chown user filename
Provide users or groups with the least amount of privileges required to do their job
chown user file dont forget that you should be owner of the file or root to give privilege to other users to a file
The administrator of the system will establish new rights for users.
Basically just sets access levels of users or classes of users to different content on network devices.
Under least privilege principles, a users should be granted full rights to their own files, e.g. create, read, write, modify, delete, execute, etc. The exact rights will depend some on what the underlying OS is. Beyond that, users may also be granted limited privileges to other files to enable them to perform their responsibilities. If they are a member of another group, they may be granted read, write, or execute privileges for "group" files. The way the privileges are assigned will depend on the access control model being used. Will it be Mandatory Access Control, Discretionary Access Control, Role Based Access Control, or some other model? Depending on the model, You may have to define other privileges like "take ownership", "give ownership", or "assign classification". You usually would only want to allow a user to have the "give ownership" rights for their own files, but have a higher arbiter having the "assign classification" rights.
