API
  • Also known as: Application Programming Interface

 A set of tools and procedures provided by the programmer of an application so that other programmers can control, exchange data with, or extend the functionality of an application.

Protocol for mapping IP addresses to physical addresses such as Ethernet or Token Ring.

ARP spoofing
  • Also known as: ARP trashing, spoofing

Type of attack in which a malicious actor sends falsified ARP (Address Resolution Protocol) messages over a local area network. This results in the linking of an attacker's MAC address with the IP address of a legitimate computer or server on the network.

ASCII

Referring to a standard 7-bit character system that includes the alphanumeric characters and printer control codes.

authoritative DNS

Name server that gives answers in response to queries about names in a DNS zone.

authority zone

Associated with DNS. A section of the domain-name tree for which one name server is the authority.

Auto Scaling Group

A representation of multiple EC2 instances that share similar characteristics, and that are treated as a logical grouping for the purposes of instance scaling and management.

A managed cloud platform that lets connected devices easily and securely interact with cloud applications and other devices.

AWS region

A named set of AWS resources in the same geographical area. A region comprises at least two Availability Zones.

AWS Management Console

A simple and intuitive web-based user interface to access and manage AWS.

back-end server

Part of the back-end process, that usually consists of server, application, and database. The back end is where the technical processes happen, as opposed to the front end, which is usually where the user's interaction occurs.

backbone

Referring to the Internet, a central network that provides a pathway for other networks to communicate.

Balance-XOR

Operating mode for Ethernet bundles where the link is chosen by calculating the hash out of the source/destination MAC (Layer 2) combined with the IP addresses (Level 3).

bandwidth

Rate of data transfer, usually expressed in multiples of bits per second (bps).

Barracuda Campus
