Abstract:
It is desired to reduce the danger of leakage of data stored in a logical storage device. A storage system has a detection unit and a security processing unit. The detection unit detects a system change, during which it is not possible to perform I/O for a first logical storage device, among a plurality of logical storage devices in the storage system. And the security processing unit takes this type of system change as the opportunity for performing security processing, i.e. formatting or shredding, upon the first logical storage device.
