This article will explain in detail what is the most authorized account in linux. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

The most privileged account in linux is root. Root, also known as root user, is the only superuser in Unix and UNIX-like systems, as well as Android and iOS mobile device systems; root has all the permissions of the system, and if the root password is disclosed, it will cause the data of all users on the entire computer to be completely stolen.

The most privileged account in linux is root.

Root, also known as root user, is the only super user in Unix (such as Solaris, AIX, BSD) and UNIX-like systems (such as Linux, QNX, etc.), as well as Android and iOS mobile device systems, named because it can read, write and perform operations on the root directory.

It is equivalent to SYSTEM (XP and below) / TrustedInstaller (Vista and above) users in Windows system. It has the highest privileges in the system, such as starting or stopping a process, deleting or adding users, adding or disabling hardware, adding files or deleting all files, and so on.

One of the reasons why root is not recommended is for security reasons.

Root has all the permissions of the system, and the disclosure of the root password is enough to cause the whole computer to be completely controlled by the person who stole the root password. Having the root password means having all the data of all the users on this computer.

Some tasks must be performed by root, such as deleting the system's built-in application.

However, root is not recommended in Unix or Linux systems, which constitutes a contradiction. As a result, a practice of sudo is to use su to elevate rights when necessary, that is, to grant part of the permissions of system management to ordinary users, and only when these users need higher permissions, they are allowed to temporarily use root commands to manage the system.

By default, the root directory (/ root) of root is not accessible to other users, which enhances the security of the entire system to some extent, but not entirely.

The security of Unix, Linux, and Android depends more on its high configurability, that is, the security of Unix or Linux depends more on the system administrator than on the Unix or Linux system itself.

The general mode is that Unix, Linux and Android provide a sound security mechanism, and the system administrator formulates the corresponding security policies according to the actual needs, and deploys these security policies.

The "mechanism" is what you can do and what you can't do, and the "strategy" is what you want to do and don't do. On the other hand, the security policy and security mechanism of Windows are quite chaotic. Windows itself is too dependent on security policy, which leads to the system administrator being tied up in many times, and the loss outweighs the gain.
