In Linux, user access controls and user Permissions
Let’s first comprehend how user permissions and access controls function in Linux before we begin the process of creating a new user account.
Understanding User Permissions and Access Controls
Each file and directory in Linux has a set of permissions that control who can access them and what actions they can take. Read, write, and execute are the three categories of these permissions.
User accounts in Linux are linked to a set of permissions that decide what actions users can perform on the system. New user accounts are only allowed to access their own home directory by default and have restricted permissions.
Setting User Permissions and Access Controls
To set appropriate permissions and access controls for a new user account, you can use the chmod
and chown
commands. On your Linux system, you can modify the permissions and ownership of files and directories using these commands.
Use the following command, for instance, to give a new user access to a particular directory:
sudo chmod urwx /path/to/ directory
This command gives the new user access to the directory’s permissions, write, and execute them.
Types of User Permissions
There are three different types of permissions in Linux:
- Read (r): Let users view a file or directory’s contents.
- Write (w): Let users modify a file or directory’s contents.
- Execute (x): Let users access directories or run a file.
Changing User Permissions
To change the permissions of a file or directory, you can use the chmod
command followed by the desired permission code. You can use the following command, for instance, to grant a user access to and write permissions to a file:
sudo chmod urw /path/to/ file
The user reads and writes the file with the aid of this command.
Changing User Ownership
To change the ownership of a file or directory, you can use the chown
command followed by the desired owner and group. You can use the following command, for instance, to convert the file’s owner to a new user:
sudo chown newuser /path/to/File
This command transforms the file’s owner into “newuser.”
Best Practices for User Permissions and Access Controls
When setting user access controls and user permissions in Linux, it’s crucial to adhere to best practices. The following advice will help you:
- To prevent unauthorized access, always make permissions as restrictive as you can.
