In the Linux operating system, each file has attributes that determine who can read, write, or execute a given file. These attributes are called file access rights.
Why do I need access rights in Linux
Access rights in Linux are an important security mechanism that allows you to restrict access to files and directories only for those users who need it. This allows you to protect confidential information and prevent unauthorized access to the system and its files.
In Linux, as in any other multiuser system, different users have different access rights to files and directories. This means that each user can have his own files and directories that only he has access to, and can also be restricted in access to files and directories that belong to other users.
Access rights may restrict the ability of users to work with files and directories, for example, prohibit the deletion or modification of files to which the user does not have full access. This helps prevent accidental deletion or modification of important system files, which can lead to unpredictable consequences for the operation of the system.
Access keys in Linux are an important security mechanism that helps protect the system and its files from unauthorized access and prevents accidental user errors when working with files and directories.
Access rights by category
Access rights in Linux are divided into three types:
the owner of the file (Owner)group (Group)other users (Others)
Each file in Linux has a set of access rights that determines who can perform what actions with this file. For example, the owner of a file may have the right to read, write and execute the file, a group may have the rights to read and execute the file only, and other users may have the right to read the file only.
File permissions in Linux can be changed using the chmod command. With this command, you can set specific access rights for each type of user (owner, group, and other users).
