Ethical Hacking Essentials Practice Test

Which tool would you use first to capture data packets while testing a wireless network’s security?

1. Aircrack-ng

2. Aireplay-ng

3. Airodump-ng

4. Airdecap-ng

The correct answer is: Airodump-ng

To capture data packets while testing the security of a wireless network, Airodump-ng is the appropriate choice. This tool is specifically designed for capturing raw 802.11 frames and displaying information about wireless networks in real-time. It can gather data on the packets transmitted over the air, allowing an ethical hacker to collect essential information about network activity, including client associations and the traffic being generated. Airodump-ng operates by putting the wireless network interface card into monitor mode, which allows it to listen to all the packets in the air, rather than only those directed to it. This functionality is crucial for wireless security testing, as it provides the foundational data needed for further analysis. Other tools, while part of the Aircrack-ng suite and valuable in their own right, serve different purposes. For example, Aircrack-ng is primarily used for cracking WEP and WPA/WPA2 encryption keys rather than for packet capture. Aireplay-ng is focused on packet injection to test the responsiveness of the access points, and Airdecap-ng is used to decrypt captured packets. These functionalities are pivotal in the overall process but are not the first step in the packet capture phase. Hence, Airodump-ng is the most suitable choice for capturing data packets initially
