Aircrack-ng
Aircrack-ng is one of the best wireless password hack tools for WEP/WAP/WPA2 cracking utilized worldwide!
It works by taking packets of the network, analyses it via passwords recovered. It also possesses a console interface. In addition to this, Aircrack-ng also makes use of standard FMS (Fluhrer, Mantin, and Shamir) attack along with a few optimizations such as the KoreK attacks and PTW attack to quicken the attack which is faster than the WEP.

It does not actively block any vulnerabilities that your computers have but it will be able to sniff them out by quickly running 1200+ vulnerability checks and throwing alerts when any security patches need to be made.
WireShark
WireShark is an open-source packet analyzer that you can use free of charge. With it you can see the activities on a network from a microscopic level coupled with pcap file access, customizable reports, advanced triggers, alerts, etc.
It is reportedly the world’s most widely-used network protocol analyzer for Linux.
Snort
Snort is a free and open-source NIDS with which you can detect security vulnerabilities in your computer.
With it you can run traffic analysis, content searching/matching, packet logging on IP networks, and detect a variety of network attacks, among other features, all in real-time.
Kismet Wireless
Kismet Wireless is a intrusion detection system, network detector, and password sniffer. It works predominantly with Wi-Fi (IEEE 802.11) networks and can have its functionality extended using plugins.
Nikto
Nikto2 is a free and open-source web scanner for performing quick comprehensive tests against items on the web. It does this by looking out for over 6500 potentially dangerous files, outdated program versions, vulnerable server configurations, and server-specif problems.
Yersinia
Yersinia, named after the yersinia bacteria, is a network utility too designed to exploit vulnerable network protocols by pretending to be a secure network system analyzing and testing framework.
It features attacks for IEEE 802.1Q, Hot Standby Router Protocol (HSRP), Cisco Discovery Protocol (CDP), etc.
Burp Suite Scanner
Burp Suite Scanner is a professional integrated GUI platform for testing the security vulnerabilities of web applications.
It bundles all of its testing and penetration tools into a Community (free) edition, and professional ($349 /user /year) edition

BeEF (The Browser Exploitation Framework)
BeEF, as the name implies, is a penetration tool that focuses on browser vulnerabilities. With it you can asses the security strength of a target environment using client-side attack vectors.
Maltego
Maltego is propriety software but is widely used for open-source forensics and intelligence. It is a GUI link analysis utility tool that provides real-time data mining along with illustrated information sets using node-based graphs and multiple order connections.
Fern Wifi Cracker
Fern Wifi Cracker is a Python-based GUI wireless security tool for auditing network vulnerabilities. With it, you can crack and recover WEP/WPA/WPS keys as well as several network-based attacks on Ethernet-based networks.
GNU MAC Changer
GNU MAC Changer is a network utility that facilitates an easier and quicker manipulation of network interfaces’ MAC addresses
Wifite2
Wifite2 is a free and open-source Python-based wireless network auditing utility tool designed to work perfectly with pen-testing distros. It is a complete rewrite of Wifite and thus, features an improved performance.
It does a good job at decloaking and cracking hidden access points, cracking weak WEP passwords using a list of cracking techniques, etc.
Pixiewps
Pixiewps is a C-based brute-force offline utility tool for exploiting software implementations with little to no entropy. It was developed by Dominique Bongard in 2004 to use the “pixie-dust attack” with the intention to educate students.
Depending on the strength of the passwords you’re trying to crack, Pixiewps can get the job done in a mater of seconds or minutes.
