3 Getting Started with Oracle Database Vault

Before you can start using Oracle Database Vault, you must configure and enable it with the Oracle database.

3.1 About Configuring and Enabling Oracle Database Vault in Oracle Database

Oracle Database includes Database Vault when you choose to include a default database in the installation process, but you must configure and enable it before you can use it.

Oracle Database includes Database Vault when you choose to include a default database in the installation process, but you must configure and enable it before you can use it. The configuration and enablement process enables Oracle Label Security if it is not already enabled. Oracle Label Security is required for Oracle Database Vault but it does not require a separate license unless you begin using Oracle Label Security separately and create Oracle Label Security policies.

Oracle Database includes Database Vault when you choose to include a default database in the installation process, but you must configure and enable it before you can use it. If you create a custom database, then you can use DBCA to install and enable Database Vault for it. The registration process enables Oracle Label Security if it is not already enabled. Oracle Label Security is required for Oracle Database Vault but it does not require a separate license unless you begin using Oracle Label Security separately and create Oracle Label Security policies. This procedure applies to the CDB root, application root, and the current pluggable database (PDB), as well as to both single-instance and Oracle Real Application Clusters (Oracle RAC) installations. In a multitenant database, Database Vault must be configured with the CDB root before any of the PDBs can configure Database Vault.

As part of the configuration process, you created the Database Vault administrative accounts. These are accounts that hold the Database Vault roles DV_OWNER and DV_ACCTMGR. Use these accounts initially to provision the roles to named users with administrative privileges. Maintaining a backup account will allow you to recover from the named user losing or somehow misplacing their credentials because SYS will not be able to reset these passwords for users with these roles.

Note:

If you upgraded from a release earlier than Oracle Database 12c, then you disabled Oracle Database Vault to perform the upgrade. After the upgrade process is complete, then you must configure and enable Oracle Database Vault again.

If you are migrating a non-Database Vault-enabled Oracle database from a release earlier than release 12c, then you must perform a manual installation of Database Vault.

3.2 Configuring and Enabling Oracle Database Vault

You can configure and enable Oracle Database Vault based on several scenarios.

Parent topic: Getting Started with Oracle Database Vault

3.2.1 About Configuring and Enabling Database Vault

You must configure and enable Oracle Database Vault in the CDB root before you can perform the same action in any of the associated PDBs.

The common users who have been assigned the DV_OWNER and DV_ACCTMGR roles in the CDB root can also have the same role in the PDBs. PDBs can have Database Vault configured and enabled using the same common users or use separate PDB local users. The DV_ACCTMGR role is granted commonly to the common user in the CDB root. You can grant DV_OWNER locally or commonly to the CDB root common user when you configure and enablement Database Vault with the CDB root. Granting DV_OWNER locally to the common user prevents the common DV_OWNER user from using this role in any PDB.

Parent topic: Configuring and Enabling Oracle Database Vault

3.2.2 Configuring and Enabling Database Vault in the CDB Root

You configure and enable Oracle Database Vault with common users who will use the Database Vault-enforced roles in the CDB root.

Before you begin, Oracle recommends that you ensure that all database-related objects are valid. You can use the UTL_RECOMP PL/SQL package to check the validity of objects. See Oracle Database PL/SQL Packages and Types Reference.
  1. Log into the root of the database instance as a user who has privileges to create users and grant the CREATE SESSION and SET CONTAINER privileges.

    For example:

    sqlplus c##dba_debra
Enter password: password
  2. Select user accounts (or create new users) that will be used for the Database Vault Owner (DV_OWNER role) and Database Vault Account Manager (DV_ACCTMGR role) accounts.

    Prepend the names of these accounts with c## or C##. For example: 

    GRANT CREATE SESSION, SET CONTAINER TO c##sec_admin_owen 
  IDENTIFIED BY password CONTAINER = ALL;
GRANT CREATE SESSION, SET CONTAINER TO c##dbv_owner_root_backup 
  IDENTIFIED BY password CONTAINER = ALL;
GRANT CREATE SESSION, SET CONTAINER TO c##accts_admin_ace 
  IDENTIFIED BY password CONTAINER = ALL;
GRANT CREATE SESSION, SET CONTAINER TO c##dbv_acctmgr_root_backup 
  IDENTIFIED BY password CONTAINER = ALL;

    This specification grants two system privileges, creates the accounts if they do not exist, assigns a password, and does this so all the users have access to the CDB and all PDB databases.

