Hi,
I would like to prevent users which can "su" to oracle user account (root users) to logon to oracle as sysdba.
I know I can do this by setting SQLNET.AUTHENTICATION_SERVICES=NONE in sqlnet.ora but it can be changed.
I can monitor hash of sqlnet.ora file and send a mail if it change, however this approach also has weaknesses.
 
Regards,
Boris
