System and daemon configuration files- It is very important to restrict rights to system and daemon configuration files to restrict users from editing the contents, it may not be advisable to restrict read permissions, but restricting write permissions is a must. To do you can change the permissions of the file to 700.

To remedy this you will want the directory to have the drwx_ (700) permissions, so lets say we want to enforce the correct permissions on the user user1\'s home directory that can be done by issuing the command chmod 700 /home/user1.īootloader configuration files- If you decide to implement password to boot specific operating systems then you will want to remove read and write permissions from the configuration file from all users but root. Home directories- The users\' home directories are important because you do not want other users to be able to view and modify the files in another user\'s documents of desktop. So I will show you some documents and folders that you want to focus on and show you how the optimal permissions should be set. You use the chown command to change owner and group assignments, the syntax is simplechown owner:group filename, so to change the owner of file1 to user1 and the group to family you would enter chown user1:family file1.

I have made several references to Owners and Groups above, but have not yet told you how to assign or change the Owner and Group assigned to a file or directory. So to set a file to permissions on file1 to read _rwxr_, you would enter chmod 740 file1. You will need to include the binary permissions for each of the three permission groups. You add the numbers to get the integer/number representing the permissions you wish to set. The numbers are a binary representation of the rwx string. The first number represents the Owner permission the second represents the Group permissions and the last number represents the permissions for all other users. To set the permission using binary references you must first understand that the input is done by entering three integers/numbers.Ī sample permission string would be chmod 640 file1, which means that the owner has read and write permissions, the group has read permissions, and all other user have no rights to the file. Now that you understand the permissions groups and types this one should feel natural. Using Binary References to Set permissions

To add the permissions above you would invoke the command: chmod a+rw file1Īs you can see, if you want to grant those permissions you would change the minus character to a plus to add those permissions. To make this modification you would invoke the command: chmod a-rw file1
Now we want to remove the read and write permissions from the all users group. So for an example, lets say I have a file named file1 that currently has the permissions set to _rw_rw_rw, which means that the owner, group and all users have read and write permission. The potential Assignment Operators are + (plus) and - (minus) these are used to tell the system whether to add or remove the specific permissions. To explicity define permissions you will need to reference the Permission Group and Permission Types. You can assign the permissions explicitly or by using a binary reference as described below. When in the command line, the permissions are edited by using the command chmod.
The last piece is the Owner and Group assignment formatted as Owner:Group. The third set of three characters (rwx) is for the All Users permissions.įollowing that grouping since the integer/number displays the number of hardlinks to the file. The second set of three characters (rwx) is for the Group permissions. The following set of three characters (rwx) is for the owner permissions. The first character that I marked with an underscore is the special permission flag that can vary. The permission in the command line is displayed as: _rwxrwxrwx 1 owner:group You can view the permissions by checking the file or directory permissions in your favorite GUI File Manager (which I will not cover here) or by reviewing the output of the \"ls -l\" command while in the terminal and while working in the directory which contains the file or folder.
