A company recruited a penetration tester to configure intrusion detection over the wireless network. Which of the following tools would BEST resolve this issue?

Aircrack-ng is a suite of tools primarily used for cracking WEP/WPA keys and attacking wireless networks, not for passive intrusion detection.

Wireshark is a general-purpose packet analyzer used for capturing and inspecting network traffic, but it lacks the automated intrusion detection and real-time alerting capabilities specific to wireless threats that Kismet provides.

Cowpatty is a tool specifically used for offline brute-forcing of WPA-PSK hashes, which is an offensive password cracking technique, not a solution for wireless intrusion detection.

Kismet is a dedicated wireless network detector, sniffer, and intrusion detection system that can identify networks, clients, and detect various wireless attacks or anomalies in real-time, making it the most suitable tool for wireless intrusion detection.