    • Create the primary accounts (c##sec_admin_owen and c##accts_admin_ace) if these do not already exist for the new roles, DV_ADMIN and DV_ACCTMGR.
    • Replace password with a password that meets the password complexity requirements of the user's profile.
  3. Connect to the root as user SYS with the SYSDBA administrative privilege 
    CONNECT SYS AS SYSDBA
Enter password: password
  4. Configure the two backup Database Vault user accounts.
    For example:
    BEGIN
 CONFIGURE_DV (
   dvowner_uname         => 'c##dbv_owner_root_backup',
   dvacctmgr_uname       => 'c##dbv_acctmgr_root_backup',
   force_local_dvowner   => FALSE);
 END;
/
    In this example, setting force_local_dvowner to FALSE enables the common users to have DV_OWNER privileges for the PDBs that are associated with this CDB root. Setting it to TRUE restricts the common DV_OWNER user to have the DV_OWNER role privileges for the CDB root only. If you grant DV_OWNER locally to the CDB root common user, then that user cannot grant the DV_OWNER role commonly to any other user.
  5. Run the utlrp.sql script to recompile invalidated objects in the root. 
    @?/rdbms/admin/utlrp.sql

    If the script provides instructions, follow them, and then run the script again. If the script terminates abnormally without giving any instructions, then run it again.

  6. Connect to the root as the primary Database Vault Owner user that you just configured.

    For example:

    CONNECT c##dbv_owner_root_backup
Enter password: password
  7. Enable Oracle Database Vault using one of the following commands:

    • To enable Oracle Database Vault to use regular mode:

      EXEC DBMS_MACADM.ENABLE_DV;

    • If every associated PDB will need to have Database Vault enabled in this database, then use the following command. (You will need to enable each of these PDBs after you complete this procedure.) PDBs that do not have Database Vault enabled will be in restricted mode after the database is restarted and until Database Vault is enabled in the PDB:

      EXEC DBMS_MACADM.ENABLE_DV (strict_mode => 'y');
  8. Connect with the SYSOPER administrative privilege.
    CONNECT / AS SYSOPER
  9. Restart the database.
    For a single-instance database:
    SHUTDOWN IMMEDIATE
STARTUP

    If you are in an Oracle Real Application Clusters (Oracle RAC) environment, then you can perform an Oracle RAC rolling enablement.

  10. Connect with the SYSDBA administrative privilege.
    CONNECT / AS SYSDBA
  11. Verify that Oracle Database Vault and Oracle Label Security are installed and enabled.
    SELECT * FROM CDB_DV_STATUS;
SELECT * FROM CDB_OLS_STATUS;
  12. Connect as the backup DV_OWNER user and then grant the DV_OWNER role, including the WITH ADMIN OPTION clause, to the primary DV_OWNER user that you created earlier.

    For example:

    CONNECT c##dbv_owner_root_backup
Enter password: password

GRANT DV_OWNER TO c##sec_admin_owen WITH ADMIN OPTION CONTAINER = ALL;
  13. Connect as the backup DV_ACCTMGR user and then grant the DV_ACCTMGR role, including the WITH ADMIN OPTION clause, to the backup DV_ACCTMGR user.

    For example:

    CONNECT c##dbv_acctmgr_root_backup
Enter password: password

GRANT DV_ACCTMGR TO c##accts_admin_ace WITH ADMIN OPTION CONTAINER=ALL;
  14. Store the two backup account passwords in a safe location such as a privileged account management (PAM) system in case they are needed in the future.

3.2.3 Configuring and Enabling Database Vault Common Users to Manage Specific PDBs

You must configure and enable Oracle Database Vault in the root first, then in the PDBs afterward.

If you try to configure and enable in a PDB first, then an ORA-47503: Database Vault is not enabled on CDB$ROOT error appears.
  1. If you have not already done so, then identify or create named common user accounts to be used as the Database Vault accounts along with associated backup accounts.
  2. Ensure that you have configured and enabled Oracle Database Vault in the CDB root and that the DV_OWNER role was granted commonly to the common user.
  3. Connect to the PDB as an administrator who is local to the PDB.
    For example:
    CONNECT dba_debra@pdb_name
Enter password: password

    To find the available PDBs, query the DBA_PDBS data dictionary view. To check the current PDB, run the show con_name command.

