When you say you only do checking if "is_logged_in" is set, is it done on another controller? As from the code you've given, you do no checking. Possibly store the users Email/Username and Password (Obviously, using the various encryption methods offered in CI) in the session and, if they're set, make sure the combination exists with the User Database.
