Abstract
The present disclosure provides a methodology by which disk level access for storage drives of a storage array may be highly secured based on permission settings applied to the driver interface of the storage drives. Based on specific set of access rules, a security component applies security profiles to permit/deny access to an individual storage drive, sets the storage drive with a first security level, monitors for a triggering event, and sets the storage drive to a second (more restrictive) security access level in response to the triggering event. In addition, the security component generates an alert in response to the triggering event. Thus, disk level access permissions are applied at a driver interface layer and permissions are applied based on administrator-defined policies. The present disclosure provides for complete lock-down of data permissions, management and/or restriction of IO loads, and protection of 'read-only' data integrity from overwrites.
