Hi and welcome to LQ.
In Linux every file (folders included) belong to one user and rights for reading or writing it can be granted to this user, the users to which this one belongs to, or all users.
So to protect the folder you will have to use these commands: "chown" to change to owner if needed and "chmod" to set up the permissions. See "man chmod" and "man chown" to know more. Optionally these commands can be recursive, i.e. thees settings can apply to all sub-foldesr and files in the folder.
