Which of the following is a packet sniffing tool listed among the material's examples?

• A. Dsniff
• B. Kismet
• C. Scapy
• D. Nmap

Answer: (A)

Packet sniffing involves capturing and inspecting packets traveling over a network to observe the traffic and extract information such as credentials or patterns. Dsniff is a well-known collection of tools designed for sniffing and intercepting network traffic, making it a direct example of a packet sniffing tool. It’s specifically associated with monitoring and capturing data from networks, which is the essence of sniffing. The other tools fit different roles: Kismet is focused on discovering and sniffing wireless (802.11) traffic and identifying access points and clients; Scapy is a flexible toolkit for crafting, sending, and dissecting packets rather than passively sniffing; Nmap is a network scanner used to map hosts, services, and vulnerabilities rather than capture traffic. Hence, Dsniff is the best choice.
