Windows Azure security overview
Windows Azure, as an application hosting platform, must provide confidentiality, integrity, and availability of customer data.
This document describes the array of controls implemented within Windows Azure, so customers can determine if these capabilities and controls are suitable for their unique requirements. The overview begins with a technical examination of the security functionality available from both the customer's and Microsoft operations' perspectives - including identity and access management driven by Windows Live ID and extended through mutual SSL authentication; layered environment and component isolation; virtual machine state maintenance and configuration integrity; and triply redundant storage to minimize the impact of hardware failures. Additional coverage is provided to how monitoring, logging, and reporting within Windows Azure supports accountability within customers' cloud environments.
