Physical security pertains to the management of data center buildings and facilities, physical servers, and networking devices. Physical security includes protection from unauthorized access to the facility. It also involves ensuring uninterrupted service by securing a reliable power supply, air and cooling regulation, and physical device management.
The public cloud providers accept full responsibility for ensuring the physical security of their data centers.
This provides one of the main advantages of moving the infrastructure to the public cloud.
Since physical security is handled by the platform, we will not discuss it further in this chapter. The details of physical security implementation in Azure are not disclosed publicly, however, some information can be acquired from Azure compliance reports. The reports can be found on the Azure Trust Center website https://azure.microsoft.com/en-us/support/trust-center.