  4. If necessary, open the database. 
    ALTER DATABASE OPEN;
  5. Grant the CREATE SESSION and SET CONTAINER privileges to the users for this PDB.
    For example: 
    GRANT CREATE SESSION, SET CONTAINER TO c##sec_admin_owen CONTAINER = CURRENT;
GRANT CREATE SESSION, SET CONTAINER TO c##accts_admin_ace CONTAINER = CURRENT;
  6. Connect as user SYS with the SYSDBA administrative privilege 
    CONNECT SYS@pdb_name AS SYSDBA
Enter password: password
  7. While still in the PDB, configure the two backup Database Vault user accounts. 
    BEGIN
 CONFIGURE_DV (
   dvowner_uname         => 'c##dbv_owner_root_backup',
   dvacctmgr_uname       => 'c##dbv_acctmgr_root_backup');
 END;
/

    In this example, the force_local_dvowner parameter is omitted because it is unnecessary. All common users who are configured within a PDB are restricted to the scope of the PDB.

  8. Run the utlrp.sql script to recompile invalidated objects in this PDB. 
    @?/rdbms/admin/utlrp.sql

    If the script provides instructions, follow them, and then run the script again. If the script terminates abnormally without giving any instructions, then run it again.

  9. Connect to the PDB as the backup Database Vault Owner user that you just configured.
    For example:
    CONNECT c##dbv_owner_root_backup@pdb_name
Enter password: password
  10. Enable Oracle Database Vault in this PDB.
    EXEC DBMS_MACADM.ENABLE_DV;
  11. Connect to the CDB with the SYSDBA administrative privilege.
    CONNECT / AS SYSDBA
  12. Close and reopen the PDB.
    For example:
    ALTER PLUGGABLE DATABASE pdb_name CLOSE IMMEDIATE;
ALTER PLUGGABLE DATABASE pdb_name OPEN;
  13. Verify that the PDB is configured and enabled for Database Vault and Oracle Label Security.
    CONNECT SYS@pdb_name AS SYSDBA
Enter password: password

SELECT * FROM DBA_DV_STATUS;
SELECT * FROM DBA_OLS_STATUS;
  14. Connect as the backup DV_OWNER user and then grant the DV_OWNER role, including the WITH ADMIN OPTION clause, to the primary DV_OWNER user that you created earlier.

    For example:

    CONNECT c##dbv_owner_root_backup@pdb_name
Enter password: password

GRANT DV_OWNER TO c##sec_admin_owen WITH ADMIN OPTION;
  15. Connect as the backup DV_ACCTMGR user and then grant the DV_ACCTMGR role, including the WITH ADMIN OPTION clause, to the primary DV_ACCTMGR user.

    For example:

    CONNECT c##dbv_acctmgr_root_backup@pdb_name
Enter password: password

GRANT DV_ACCTMGR TO c##accts_admin_ace WITH ADMIN OPTION;
  16. Store the two backup account passwords in a safe location such as a privileged account management (PAM) system in case they are needed in the future.

3.2.4 Configuring and Enabling Database Vault Local Users to Manage Specific PDBs

You must configure and enable Oracle Database Vault in the root first, and then in the PDBs afterward.

If you try to configure and enabale in a PDB first, then an ORA-47503: Database Vault is not enabled on CDB$ROOT error appears.
  1. Log in to the PDB as a user who has privileges to create users and to grant the CREATE SESSION and SET CONTAINER privileges.
    For example:
    sqlplus sec_admin@pdb_name
Enter password: password

    To find the available PDBs, query the DBA_PDBS data dictionary view. To check the current PDB, run the show con_name command.

