Address Resolution Protocol (ARP) spoofing, also known as ARP poisoning or ARP Poison Routing (APR), is a technique used to attack an Ethernet wired or wireless network. ARP spoofing may allow an attacker to sniff data frames on a local area network (LAN), modify the traffic, or stop the traffic altogether. The principle of ARP spoofing is to send fake ARP messages to an Ethernet LAN. What steps can be used as a countermeasure of ARP spoofing? Each correct answer represents a complete solution. Choose all that apply.

Question

Accepted Answer

B. Using ARP Guard utility ARP Guard is a legitimate network security utility designed to detect and block ARP spoofing attacks by monitoring ARP traffic and validating ARP replies against a trusted mapping database. C. Using static ARP entries on servers, workstation and routers Static ARP entries manually bind IP addresses to MAC addresses on servers, workstations, and routers, preventing an attacker's fake ARP replies from overwriting the ARP cache and redirecting traffic. D. Using ARP watch utility ARPwatch is a Unix-based utility that continuously monitors Ethernet/IP address pairings and sends alerts when unexpected changes occur, enabling early detection of ARP poisoning attempts. E. Using IDS Sensors to check continually for large amount of ARP traffic on local subnets IDS sensors can be configured to flag abnormal volumes of ARP broadcast traffic on local subnets, which is a common indicator that an attacker is flooding the network with spoofed ARP replies.
