SBP2
The Serial Bus Protocol 2 (SBP-2) standard is a transport protocol within the Serial Bus, IEEE Std 1394-1995 (also known as FireWire or i.Link), developed by T10. Original work on Serial Bus Protocol started as an attempt to adapt SCSI to IEEE Std 1394-1995 serial interface. Later on it was recognized that SBP-2 may have a more general use, and the work on the standard was targeted to provide a generic framework for delivery of commands, data, and status between Serial Bus peripherals.

DMA Attack
A DMA attack is a type of side channel attack in computer security, in which an attacker can penetrate a computer or other device, by exploiting the presence of high-speed expansion ports that permit direct memory access (DMA). DMA is included in a number of connections, because it allows a connected device (such as a camcorder, network card, storage device or other useful accessory or internal PC card) to transfer data between itself and the computer at the maximum speed possible, by using direct hardware access to read or write directly to main memory without any operating system supervision or interaction. The legitimate uses of such devices have led to wide adoption of DMA accessories and connections, but an attacker can equally use the same facility to create an accessory that will connect using the same port, and can then potentially gain direct access to part or all of the physical memory address space of the computer, bypassing all OS security mechanisms and any lock sc ...

IEEE 1394
IEEE 1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple in cooperation with a number of companies, primarily Sony and Panasonic. It is most commonly known by the name FireWire (Apple), though other brand names exist such as i.LINK (Sony), and Lynx (Texas Instruments). The copper cable used in its most common implementation can be up to long. Power and data is carried over this cable, allowing devices with moderate power requirements to operate without a separate power supply. FireWire is also available in Cat 5 and optical fiber versions. The 1394 interface is comparable to USB. USB was developed subsequently and gained much greater market share. USB requires a host controller whereas IEEE 1394 is cooperatively managed by the connected devices. History and development FireWire is Apple's name for the IEEE 1394 High Speed Serial Bus.

SCSI
Small Computer System Interface (SCSI, ) is a set of standards for physically connecting and transferring data between computers and peripheral devices, best known for its use with storage devices such as hard disk drives. SCSI was introduced in the 1980s and has seen widespread use on servers and high-end workstations, with new SCSI standards being published as recently as SAS-4 in 2017. The SCSI standards define commands, protocols, electrical, optical and logical interfaces. The SCSI standard defines command sets for specific peripheral device types; the presence of "unknown" as one of these types means that in theory it can be used as an interface to almost any device, but the standard is highly pragmatic and addressed toward commercial requirements. The initial Parallel SCSI was most commonly used for hard disk drives and tape drives, but it can connect a wide range of other devices, including scanners and optical disc drives, although not all controllers can handle ...