  2. If necessary, open the database. 
    ALTER DATABASE OPEN;
  3. If you are not using existing local user named accounts for the new Database Vault roles, create new named local user accounts.
    In both cases, you must create backup accounts to hold the Database Vault roles in case the named user loses or forgets their password.
    GRANT CREATE SESSION, SET CONTAINER TO sec_admin_owen 
  IDENTIFIED BY password;
GRANT CREATE SESSION, SET CONTAINER TO dbv_owner_backup 
  IDENTIFIED BY password;
GRANT CREATE SESSION, SET CONTAINER TO accts_admin_ace 
  IDENTIFIED BY password;
GRANT CREATE SESSION, SET CONTAINER TO dbv_acctmgr_backup 
  IDENTIFIED BY password;
  4. Ensure that you have configured and enabled Oracle Database Vault in the CDB root.
    Temporarily connect to the root and then query the DBA_DV_STATUS view. 
    CONNECT SYS / AS SYSDBA
Enter password: password

SELECT * FROM DBA_DV_STATUS;
  5. Connect to the PDB as user SYS with the SYSDBA administrative privilege. 
    CONNECT SYS@pdb_name AS SYSDBA
Enter password: password
  6. While still in the PDB, configure the two backup Database Vault user accounts. 
    BEGIN
 CONFIGURE_DV (
   dvowner_uname     => 'dbv_owner_backup',
   dvacctmgr_uname   => 'dbv_acctmgr_backup');
 END;
/

    In this example, the force_local_dvowner parameter is omitted because it is unnecessary. Database Vault roles are granted locally when configured in a PDB.

  7. Run the utlrp.sql script to recompile invalidated objects in this PDB. 
    @?/rdbms/admin/utlrp.sql

    If the script provides instructions, follow them, and then run the script again. If the script terminates abnormally without giving any instructions, run it again.

  8. Connect to the PDB as the backup Database Vault Owner user that you just configured.
    For example:
    CONNECT dbv_owner_backup@pdb_name
Enter password: password
  9. Enable Oracle Database Vault in this PDB.
    EXEC DBMS_MACADM.ENABLE_DV;
  10. Connect to the CDB with the SYSDBA administrative privilege.
    CONNECT / AS SYSDBA
  11. Close and reopen the PDB. 
    ALTER PLUGGABLE DATABASE pdb_name CLOSE IMMEDIATE;
ALTER PLUGGABLE DATABASE pdb_name OPEN;
  12. Verify that the PDB is configured and enabled for Database Vault and Oracle Label Security.
    CONNECT SYS@pdb_name AS SYSDBA
Enter password: password

SELECT * FROM DBA_DV_STATUS;
SELECT * FROM DBA_OLS_STATUS;
  13. Connect as the backup DV_OWNER user and then grant the DV_OWNER role, including the WITH ADMIN OPTION clause, to the primary DV_OWNER user that you created earlier.

    For example:

    CONNECT dbv_owner_backup@pdb_name
Enter password: password

GRANT DV_OWNER TO sec_admin_owen WITH ADMIN OPTION;
  14. Connect as the backup DV_ACCTMGR user and then grant the DV_ACCTMGR role, including the WITH ADMIN OPTION clause, to the backup DV_ACCTMGR user.

    For example:

    CONNECT dbv_acctmgr_backup@pdb_name
Enter password: password

GRANT DV_ACCTMGR TO c##accts_admin_ace WITH ADMIN OPTION;
  15. Store the two backup account passwords in a safe location such as a privileged account management (PAM) system in case they are needed in the future.

3.2.5 Configuring and Enabling Oracle Database Vault in an Oracle Real Application Clusters Environment

You can configure Oracle Database Vault for an Oracle Real Application Clusters (Oracle RAC) environment, including each Oracle RAC node.

To configure Oracle Database vault for an Oracle RAC environment, you must configure and enable Oracle Database Vault on one node, then restart each of the instance nodes to enable it everywhere. The following procedure assumes that you have a separate Oracle home for each node.
  1. Configure and enable Oracle Database Vault in the CDB root.
  2. Log into the PDB as user SYS with the SYSDBA administrative privilege. 
    sqlplus sys@pdb_name as sysdba 
Enter password: password

    To find the available PDBs, query the PDB_NAME column of the DBA_PDBS data dictionary view. To check the current container, run the show con_name command.

