Enterprise security is the key to achieving global information security in business and organizations. Cloud computing is a new paradigm for enterprise where businesses need to be secured. However, this new trend needs to be more systematic with respect to cloud security, which is a factor in sustaining cloud technology by building-in trust. For example, current challenges with cyber security and application security flaws are highlighting important lessons to be learned and also lead to the adoption of best practices. Similarly, as the demand for cloud services increases, the importance of security and privacy will also increase. One solution is to develop a framework for enterprise security to analyze and model organizational security of the cloud and its data. In particular, cloud data and cloud storage technologies (Amazon s3, drop box, Google drive, etc.) have now become normal practice for almost every computing user. This can explain why building trust for cloud users is one of the main focuses of cloud computing research. On the other hand, the social, human and business aspects of enterprise security are essential to users to keep their skills, business concepts and policies up-to-date. By maintaining all these aspects of security, organizations can develop an enterprise security solution to work together with business models, such as cloud provider enterprise model and cloud consumer enterprise model. In this way, enterprise security can address technical and organizational aspects of security to provide added value and win-win situations for users, adopters and service providers. Following the successful delivery of our workshop in 2014, we oversee the importance of enterprise security as a unique and rising field to ensure all aspects of security and risks can be identified, surveyed, tested, prototyped and minimized with recommendations and lessons learned disseminated. By blending technical and organizational aspects of security, our workshop can provide a platform for intellectual discussions and interactions. To highlight the significance of enterprise security and disseminate research contributions in cloud community, we welcome papers addressing technical (implementations, algorithms, experiments, simulation, modeling and prototypes) and organizational (information system related issues, recommendation and best practices, frameworks, risks) issues. We offer the best paper awards and winners will be invited to contribute to high-quality journals.
