ISO/IEC 14776 (all parts) provides for many different types of SCSI devices (e.g., disks, tapes, media changers). This part of ISO/IEC 14776 defines a device model that is applicable to all SCSI devices. Other command standards expand on the general SCSI device model in ways appropriate to specific types of SCSI devices.

ISO/IEC 14776 (all parts) specifies the interfaces, functions, and operations necessary to ensure interoperability between conforming SCSI implementations. This document is a functional description. Conforming implementations employ any design technique that does not violate interoperability.

This document defines security features for use by all SCSI devices. This document defines the security model that is basic to every device model and the parameter data that applies to any device model. For additional information on the security goals and threat model discussed in this document see Annex A.
