Final answer:
ARP Poisoning is the enumeration type that exploits application layer protocols to manage network devices, allowing attackers to intercept data by associating their MAC address with another IP on the network.
Step-by-step explanation:
The type of enumeration that takes advantage of vulnerabilities in the application layer protocol used to maintain and manage routers, hubs, and switches on an IP network is ARP Poisoning. ARP Poisoning is a technique used to intercept data on a local area network (LAN) by linking the attacker’s MAC address with the IP address of a legitimate computer or server on the network. This malicious activity enables the attacker to receive any data that is meant for that IP address. ARP Poisoning exploits the Address Resolution Protocol which operates at the application layer of the internet protocol suite to convert IP addresses into MAC addresses.
