BUILDING CUSTOMER TRUST IN CLOUD COMPUTING WITH TRANSPARENT SECURITY White Paper November 2009 Abstract Potential users of cloud services often fear that cloud providers’ governance is not yet mature enough to consistently and reliably protect their data. As the trend toward cloud-based services continues to grow, it has become clear that one of the key barriers to rapid adoption of enterprise cloud services is customer concern over data security (confidentiality, integrity, and availability). This paper introduces the concept of transparent security and makes the case that the intelligent disclosure of security design, practices, and procedures can help improve customer confidence while protecting critical security features and data, thereby improving overall governance. Readers will learn how transparent security can help prospective cloud computing customers make informed decisions based on clear facts. For the purpose of discussion and debate, a model leveraging the ISO 27000 series standards is presented as a commonly understood framework for disclosure. 2 Building Customer Trust in Cloud Computing with Transparent Security Sun Microsystems, Inc.Sun Microsystems, Inc.
