Acknowledgment (ACK) An acknowledgment of a signal being received.
Address Resolution Protocol (ARP) Used at the Media Access Control (MAC) layer to provide for direct
communication between two devices within the same LAN segment.
Advanced Persistent Threat (APT) An adversary with sophisticated levels of expertise and significant resources who
is able to use multiple different attack vectors (e.g., cyber, physical and
deception) to achieve its objectives. Its objectives are typically to establish and
extend footholds within the IT infrastructure of organizations in order to
continually exfiltrate information and/or to undermine or impede critical aspects
of a mission, program or organization, or place itself in a position to do so in the
future. Moreover, the APT pursues its objectives repeatedly over an extended
period of time, adapting to a defender's efforts to resist it, and with determination
to maintain the level of interaction needed to execute its objectives.
Application Programming Interface (API) Mobile code mechanisms that provide ways for applications to share data,
methods or functions over a network. Usually implemented either in XML or
JavaScript Object Notation (JSON). A reference to a software access point or
library function with a well- defined syntax and well-defined functionality.

Bandwidth The amount of information transmitted over a period of time. A process consisting
of learning or education could necessitate higher bandwidth than a quick status
update, which would require a lower bandwidth.
Bit Most essential representation of data (zero or one) at layer 1 of the OSI 7-Layer
Model.
Bluetooth (Wireless Personal Area Network IEEE 802.15) Bluetooth wireless technology is an open standard for short-range RF
communication used primarily to establish wireless personal area networks
(WPANs). It has been integrated into many types of business and consumer
devices.
Bound Network(s) Network in which devices are connected at layer 1 by means of physical cables,
wires or fiber. Often referred to as wired networks, Ethernet networks or by
wiring or cable standard used, (e.g., fiber network, Cat 5 or Cat 6 network). See
also Unbound (wireless) Network(s).
Boundary Routers Primarily advertise routes that external hosts can use to reach internal ones.
Bridges A device that creates a single aggregate network from separate network
segments. Using the OSI model, this device aggregates networks at layer 2.