  3. If necessary, open the database. 
    ALTER DATABASE OPEN;
  4. Run the following ALTER SYSTEM statements on each Oracle RAC node: 
    ALTER SYSTEM SET AUDIT_SYS_OPERATIONS=TRUE SCOPE=SPFILE; -- For non-unified auditing environments
ALTER SYSTEM SET OS_ROLES=FALSE SCOPE=SPFILE; 
ALTER SYSTEM SET RECYCLEBIN='OFF' SCOPE=SPFILE; 
ALTER SYSTEM SET REMOTE_LOGIN_PASSWORDFILE='EXCLUSIVE' SCOPE=SPFILE;
ALTER SYSTEM SET SQL92_SECURITY=TRUE SCOPE=SPFILE;
  5. Close and then reopen the PDB. 
    ALTER PLUGGABLE DATABASE pdb_name CLOSE IMMEDIATE;
ALTER PLUGGABLE DATABASE pdb_name OPEN;

3.2.6 Creating a Profile to Protect the DV_OWNER and DV_ACCTMGR Users

A profile provides additional protection for users who have been granted the DV_OWNER and DV_ACCTMGR roles.

Database users who have been granted the DV_OWNER or DV_ACCTMGR roles are considered critical, privileged, accounts. Typically, these accounts should be considered service accounts and exempt from password lockout requirements. Oracle recommends that you create a custom profile that prevents the account from being locked. In addition, you should audit failed login attempts for these Database Vault-related accounts.
  1. Log into the database instance as a user who has the CREATE PROFILE system privilege.
    • For common DV_OWNER and DV_ACCTMGR users: Log in to the root of the database instance.
    • For local DV_OWNER and DV_ACCTMGR users: Log in to the PDB in which you created the users.
  2. Create a profile similar to the following:
    • For common DV_OWNER and DV_ACCTMGR users: In the root, create the profile similar to the following: 
      CREATE PROFILE c##dv_profile limit
FAILED_LOGIN_ATTEMPTS UNLIMITED
PASSWORD_VERIFY_FUNCTION ORA12C_VERIFY_FUNCTION
PASSWORD_LOCK_TIME UNLIMITED
CONTAINER=CURRENT;
    • For local DV_OWNER and DV_ACCTMGR users: In the PDB, create the profile similar to the following: 
      CREATE PROFILE dv_profile limit
FAILED_LOGIN_ATTEMPTS UNLIMITED
PASSWORD_VERIFY_FUNCTION ORA12C_VERIFY_FUNCTION
PASSWORD_LOCK_TIME UNLIMITED
CONTAINER=CURRENT;
  3. Update the DV_OWNER and DV_ACCTMGR user accounts to use this profile.
    • For common DV_OWNER and DV_ACCTMGR users: 
      ALTER USER c##sec_admin_owen PROFILE c##dv_profile CONTAINER=ALL;
ALTER USER c##dbv_owner_root_backup PROFILE c##dv_profile CONTAINER=ALL;
ALTER USER c##accts_admin_ace PROFILE c##dv_profile CONTAINER=ALL;
ALTER USER c##dbv_acctmgr_root_backup PROFILE c##dv_profile CONTAINER=ALL;
    • For local DV_OWNER and DV_ACCTMGR users:
      ALTER USER sec_admin_owen PROFILE dv_profile CONTAINER=CURRENT;
ALTER USER dbv_owner_backup PROFILE dv_profile CONTAINER=CURRENT;
ALTER USER accts_admin_ace PROFILE dv_profile CONTAINER=CURRENT;
ALTER USER dbv_acctmgr_backup PROFILE dv_profile CONTAINER=CURRENT;
  4. Connect as a user who has been granted the AUDIT_ADMIN role.
  5. Create and enable a unified audit policy to track failed logins by any user who has been granted the DV_OWNER or DV_ACCTMGR role.
    • For common DV_OWNER and DV_ACCTMGR users: In the root, create a policy similar to the following:
      CREATE AUDIT POLICY c##dv_logins ACTIONS LOGON;
AUDIT POLICY c##dv_logins BY USERS WITH GRANTED ROLES DV_OWNER, DV_ACCTMGR WHENEVER NOT SUCCESSFUL;
    • For local DV_OWNER and DV_ACCTMGR users: In the PDB, create a policy similar to the following:
      CREATE AUDIT POLICY dv_logins ACTIONS LOGON;
AUDIT POLICY dv_logins BY USERS WITH GRANTED ROLES DV_OWNER, DV_ACCTMGR WHENEVER NOT SUCCESSFUL;

3.2.7 Manually Installing Oracle Database Vault

Under certain conditions, you must manually install Oracle Database Vault.

