Which option is used to collect wireless traffic passively, for the purposes of eavesdropping or information gathering?
Click on the arrows to vote for the correct answerA. B. C. D.
The option used to collect wireless traffic passively for the purposes of eavesdropping or information gathering is wireless sniffers, also known as wireless network analyzers or wireless packet sniffers.
Wireless sniffers are software or hardware tools that can capture and analyze wireless network traffic transmitted over the airwaves. They can detect and record all types of wireless traffic, including unencrypted data, encrypted data, and control frames. This makes them useful for monitoring and analyzing network traffic, troubleshooting network issues, and conducting security assessments.
Wireless sniffers work by placing a wireless network interface into promiscuous mode, which allows it to capture all wireless traffic within range. The captured data is then analyzed by the sniffer software or hardware, which can provide detailed information about the wireless network, including the devices connected to it, the types of traffic being transmitted, and any security vulnerabilities that may exist.
Network taps, repeater Access Points, and intrusion prevention systems are not typically used for passive wireless traffic collection. Network taps are used to monitor traffic on a wired network by tapping into the physical cable, while repeater Access Points are used to extend the range of a wireless network. Intrusion prevention systems are used to detect and prevent security threats on a network, but they do not typically capture or analyze wireless traffic.
