Rohit Srivastava

IT Manager at PRATHAM SOFTWARE PRIVATE LIMITED

Sometimes, I do face challenges. There's an issue where sometimes during the initial installation, it doesn't install properly. It gives multiple errors like packages not installing, so we have to install those tools separately. For instance, if we want to install a network or other tools, we have to install those complete toolkits manually. So, the challenge is with the initial setup, where I sometimes get errors. Regarding wireless attacks, OS attacks, and social engineering... the tools should be easier to learn because I know everything very well, but some people in my team struggle to understand. If there were GUI interfaces for the tools, it would help me guide my team in using them step-by-step. Command lines are very difficult for other team members who know the tool's purpose but not the Linux commands. GUI interfaces need more improvement. So, the UI interface needs improvement to make it more visible and easier for users. Expert users can do everything without any issues, but new users will struggle.

Pre-installed tools can provide basic training and security measures, which is helpful. However, these tools may not be sufficient to secure your workload fully. That's why it's important to complement them with other specialized security tools to enhance your overall security. Before using Kali Linux, make sure you know its pros and cons. It's a good system to learn because it's the best choice for some situations. It has default firewall settings that block everything by default. It's up to the user to decide how much they want to open up. Learning Kali Linux takes time because it relies on command-line tasks instead of graphical interfaces. Practice is key to becoming comfortable with it.

I have found the tool to be the most effective when we want to run the vulnerability assessment provided by the solution in our company for certain websites and applications so that we can find or detect issues. In our company, Kali Linux is used for most of the use case scenarios where vulnerability assessment is required. The areas I found to be the most effective from the perspective of security tasks are Zed Attack Proxy (ZAP), Metasploit, Wireshark, Nikto, and SQLMAP. There have been a lot of benefits from the pre-installed tools in the product, in terms of security auditing part in our company. There are also other operating systems on which you can run Kali Linux, where users are provided with a massive range of tools like BlackArch Linux and ParrotOS, which are useful for certain use cases. The product is good to start with, and it is good for penetration testing and vulnerability assessment. It is good for those who want to go into the line of website security. New users of the product should know the basics of Linux to be able to use the solution because it is an area that could be hard for many. The value derived from the use of the product in our company stems from the results it provides us. The reason to use the product is to get answers when you run a vulnerability assessment from a security perspective. The product provides an outcome that can be used to access the security posture of an application, and it can also help you find loopholes. In general, it can be used to test applications. I rate the tool a ten out of ten.

It simplifies security tasks with tools like SQLMap and Burp Suite, offers a user-friendly interface, and includes advanced security measures for robust system protection. Its stability, multi-user capability, and low maintenance make it highly effective for network testing, penetration testing, and security assessments.

"In general, Kali Linux is used for hosting applications, developing new applications, and operating systems. It's also used in containers and nodes. The tool offers a smaller footprint than Windows because it lacks the functionality of graphical user interfaces. One advantage of Kali Linux is its lower maintenance requirements than Windows, with slower update cycles and easier maintenance procedures."
"The most effective features of Kali Linux include its stability as a Linux operating system, its flexibility in configuring resources such as partitions, its powerful and stable file system, and its multi-user capability, which allows for setting user privileges and rights. Additionally, Kali Linux provides access to a wide range of free and open-source applications for testing and development purposes."
"The solution's most valuable feature is that it is very easy to use."

Room for Improvement

Kali Linux needs automation for upgrades, integration of AI and GPT features, improved security, and a more user-friendly interface with easy-to-use GUI for tools. The installation process needs to be faster, especially within virtualized environments, and include fewer errors during the initial setup. Learning resources and features in the free version should be enhanced. Addressing UI issues in older versions and expanding application options are also necessary improvements.

"The tool is already stable and well-developed, so there's minimal feedback for enhancement or change. However, it should improve security, which is crucial, especially with the increasing use of Kali Linux in cloud environments."
"The tool is slightly difficult to learn."
"From an improvement perspective, it should be made possible for users to learn about the product easily."
