SECURE VIRTUAL SECTOR ERASURE METHOD AND SYSTEM

摘要

Systems and methods for sanitizing physical storage in cloud computing and virtual environments. When logical storage is decommissioned in a virtual environment, the underlying physical storage is logically disassociated. However, the underlying physical data blocks remain intact until they are overwritten. Since there is no control over when, or even if, the physical data is ever overwritten, the remaining data is susceptible to compromise. The present disclosure provides a secure erase application that securely erases physical storage associated with to-be deleted resources, such as virtual data stores, virtual images, snapshots and raw virtual disks.

1. A method comprising:
presenting a virtual resource in a user interface; receiving a selection of the virtual resource, the selection indicating that the virtual resource is to be securely erased; isolating the selected virtual resource; obtaining access to the selected virtual resource; and securely erasing the selected virtual resource by overwriting all virtual sectors of the selected virtual resource.
