Did you know that we conduct regular penetration testing to improve Windows Azure security controls and processes? In addition, we understand that security assessment is also an important part of our customers' application development and deployment, so 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.
