22 Oracle Database Vault Policy APIs

You can use the DBMS_MACADM PL/SQL package to manage Oracle Database Vault policies.

Only users who have been granted the DV_OWNER or DV_ADMIN role can use these procedures.

ADD_CMD_RULE_TO_POLICY Procedure

The ADD_COMMAND_RULE_TO_POLICY procedure enables you to add an existing command rule to an Oracle Database Vault policy.

You can add a command rule to a policy when the command rule is in any state. For example, you can add a disabled command rule to an enabled policy. In this case, the disabled command rule will automatically become enabled when it is added to the policy. A command rules can be added to only one policy. In other words, you cannot assign the same command rule to multiple policies.

Syntax

DBMS_MACADM.ADD_CMD_RULE_TO_POLICY(
 policy_name    IN VARCHAR2,
 command        IN VARCHAR2,
 object_owner   IN VARCHAR2,
 object_name    IN VARCHAR2, 
 clause_name    IN VARCHAR2 DEFAULT,
 parameter_name IN VARCHAR2 DEFAULT,
 event_name     IN VARCHAR2 DEFAULT,
 component_name IN VARCHAR2 DEFAULT,
 action_name    IN VARCHAR2 DEFAULT,
 scope          IN NUMBER DEFAULT);

scope

For a multitenant environment, determines how to execute this procedure. The default is local. Options are as follows:

  • DBMS_MACUTL.G_SCOPE_LOCAL (or 1) if the command rule is local in the current PDB

The following example shows how to add a common command rule to a Database Vault policy. This command rule is in the application root of a multitenant environment, so the user running this procedure must be in the application root or the CDB root. Any rules or rule sets that are associated with this command rule must be common.

  policy_name    => 'HR_DV_Policy',
  command        => 'ALTER SESSION',
  object_owner   => '%',
  object_name    => '%',
  clause_name    => 'PARALLEL DDL',

ADD_OWNER_TO_POLICY Procedure

The ADD_OWNER_TO_POLICY procedure enables you to add an existing database user to an Oracle Database Vault policy as an owner.

When you add an owner to an enabled policy, the change takes place immediately. There is no limit to the number of users that you add to the policy.

Syntax

DBMS_MACADM.ADD_OWNER_TO_POLICY(
  policy_name   IN VARCHAR2,
  owner_name    IN VARCHAR2);

Parameters

Table 22-2 ADD_OWNER_TO_POLICY Parameters

Parameter Description

policy_name

Policy name. To find existing Database Vault policies in the current database instance, query the DBA_DV_POLICY view, described in DBA_DV_POLICY View.

owner_name

User name. To find existing database users (not roles) in the current instance, query the DBA_USERS view, described in Oracle Database Reference. To find existing policy owners, query the DBA_DV_POLICY_OWNER view, described in DBA_DV_POLICY_OWNER View.

Example

BEGIN
 DBMS_MACADM.ADD_OWNER_TO_POLICY(
  policy_name    => 'HR_DV_Policy',
  owner_name     => 'PSMITH');
END;

Syntax

DBMS_MACADM.ADD_REALM_TO_POLICY(
  policy_name   IN VARCHAR2,
  realm_name    IN VARCHAR2);

Parameters

Table 22-3 ADD_REALM_TO_POLICY Parameters

Parameter Description

policy_name

Policy name. To find existing Database Vault policies in the current database instance, query the DBA_DV_POLICY view, described in DBA_DV_POLICY View.

realm_name

Realm name. To find existing Database Vault realms in the current database instance, query the DV_REALM view, described in DVSYS.DV$REALM View.

CREATE_POLICY Procedure

The CREATE_POLICY procedure enables you to create an Oracle Database Vault policy.

After you create the policy, you must add at least one realm and one command rule to the policy. Optionally, you can set these realms and command rules to be enforced individually or use the enforcement that the policy uses.

An owner for the policy is not required, but if you do not assign an owner to the policy, a user who has been granted the DV_OWNER or DV_ADMIN role must administer the policy.

After you create the policy, use the following procedures to complete the policy definition:

  • ADD_REALM_TO_POLICY adds realms to the policy.

  • ADD_CMD_RULE_TO_POLICY adds command rules to the policy.

  • ADD_OWNER_TO_POLICY enables the specified database users to manage the policy.

Syntax

DBMS_MACADM.CREATE_POLICY(
 policy_name  IN VARCHAR2,
 description  IN VARCHAR2 DEFAULT,
 policy_state IN NUMBER,
 pl_sql_stack IN BOOLEAN DEFAULT);

Parameters

Table 22-4 CREATE_POLICY Parameters

Parameter Description

policy_name

Policy name, up to 128 characters in mixed case

To find existing policies in the current database instance, query the DBA_DV_POLICY view, described in DBA_DV_POLICY View.

description

Description of the purpose of the policy, up to 4000 characters in mixed-case.

policy_state

Specifies how the policy is enabled. Possible values are:

  • DBMS_MACADM.G_ENABLED (1), which enables the policy after you create it

  • DBMS_MACADM.G_DISABLED (0), which disables the policy after you create it

  • DBMS_MACADM.G_SIMULATION (2), which sets the policy to simulation mode. In simulation mode, any violations to realms or command rules used in the policy are logged in a designated log table with sufficient information to describe the error, such as the user name or SQL statement used.

  • DBMS_MACADM.G_PARTIAL (3), which sets the policy to partial mode. In partial mode, the enforcement state of realms or command rules associated with the policy can be changed individually.

See About Simulation Mode for more information about simulation mode

pl_sql_stack

When simulation mode is enabled, specifies whether to record the PL/SQL stack for failed operations. Enter TRUE to record the PL/SQL stack, FALSE to not record.

Example

The following example creates a policy that uses the partial state and enables the capture of the PL/SQL stack. Later on, when a realm or a command rule is added to this policy, their enforcement state will be able to be changed individually. 

BEGIN
 DBMS_MACADM.CREATE_POLICY(
  policy_name  => 'HR Database Vault Policy',
  description  => 'Policy to protect the HR schema',
  policy_state => DBMS_MACADM.G_ENABLED,
  pl_sql_stack => TRUE);
END;

DELETE_CMD_RULE_FROM_POLICY Procedure

The DELETE_CMD_RULE_FROM_POLICY procedure enables you to remove an existing command rule from an Oracle Database Vault policy.

You can remove command rules from a policy anytime regardless of the state of the policy. When a command rule is removed from a policy, the state of command rule remains the same. That is, if the policy is enabled, and a command rule is removed from the policy, then the command rule will be still enabled after you have removed it from the policy.

Syntax

DBMS_MACADM.DELETE_CMD_RULE_FROM_POLICY(
 policy_name    IN VARCHAR2,
 command        IN VARCHAR2,
 object_owner   IN VARCHAR2,
 object_name    IN VARCHAR2, 
 clause_name    IN VARCHAR2 DEFAULT,
 parameter_name IN VARCHAR2 DEFAULT,
 event_name     IN VARCHAR2 DEFAULT,
