governance.

• Users prefer hybrid identity and access management (IAM) security solutions. Sixty-four percent of survey respondents would prefer a hybrid IAM implementation that supports both on-premise and cloud-based applications.

“Confidence in and best practices for the security of cloud computing is improving but not as significantly as one might have expected since our 2010 study,” said Dr. Larry Ponemon, chairman and founder, Ponemon Institute. “Our latest study offers organizations new data that should spark them to examine their own internal practices which could result in improvements in how they adopt and secure cloud services and applications.”
