Kali Linux: The Best Penetration Testing Tools

Kali is a Linuxbased operating system that was designed for penetration testing and security auditing. It contains over 600 different tools that can be used for security assessments, including password crackers, exploit frameworks, and network scanners. With operating system having such a high level of popularity owing to it’s opensource nature, easy customization and freely available codes, it is easy to see why ethical hackers find Kali Linux to be helpful.  

As mentioned earlier, with over 600 tools under it’s arsenal, we have opted to list out and discuss some of the best pen testing tools below. We will also provide instructions on how to use these tools to identify and exploit security vulnerabilities. 

1. Metasploit

Metasploit provides a platform for automated penetration testing, giving users a quick and easy way to find weak spots in their systems and defend against potential attacks. Beyond vulnerability scanning, Metasploit can also be used to run simulations of realworld attacks, helping organizations to stay one step ahead of wouldbe attackers.

Whether you are just starting with penetration testing or are an experienced professional looking to upgrade your security capabilities, Metasploit is an essential tool that no security professional should be without.

Pros of Metasploit:

  • Ease of use
  • Automated penetration testing
  • Vulnerability scanning
  • Realworld attack simulations

Cons of Metasploit

  • Difficult to learn for beginners

2. John the Ripper

John the Ripper is a powerful tool used by information security professionals to brute force passwords. Brute force attacks are typically done when a hacker is trying to guess or crack a password, and they utilize various methods such as attempting common words or phrases, as well as character combinations and permutations.

John the Ripper is one of the most widely recognized and trusted tools for conducting these types of attacks, with advanced analytical capabilities and multiple attack modes.

Pros of John the Ripper:

  • Fast and effective password cracking
  • Advanced analytical capabilities
  • Multiple attack modes

Cons of John the Ripper:

  • Not as userfriendly as some other tools
  • Can be difficult to install and set up

3. Wireshark

Wireshark can be used to track down problems in the network, such as slow performance or intermittent connectivity issues. It can also be used to monitor traffic for unusual activity, such as denialofservice attacks or unauthorized access.

In addition, Wireshark can be used to examine encrypted traffic, such as SSH or HTTPS, to ensure that the data is properly encrypted and decrypted. Wireshark is a vital tool for anyone responsible for managing or securing a network.

Pros of Wireshark:

  • It can track down problems within any network systems.
  • Monitor traffic for unusual activity
  • Examine encrypted traffic

Cons of Wireshark:

  • Can be difficult to learn for beginners
  • GUI can be overwhelming

4. Nmap

Nmap is a powerful network scanning tool that allows users to quickly and easily gain information about the systems and devices connected to their network. With this tool, users can identify open ports, discover which services are running on those ports, and locate hosts that are vulnerable to various attacks.

Whether you are an IT professional performing regular network maintenance or just someone who wants to learn more about the systems in your home or office, Nmap is a useful tool that can help you achieve your goals.

Pros of Nmap:

  • Quick and easy network scanning
  • Identification of open ports and services running on them
  • Locate vulnerable hosts. 

Cons of Nmap:

  • Can be difficult to learn for beginners
  • Advanced features can be overwhelming

Instruction On How To Use Kali Linux Tools

In order to use Kali Linux tools for cloud penetration testing, you need to first install the operating system using a CD or USB. Once you have installed Kali, you need to boot into the live environment.

Once the installation is complete, the variety of tools included in Kali are available to you for use. If you want to conduct a port scan, you can use the Nmap tool or to brute force passwords, you can make use of John The Ripper. There are a wide variety of other tools that you can use for finding and exploiting vulnerabilities as mentioned above.

Once you’ve identified the entry points into the system, you can start testing for vulnerabilities. In testing, the very initial step involves the identification of entry points into the system. This includes any open ports or exposed services. 

Next, you need to try to gain access to the system using these entry points. Once you’ve gained access, you can start enumerating information about the system, such as users, groups, and files. Finally, you can try to escalate your privileges and gain full control of the system.

Which Kali Linux Tool Is the Best?

Many argue that out of all the Kali Linux tools available for penetration testing,  Metasploit often wins the prize of being the best. It provides a comprehensive platform for identifying and exploiting potential security risks.

Additionally, John the Ripper is also a great tool for bruteforcing passwords and retrieving sensitive data. And finally, Wireshark is an essential tool for anyone responsible for managing or securing a network. So, if you are looking for the best Kali Linux tools for penetration testing, these three should be on your list.


As you can see, Kali Linux provides a wealth of powerful tools for penetration testing. While each tool has its pros and cons, the three tools mentioned above are essential for any security professional. We hope this was helpful. While some of these tools can be difficult to learn for beginners, they are essential for anyone looking to upgrade their security capabilities. So, if you are ready to take your penetration testing to the next level, Kali Linux is a great place to start.