For example, you must manually install Oracle Database Vault if a release 11g Oracle database without Database Vault is upgraded to release 12c, then converted to a PDB to be plugged into a 12c Database Vault-enabled database. In addition, you must manually install Oracle Database Vault (and Oracle Label Security) in a PDB if this PDB does not have these products when the PDB has been plugged into a CDB where Database Vault and Label Security are installed.
  1. As user who has been granted the SYSDBA administrative privilege, log in to the PDB in which you want to install Oracle Database Vault. 
    sqlplus sec_admin@pdb_name as sysdba
Enter password: password

    Alternatively, log in to the CDB root as a user with DV_OWNER or DV_ADMIN role, and then check that that all of the PDBs are open and if Oracle Database Vault is in all of the associated PDBs. You can check if the PDB is open by connecting to it and then querying the OPEN_MODE column from the V$DATABASE view. To find if there is an Oracle Database Vault installation on the CDB, execute this query: 

    SELECT * FROM CDB_DV_STATUS;
  2. If necessary, check if Oracle Database Vault and Oracle Label Security are already installed on this PDB.
    If the DVSYS and DVF accounts (for Database Vault) and the LBACSYS account (for Label Security) exist, then Database Vault and Label Security exist on the PDB. 
    SELECT USERNAME FROM DBA_USERS WHERE USERNAME IN ('DVSYS', 'DVF', 'LBACSYS');
  3. If neither Database Vault nor Label Security have been installed, then install Oracle Label Security by executing the catols.sql script.
    @$ORACLE_HOME/rdbms/admin/catols.sql

    Oracle Label Security must be installed before you can install Oracle Database Vault.

  4. Install Oracle Database Vault by executing the catmac.sql script.
    @$ORACLE_HOME/rdbms/admin/catmac.sql
  5. At the Enter value for 1 prompt, enter SYSTEM as the tablespace to install DVSYS.
  6. At the Enter value for 2 prompt, enter the temporary tablespace for the PDB.
After the installation is complete, you can configure and enable Oracle Database Vault in the PDB. If Database Vault is not configured and enabled in the CDB already, then you must close the PDB before you can configure and enable Database Vault in the CDB root. Database Vault must be configured and enabled in CDB root before it can beconfigured and enabled in the PDB. After Database Vault is configured and enabled in the CDB root and the database has been restarted, then you can open the PDB and configure and enable Database Vault.

3.3 Verifying That Database Vault Is Configured and Enabled

The DBA_DV_STATUS, CDB_DV_STATUS, and DBA_OLS_STATUS data dictionary views verify if Oracle Database is configured and enabled.

In addition to Oracle Database Vault administrators, the Oracle Database SYS user and users who have been granted the DBA role can query these views.

  • For Database Vault:

    • If you want to find the Database Vault status for the root only or an individual PDB, then query DBA_DV_STATUS. For example: 

      SELECT * FROM DBA_DV_STATUS;

      Output similar to the following appears:

      NAME                 STATUS
-------------------- -----------
DV_APP_PROTECTION    NOT CONFIGURED
DV_CONFIGURE_STATUS  TRUE
DV_ENABLE_STATUS     TRUE

      DV_APP_PROTECTION refers to operations control, which automatically restricts common users from accessing PDB local data in autonomous, regular Cloud, or on-premises environments.

    • If you want to find the Database Vault status of all PDBs in the multitenant environment, then as a common user with administrative privileges, query CDB_DV_STATUS, which provides the addition of a container ID (CON_ID) field.

  • For Oracle Label Security, query the DBA_OLS_STATUS data dictionary view.

3.5 Quick Start Tutorial: Securing a Schema from DBA Access

This tutorial shows how to create a realm around the HR schema.

Parent topic: Getting Started with Oracle Database Vault

3.5.1 About This Tutorial

In this tutorial, you create a realm around for the HR sample database schema by using the Oracle Database Vault PL/SQL packages.

In the HR schema, the EMPLOYEES table has information such as salaries that should be hidden from most employees in the company, including those with administrative access. To accomplish this, you add the HR schema to the secured objects of the protection zone, which in Oracle Database Vault is called a realm, inside the database. Then you grant limited authorizations to this realm. Afterward, you test the realm to make sure it has been properly secured.

