ECS supports rotation of keys, a practice of changing keys to limit the amount of data that is protected by any given key to support industry standard practices. It can be performed on demand both through API and user interface and is designed to minimize the risk from compromised keys.
To initiate key rotation, select Settings > Key Management > Key Rotation > Rotate Keys, as shown in Figure 11.
Rotation is an asynchronous operation, and the latest status of the current operation can be seen in the table. The Rotate Keys table also lists the status of previous rotation operations.
