Term 32
An Application Security Group (ASG) is a cloud networking feature that groups virtual machines logically and allows you to apply security rules based on the application workload, rather than individual IP addresses.
Term 33
Address Resolution Protocol (ARP) is a network protocol used to map a device's IP address to its physical MAC address so data can be delivered correctly on a local network.
Term 34
ARP poisoning is a network attack where an attacker sends fake Address Resolution Protocol messages to link their MAC address with a legitimate IP address, enabling them to intercept, modify, or stop data on a local network.
Term 35
An ARP reply is a network response sent by a device to answer an ARP request, providing its MAC address so the requesting device can map an IP address to a physical hardware address on a local network.
Term 36
An ARP request is a network broadcast message sent by a device to discover the hardware (MAC) address of another device on the same local network given its IP address.
Term 37
An ARP table is a data structure stored on a network device that maps IP addresses to their corresponding MAC addresses, enabling communication within a local network.
Term 38
Asymmetric encryption is a cryptographic method that uses a pair of keys—a public key for encryption and a private key for decryption—to securely exchange data without sharing a secret.
Term 39
The attack surface is the total sum of all points in a system, network, or application where an unauthorized user can try to enter or extract data.

Term 48
Azure Policy is a service in Microsoft Azure that lets you create, assign, and manage rules to ensure your resources stay compliant with your company standards and service-level agreements.
Term 49
A Backup Designated Router (BDR) is a router in an OSPF network that waits to take over as the Designated Router if the current one fails, reducing network downtime.
Term 50
A backup policy is a documented set of rules that defines what data to back up, how often, where to store it, and how long to keep it, ensuring data can be restored after loss.
Term 51
Banner grabbing is the process of connecting to a remote service to capture the banner it sends, which often reveals software type and version for reconnaissance.
Term 52
A bastion host is a specially hardened server on a network’s perimeter that allows authorized users to securely access internal systems from outside the network.
Term 53
BCP is a proactive process that creates a framework to ensure critical business functions continue during and after a disruptive event.
Term 54
