 ====== Permissions ======
-Here is a very good article on unix permissions ((http://www.grymoire.com/Unix/Permissions.html)).
+[[http://www.grymoire.com/Unix/Permissions.html|Read this first]].
+===== Securing a directory =====
+You're here because you heard that this would a good idea. There are going to be many ways to ensure a directory is 'secure', but that will depend on your requirements.
+I will assume that you are the only person that will need access to said directory. I also will not try to explain unix permissions to you. If you want to know more I suggest you read the link at the top of this page. Follow along below to create a directory that only you will be able to access.
+Given a directory ''%%foo%%'' we can do the following:
+<code>
+chown $USER:$USER foo
+</code>
+$USER will translate to your username, but we recommend you actually type out your username.
+This will set the user and the group to $USER.
+Now make sure that only the user field can has access to the directory.
+<code>
+chmod 700 foo
+</code>
+==== I have a directory structure full of files and I want to ensure no one else can read them ====
+I got your back.
+<code>
+chmod -R go-rwx foo
+  -R: recursive.
+  g: select group permission
+  o: select other permission
+  -: remove
+  r: read permission
+  w: write permission
+  x: execute permission
+</code>
+We are asking ''%%chmod%%'' to remove read, write, and execute permissions on the group and other permission fields.
