FCBGuard software http://oracleongpu.com/fcbguard/ provides the ability to prevent unauthorised AS SYSDBA login attempt to a database. This is implemented via mandatory USB security key/token/card (call it any way you like it) presence. In order to successfully perform an AS SYSDBA login, database administrator must have a properly configured and database-registered USB security key. Without such a key, any attempt to log in will result in a process kill. The main purpose of the above is to prohibit the root user from being oracle and connecting to the database.


FCBGuard is a free, partially closed software. You can use it in any way you like preserving copyright notice.

How it works

There are a web page and an attached intro.txt file for more details. See below for a brief description.
