The Storage Work Group builds upon existing TCG technologies and philosophy, and focuses on standards for security services on dedicated storage systems. One objective is to develop standards and practices for defining the same security services across dedicated storage controller interfaces, including but not limited to ATA, Serial ATA, SCSI, FibreChannel, USB Storage, IEEE 1394, Network Attached Storage (TCP/IP), NVM Express, and iSCSI. Storage systems include disk drives, removable media drives, flash storage, and multiple storage device systems.
