While conducting an assessment on a small firm's network, you see several broadcast names associated with different wireless devices. You want to learn details such as the manufacturer, channels in use, and encryption settings. Which method is most effective for this purpose?
Monitoring DNS activity to list available domains
Capturing handshake data and attempting decryption
Gathering and analyzing DHCP broadcast messages
Passively capturing beacon frames with a specialized scanner
Using a specialized scanner that passively tracks beacon frames is effective because the frames reveal the access point's name, hardware details, encryption type, and channel information using passive methods. Tools that collect handshake data or track DHCP details focus on different information and do not provide as much insight into channel and manufacturer details. Monitoring DNS requests shows limited access to encryption settings and channel usage.
