Abstract
Secure deletion of a storage device includes monitoring the storage device, determining whether a predetermined condition occurs, and accessing the storage device when it is determined that the predetermined condition occurs. Further, deleted information to be securely wiped is identified in accordance with a predetermined unified policy for a virtual environment comprising the storage device. Alternatively, information being deleted is intercepted when it is determined that the information being deleted satisfies a predetermined condition. The identified or intercepted deleted information is securely wiped from the storage device by filling a portion of the storage device associated with the deleted information with zero bytes before the deleted information is marked as deleted. The secured wiping of deleted information may occur in accordance with a predetermined enterprise-wide policy.
