Best Free WiFi Network Security Tools for IT Managers

For corporate IT managers and network administrators, the best way to protect relatively vulnerable WiFi networks is to use the most popular and powerful tools in the hacker circle to invade your own wireless network, find network security loopholes and strengthen them in a targeted manner.

A few years ago, we recommended 15 free (almost free) WiFi network intrusion testing tools. In 2016, we updated this list based on the latest security intelligence and refined the 20 free tools recommended as follows:

  1. Aircrack
    Aircrack is the most popular WiFi password cracking tool. There are many tools on the market that can crack WiFi encryption, most of which use WEP security vulnerabilities or brute force dictionary attacks to crack WPA/WPA2 PSK passwords. WPA2 AES/CCMP encryption is still a relatively safe choice. If you use WPA2 PSK mode, your password should be at least 13 characters long with mixed characters. Before your Wi-Fi network is invaded or “freeloaded”, it is best to use a cracking tool to attack yourself first. Aircrack is an open source WEP/WPA/WPA2 PSK cracking tool that can run on Windows , Mac OS X, Linux and OpenBSD . It can be downloaded to a VMware image file or a Live CD file.

  1. Kismet
    Kismet is an open source WiFi scanner, packet sniffer and intrusion policy system that can run on Windows, Mac OSX, Linux and BSD. Kismet can display AP details, including hidden SSIDs, capture raw wireless data packets, and import data into tools such as Wireshark and TCPdump for analysis. In the Windows environment, due to driver limitations, Kismet can only work with CACE AirPcap wireless network cards. But on Mac OSX and Linux, Kismet is compatible with many wireless network cards.

  1. Wifiphisher
    The open source wireless security tool Wifiphisher can perform automated phishing attacks on WPA-encrypted AP wireless hotspots to obtain password accounts. Because it uses social engineering principles to implement man-in-the-middle attacks, Wifiphisher does not need to perform brute force cracking when carrying out attacks.

WiFiphiser is an open source software based on the MIT license model and runs on Kali Linux .
