What is the purpose of using tools like Kismet in network security?

• A. To detect and analyze wireless network traffic.
• B. To perform port scanning on wired networks.
• C. To encrypt wireless communications.
• D. To monitor user activity on endpoints.

Answer: (A)

Kismet is used to detect and analyze wireless network traffic. It functions as a wireless detector, sniffer, and intrusion detection system for 802.11 networks, passively capturing and decoding wireless frames to reveal nearby access points, clients, channels, signal strengths, and security configurations. This enables wireless site surveys, rogue-AP detection, and traffic analysis for security assessments, often logging data for offline review in tools like Wireshark. It’s focused on wireless traffic analysis, not on port scanning for wired networks, encrypting wireless communications, or monitoring user activity on endpoints.
