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.

Jim Hatfield

Senior Firmware Engineer; Seagate Technology; Work Group Co-Chair

Jim Hatfield is a senior firmware engineer for Seagate Technology and has been an active leader in storage and security standards development since 2002. He is a founding member of the TCG Storage WG (2004), and is the author and editor of the TCG Storage Interface Interactions Specification. He is an officer or participant in many storage and security standards organizations (INCITS T10 and T13, SATA-IO, NVMe, IEEE (1667, 1619, 1912), Common Criteria (EE). He was part of the team that created the first self-encrypting disc drive (SED). With 40 years of experience in the tape, HDD and SSD storage industries, Jim provides the glue between security solutions and real-world storage interactions. He holds a B.A. in Computer Science and Mathematics.

Dave Landsman

Director of Industry Standards; Western Digital; Work Group Co-Chair

Dave Landsman is Director of Industry Standards at Western Digital and has been active in storage standards development since 2008. He has done spec development at NVMe (Authenticated Boot, Write Protection), PCI-SIG (PCIe BGA, M.2), JEDEC (MO-276, MO-300, JESD 218/219, NVDIMM-P), SATA-IO (DevSleep, SATA BGA), INCITS T10/T13, and others. He was on the SATA-IO Board from 2012-2016, and is currently a Board member at NVMe (since 2012), and the Compact Flash Association (since 2016). Dave has been active in IEEE 1667 since 2008, and is currently the NVMe-TCG liaison with respect to NVMe-TCG collaboration on NVMe security requirements. He has presented TCG-NVMe joint work at the Flash Memory Summit. Dave holds a B.A. in Computer Science from the University of California, San Diego.