Parent topic: Quick Start Tutorial: Securing a Schema from DBA Access

3.5.2 Step 1: Log On as SYSTEM to Access the HR Schema

You must enable the HR schema for this tutorial.

Before you begin this tutorial, ensure that the HR sample schema is installed.
  1. Log in to a PDB as a user who has been granted the DBA role, and then access the HR schema.

    For example:

    sqlplus system@pdb_name
Enter password: password

    To find the available PDBs, query the PDB_NAME column of the DBA_PDBS data dictionary view. To check the current container, run the show con_name command.

  2. Query the HR.EMPLOYEES table as follows. 
    SELECT FIRST_NAME, LAST_NAME, SALARY FROM HR.EMPLOYEES WHERE ROWNUM < 10;

    Output similar to the following appears:

    FIRST_NAME           LAST_NAME                     SALARY
-------------------- ------------------------- ----------
Steven               King                           24000
Neena                Kochhar                        17000
Lex                  De Haan                        17000
Alexander            Hunold                          9000
Bruce                Ernst                           6000
David                Austin                          4800
Valli                Pataballa                       4800
Diana                Lorentz                         4200
Nancy                Greenberg                      12008

9 rows selected.
  3. If the HR schema is locked and expired, log in to the database instance as the DV_ACCTMGR user and unlock and unexpire the account. For example: 
    sqlplus accts_admin_ace@pdb_name
Enter password: password

ALTER USER HR ACCOUNT UNLOCK IDENTIFIED BY password

    Replace password with a password that meets the password complexity requirements of the user's profile.

    As you can see, SYSTEM has access to the salary information in the EMPLOYEES table of the HR schema. This is because SYSTEM is automatically granted the DBA role, which includes the SELECT ANY TABLE system privilege.

  4. Do not exit SQL*Plus.

3.5.3 Step 2: Create a Realm

Realms can protect one or more schemas, individual schema objects, and database roles.

After you create a realm, you can create security restrictions that apply to the schemas and their schema objects within the realm. You will need to create a realm for the HR schema.
  1. Connect to a PDB as a user who has been granted the DV_OWNER role.
    For example: 
    CONNECT c##sec_admin_owen@pdb_name
Enter password: password
  2. Create the HR App realm around the HR.EMPLOYEES table.
    1. Create the HR Apps realm itself. 
      BEGIN
 DBMS_MACADM.CREATE_REALM(
  realm_name    => 'HR Apps', 
  description   => 'Realm to protect the HR schema', 
  enabled       => DBMS_MACUTL.G_YES, 
  audit_options => DBMS_MACUTL.G_REALM_AUDIT_OFF,
  realm_type    => 0);
END; 
/
    2. Add the HR.EMPLOYEES table to this realm. 
      BEGIN
 DBMS_MACADM.ADD_OBJECT_TO_REALM(
  realm_name   => 'HR Apps', 
  object_owner => 'HR', 
  object_name  => 'EMPLOYEES', 
  object_type  => 'TABLE'); 
END;
/

At this stage, you have created the realm but you have not assigned any authorizations to it. You will take care of that later on in this tutorial.

3.5.4 Step 3: Create the SEBASTIAN User Account

At this stage, there are no database accounts or roles authorized to access or otherwise manipulate the database objects the realm will protect.

So, the next step is to authorize database accounts or database roles so that they can have access to the schemas within the realm. You will create the SEBASTIAN user account.

  1. In SQL*Plus, connect to the PDB as the Database Vault Account Manager, who has the DV_ACCTMGR role, and create the local user SEBASTIAN.

    For example:

    CONNECT accts_admin_ace@pdb_name
Enter password: password

GRANT CREATE SESSION TO SEBASTIAN IDENTIFIED BY password;

    Replace password with a password that meets the password complexity requirements of the user's profile.

  2. Connect as SYS with the SYSDBA privilege, and then grant SEBASTIAN the following additional privilege. 
    CONNECT SYS@pdb_name AS SYSDBA
Enter password: password

GRANT READ ANY TABLE TO SEBASTIAN;
  3. Do not exit SQL*Plus.

3.5.5 Step 4: Have User SEBASTIAN Test the Realm

At this stage, user SEBASTIAN can test the realm by trying to query the HR.EMPLOYEES table.

