- Advanced Penetration Testing tools.In the Kali Linux, more than 600+ super amazing advanced Penetration’ Testing tools are incorporated. The tools of BackTrack Linux which are not up to the mark or repeated in many ways has been replaced in the Kali Linux system with the advanced Penetration testing tools.
- Ultimate free Linux tool.The Kali Linux system is totally free like the BackTrack Linux and will always offer their users the free life time services. This is huge plus factor which forces people to use this system.
- Open sourced Git tree.This Kali Linux is openly sourced system and can be easily accessed by the users. All the codes in the Kali Linux can be viewed easily by the anyone and the open development tree makes easy to view the development of coding at every step.
- FHS support.Kali adheres to the File-system Hierarchy Standard, allowing Linux users to easily locate binaries, support files, libraries, etc. This is the very important feature of the Kali Linux that makes it stand out among the other Linux systems.
Kali Linux is specifically geared to meet the requirements of professional penetration testing and security auditing. To achieve this, several core changes have been implemented in Kali Linux which reflect these needs:
- Single user, root access by design:Due to the nature of security audits, Kali Linux is designed to be used in a “single, root user” scenario. Many of the tools used in penetration testing require escalated privileges, and while it’s generally sound policy to only enable root privileges when necessary, in the use cases that Kali Linux is aimed at, this approach would be a burden.
- Network services disabled by default:Kali Linux contains sysvinit hooks which disable network services by default. These hooks allow us to install various services on Kali Linux, while ensuring that our distribution remains secure by default, no matter what packages are installed. Additional services such as Bluetooth are also blacklisted by default.
- Custom Linux kernel:Kali Linux uses an upstream kernel, patched for wireless injection.
- A minimal and trusted set of repositories: given the aims and goals of Kali Linux, maintaining the integrity of the system as a whole is absolutely key. With that goal in mind, the set of upstream software sources which Kali uses is kept to an absolute minimum. Many new Kali users are tempted to add additional repositories to their sources.list, but doing so runs a very serious risk of breaking your Kali Linux installation.
