Martin, a network security auditor, is aware that his company uses a switched network, which cannot be sniffed by some programs without some tweaking. What technique could he use to sniff his agency’s switched network?
A. ARP spoof the default gateway
B. Conduct MiTM against the switch
C. Launch smurf attack against the switch
D. Flood the switch with ICMP packets
The correct answer is A.
In computer networking, ARP spoofing, ARP cache poisoning or ARP poison routing, is a technique by which an attacker sends (spoofed) Address Resolution Protocol (ARP) messages onto a local area network. If Martin can successfully spoofs the default gateway, all the traffic in the network will be routed through his system and the network adapter can listen to all the traffic passing in the network.
