Of course, nothing prevents you from creating new unprivileged accounts on your system. But being root for your daily work on Kali will remove that safety net (as it would on any Linux system, by the way). The file permissions are set in such a way that an “ordinary” user couldn’t endanger the system as a whole. And there are potentially hundreds of such critical files on a typical Linux system. In some cases, you may alter your system without noticing any obvious changes until the next reboot or the next update – when it will suddenly break. And even things you don’t want.įor example, when exploring your system you might inadvertently edit some critical files like /etc/passwd or some file in the directory /etc/grub.d/ in such a way that your system will become unusable. You have to understand that being root means there are basically no permissions checks on your machine. On the other hand, on a default Kali Linux system, the only installed user is root and you have to work under that identity all the time. For computer maintenance or to perform administrative tasks, some users may temporarily endorse the privileged identity “root” that gives them super-powers on the host. On a typical Unix-like system, users work as unprivileged users, with access to their own files, but without the ability to tamper with the system or other users’ files. But once again, is it really wise to check your mail as root on a machine you will use for security auditing? To download Kali Linux, I went to the official download page and followed the first download link on that page.Īnd indeed it will. Downloading Kali Linux- and checking the image integrity It is just a special distribution that makes the tasks it’s specifically designed for easier, while consequently making some other tasks more difficult. In other words, whatever’s your goal, you don’t have to use Kali. The difference is that Kali is pre-packaged with those tools and the default settings were chosen according to the intended use cases of that distribution, rather than, say, to fit the needs of the typical desktop user. So Kali Linux does not offer something unique in the sense that most of the tools it provides could be installed on any Linux distribution. Simply put, it’s a Linux distribution packed with security-related tools and targeted toward network and computer security experts.Ī Linux distribution is nothing more than a bundle containing the Linux kernel, a set of core utilities and applications and some default settings. To quote the official web page title, Kali Linux is a “Penetration Testing and Ethical Hacking Linux Distribution”. It’s a Debian-based rewrite of their previous Knoppix-based digital forensics and penetration testing distribution BackTrack. Kali Linux is developed by the security firm Offensive Security.