  1. Connect as user SEBASTIAN.
    CONNECT sebastian@pdb_name
Enter password: password
  2. Query the HR.EMPLOYEES table. 
    SELECT COUNT(*) FROM HR.EMPLOYEES;

    The following output should appear:

    ERROR at line 1:
ORA-01031: insufficient privileges
Even though user SEBASTIAN has the READ ANY TABLE system privilege, he cannot query the HR.EMPLOYEES table, because the HR Apps realm takes precedence over the READ ANY TABLE system privilege.

Parent topic: Quick Start Tutorial: Securing a Schema from DBA Access

3.5.6 Step 5: Create an Authorization for the Realm

Next, user SEBASTIAN must be granted authorization to the HR Apps realm, so that he can access the HR.EMPLOYEES table.

  1. Connect to the PDB as a user who has been granted the DV_OWNER role.
    For example: 
    c##sec_admin_owen@pdb_name
Enter passwod: password
  2. Create an authorization for the HR Apps realm.

    This authorization allows SEBASTIAN to use the READ ANY TABLE system privilege on the HR.EMPLOYEES table that is protected by this realm. 

    BEGIN
 DBMS_MACADM.ADD_AUTH_TO_REALM(
  realm_name  => 'HR Apps', 
  grantee     => 'SEBASTIAN'); 
END;
/

3.5.7 Step 6: Test the Realm

To test the realm, you must try to access the EMPLOYEES table as a user other than HR.

(This tutorial does not cover the ability to prevent HR from accessing its own objects.)

The SYSTEM account normally has access to all objects in the HR schema because it has the SELECT ANY TABLE privilege, but now that you have safeguarded the EMPLOYEES table with Oracle Database Vault, this is no longer the case.

  1. In SQL*Plus, connect to the PDB as SYSTEM. 

    CONNECT SYSTEM@pdb_name
Enter password: password

  2. Try querying any of the rows in the EMPLOYEES table again.

    For example:

    SELECT FIRST_NAME, LAST_NAME, SALARY FROM HR.EMPLOYEES WHERE ROWNUM <10;

    The following output should appear:

    Error at line 1:
ORA-01031: insufficient privileges

    SYSTEM no longer has access to the EMPLOYEES table. (In fact, even user SYS does not have any access to this table.) However, user SEBASTIAN does have access to this information because SEBASTIAN is an authorized participant in the HR Apps realm.

  3. Connect as user SEBASTIAN. 

    CONNECT sebastian@pdb_name
Enter password: password

  4. Perform the following query:

    SELECT FIRST_NAME, LAST_NAME, SALARY FROM HR.EMPLOYEES WHERE ROWNUM <10;

    Output similar to the following appears:

    FIRST_NAME           LAST_NAME                     SALARY
-------------------- ------------------------- ----------
Steven               King                           24000
Neena                Kochhar                        17000
Lex                  De Haan                        17000
Alexander            Hunold                          9000
Bruce                Ernst                           6000
David                Austin                          4800
Valli                Pataballa                       4800
Diana                Lorentz                         4200
Nancy                Greenberg                      12008

9 rows selected.

3.5.8 Step 8: Remove the Components for This Tutorial

You can remove the components that you created for this tutorial if you no longer need them.

  1. Drop user SEBASTIAN.

    In SQL*Plus, log in to the PDB on as the Oracle Database Vault account manager (for example, accts_admin_ace) and then drop SEBASTIAN as follows: 

    sqlplus accts_admin_ace@pdb_name
Enter password: password

DROP USER SEBASTIAN;
  2. Delete the HR Apps realm.
    1. Connect to the PDB as a user who has been granted the DV_OWNER role.

      For example:

      c##sec_admin_owen@pdb_name
Enter password: password
    2. Execute the following statement to drop the HR Apps realm and its authorizations: 
      EXEC DBMS_MACADM.DELETE_REALM_CASCADE('HR Apps');
  3. If necessary, in SQL*Plus, lock and expire the HR account.
    1. Connect as a user who has the DV_ACCTMGR role (for example, user accts_admin_ace).
    2. Execute the following ALTER USER statement:
      ALTER USER HR ACCOUNT LOCK PASSWORD EXPIRE;
