Database Vault in Oracle

 Database Vault in Oracle

Database Vault is a feature in Oracle Database that provides security and access control capabilities for sensitive data. Database Vault allows you to define and enforce security policies that restrict access to sensitive data and protect against unauthorized changes.

Here is an example of using Database Vault to create a secure application role:

BEGIN

   DBMS_MACADM.CREATE_APPROLE(

      role_name => 'my_app_role',

      description => 'Application role for secure access',

      password => 'my_password',

      failover => TRUE

   );

   DBMS_MACADM.ADD_AUTH_TO_APPROLE(

      role_name => 'my_app_role',

      auth_name => 'my_policy',

      auth_option => DBMS_MACUTL.GRANT,

      auth_grantee => 'my_user'

   );

END;

/

This example creates an application role named "my_app_role" with a password of "my_password". The role is granted access to a security policy named "my_policy", which has been defined to restrict access to sensitive data. The policy is applied to the "my_user" user, which is the grantee of the policy.
