Goal
By default users that are able to logon as the 'oracle' user on the unix/linux box are able to login to the database with administrator privileges via the command 'sqlplus / as sysdba'.
This form of authentication relies on the feature called 'Operating System Authentication' - No password is required for the user 'oracle'.
You may want to disable this authentication, and if any operating system user tries to login to the database instance, the user should be forced to use the command 'sqlplus sys@as sysdba' and supply the correct password. How would that be possible if at all?
