Cybersecurity professionals are always on the lookout for effective and free tools to help secure their systems, and luckily for them, there are a wide range of options available. From wireless security and web app testing to phishing assessment and vulnerability scanning, the free cybersecurity tools listed below are essential for any organization looking to bolster their security measures.
One such tool is Aircrack-ng, a suite of wireless security tools that focuses on different aspects of Wi-Fi security. It includes programs for capturing, analyzing and exporting packet data, spoofing access points or routers, and decrypting WEP or WPA-encrypted files. Aircrack-ng is widely used and is completely free and open source.
Another vital tool is Burp Suite, which is specifically designed for web app security testing. It includes a spider for crawling web app content, a randomness tool for testing session tokens, and an intercepting proxy tool that allows for the inspection, modification, and sending of traffic from the browser to a target. Burp Suite is available for free, making it an essential tool for cybersecurity professionals.
Defendify is an all-in-one cybersecurity product that offers a comprehensive set of protection features, including cybersecurity risk assessments, technology and data use policies, incident response plans, penetration testing, and cybersecurity awareness training. It is a valuable resource for any organization looking to streamline their cybersecurity measures.
Gophish is an open-source toolkit that provides security administrators with the ability to build their own phishing campaigns. It is an essential tool for organizations looking to test their employees’ phishing awareness and foster better security training within their organization.
Have I Been Pwned is a website created by cybersecurity thought leader Troy Hunt, where users can enter their email address to check if their information has been revealed in a data breach. With a database filled with billions of compromised usernames, passwords, and other information, Have I Been Pwned is an essential tool for organizations and individuals looking to assess their security posture.
Kali Linux is a Debian Linux derivative specifically designed for security tasks such as penetration testing, security auditing, and digital forensics. It includes roughly 600 pre-installed programs, each included to help computer security experts carry out a specific attack, probe, or exploit against a target.
Metasploit Framework is a powerful network penetration tool that can be used to test computer system vulnerabilities or break into remote systems. It is widely used by ethical hackers and cybersecurity professionals to probe networks and applications for security flaws and weaknesses. There are free and commercial versions available, with the free version offering more than 1,500 exploits.
Nmap is a free network mapper used to discover network nodes and scan systems for vulnerability. It provides methods to find open ports, detect host devices, fingerprint operating systems, and locate potential backdoors. While Nmap provides users immense power and capability to explore networks, the program has a rather steep learning curve to get over before one becomes truly proficient in using it.
Nikto is a command-line tool useful for uncovering vulnerabilities in web apps, services, and web servers. It is widely used by both blue and red teams that want to quickly scan web servers for unpatched software, misconfigurations, and other security issues. The program also features built-in support for SSL proxies and intrusion detection system evasion.
Open Vulnerability Assessment Scanner (OpenVAS) is an all-in-one vulnerability scanner that comprehensively tests for security holes, misconfigured systems, and outdated software. Its capabilities include unauthenticated and authenticated testing, high-level and low-level internet and industrial protocols, performance tuning for large-scale scans, and a powerful internal programming language to implement any type of vulnerability test.
OSSEC is a free program for cybersecurity professionals that’s been touted as one of the most popular systems for intrusion detection and prevention. It is capable of rootkit detection, system integrity checking, threat alerts, and response. One of OSSEC’s highlights is its comprehensive log analysis tool, empowering users to compare and contrast log events from many different sources.
Managing passwords securely is an essential step in the security of any system. Password managers such as KeePass, Bitwarden, and Psono make it possible to safely store all passwords together so a user only needs to remember one master key rather than dozens of unique passwords.
PfSense is a firewall/router software that can be installed on either a physical computer or virtual machine to protect networks. It is based on the FreeBSD OS and has become one of the most popular open source firewall/router projects available.
P0f is a powerful network-level fingerprinting and forensics program designed for stealth. It is capable of identifying fingerprints and other vital information without network interference, making it nearly impossible to detect and even harder to block. It is a favorite tool for ethical hackers and cybercriminals alike.
The free cybersecurity tools outlined above are essential for any organization looking to bolster their security measures. From wireless security and web app testing to phishing assessment and vulnerability scanning, these tools provide cybersecurity professionals with the ability to discover and fix any points of weakness in computer systems, all at no cost. With the ever-increasing threat landscape, it’s imperative that organizations take advantage of these free resources to ensure their systems are adequately protected from cyber threats.
