Creating and using Oracle Database Vault factors


Factors can also play an important role in enforcing security in Oracle Database Vault. A factor is a variable or an attribute, something similar to application context attributes. A factor can represent a user session, session identifier, module, IP address, and more. You can use factors for conditioning and restricting user authentication, and to build additional restrictions on data access based on their values and attributes.

Getting ready

In this recipe, we will replace the rule expressions Evaluate VW_AMERICA user and Evaluate VW_EUROPE user with the default Session_user factor.

How to do it...

Oracle Database Vault provides build it factors that can be used alone or combined to enforce different types of evaluations:

  1. Connect as the ODVA_OWNER user and select the session user from the dvf.f$session_user factor function:

    SQL> conn odva_owner
    Enter password:
    SQL> select dvf.f$session_user from dual;
    
    F$SESSION_USER
