Abstract
Despite a rocky start in terms of perceived security, cloud adoption continues to grow. Users are more comfortable with the notion that cloud can be secure but there is still a lack of understanding of what changes when moving to cloud, how to secure a cloud environment, and most importantly, how to demonstrate compliance of these cloud environment for regulatory purposes. This chapter reviews the basics of cloud security and compliance, including the split of security responsibility across Cloud provider and Client, considerations for the integration of cloud deployed workloads with on-premises systems and most importantly, how to demonstrate compliance with existing internal policies and workload required regulatory standards.
