How to Pick Your Best Penetration Testing Tools
When trying to find the penetration testing tool that will best fit your needs, you should start by thinking about the types of tests on which you want to focus.
Some tools have specific areas of strength, while others offer versatility. You may want to combine your penetration testing tool with other security processes and tests to achieve the highest level of security. We’ll break down some of the specific features you may want in a pen test tool.
Port Scanning and Connection Scanning
When your network has open ports or unsecured WiFi connections, hackers may be able to introduce malicious code to your network.
Open ports alone don’t always represent security issues, as they offer a means of accepting communication. But when not secured properly, they can create a pathway for potential attackers to take advantage of other security flaws that exist in the network.
Nmap has a particular strength in monitoring open ports for any vulnerabilities. When you want to monitor the security flaws that may exist with your WiFi connections and overall WiFi setup, Aircrack-ng is an outstanding choice.
Network Sniffing and Traffic Monitoring
Network sniffing refers to the process of collecting and monitoring traffic that moves across your network. A penetration testing tool often passively monitors the most active applications on the network that are using this traffic.
The tool looks for any exposed credentials moving across the network through the apps. This would indicate a potential security risk. Some pen test tools also monitor for sensitive data moving across the network in an unsafe manner.
Burp Suite is one of the strongest penetration testing tools for testing traffic passing through web applications on your network.
Password Strength Measuring and Cracking
When you secure your data and network apps through passwords, the level of security you have is only as good as the strength of the passwords. Hackers looking to exploit a network may attempt to steal or crack passwords to gain access.
A penetration testing tool that focuses on measuring password strength through running simulated attacks on passwords can discover any weak areas. John the Ripper is one of the strongest password cracking penetration testing tools available.
Overall Network Vulnerability Scanning
Some penetration testing tools don’t have a single primary area of focus. They deliver versatility and the ability to test a wide range of items on the network.
Kali Linux can deliver a wide range of penetration testing tools, but its nonstandard interface may leave some people looking elsewhere.
Our two favorite penetration testing tools that offer the highest level of versatility are Metasploit and Wireshark.
