Windows Azure runs in geographically dispersed datacenters that comply with key industry standards, such as ISO/IEC 27001:2005, for security and reliability. They are managed, monitored, and administered by Microsoft operations staff that have years of experience in delivering the world’s largest online services with 24 x 7 continuity.
In addition to datacenter, network, and personnel security practices, Windows Azure incorporates security practices at the application and platform layers to enhance security for application developers and service administrators.
Standard Response to Request for Information: Security and Privacy
The Cloud Security Alliance published the Cloud Control Matrix (CCM) to support customers in the evaluation of cloud services. In response to this publication, Microsoft has created a white paper to outline how Windows Azure security controls map to the CCM controls framework, providing customers with in-depth information on Windows Azure security policies and procedures. Please see Windows Azure Cloud Security Alliance STAR submission for more information.
Windows Azure Security Incident and Abuse Reporting
To report suspected security issues or abuse of Windows Azure, please contact the cert.microsoft.com team, which is available 24x7.
Microsoft conducts regular penetration testing to improve Windows Azure security controls and processes. We understand that security assessment is also an important part of our customers' application development and deployment. Therefore, we have established a policy for customers to carry out authorized penetration testing on their applications hosted in Windows Azure. Because such testing can be indistinguishable from a real attack, it is critical that customers conduct penetration testing only after obtaining approval in advance from Windows Azure Customer Support. Penetration testing must be conducted in accordance with our terms and conditions. Requests for penetration testing should be submitted with a minimum of 7-day advanced notice.
To learn more or to initiate penetration testing, please download the Penetration Testing Approval Form and then contact Windows Azure Customer Support.
