O19C-00-001800 - Oracle Database must provide audit record generation capability for organization-defined auditable events within the database.

Information

Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.

Audit records can be generated from various components within the database management system (DBMS) (e.g., process, module). Certain specific application functionalities may be audited as well. The list of audited events is the set of events for which audits are to be generated. This set of events is typically a subset of the list of all events for which the system is capable of generating audit records.

DOD has defined the list of events for which the DBMS will provide an audit record generation capability as the following:

(i) Successful and unsuccessful attempts to access, modify, or delete privileges, security objects, security levels, or categories of information (e.g., classification levels);

(ii) Access actions, such as successful and unsuccessful login attempts, privileged activities, or other system-level access, starting and ending time for user access to the system, concurrent logins from different workstations, successful and unsuccessful accesses to objects, all program initiations, and all direct access to the information system; and

(iii) All account creation, modification, disabling, and termination actions.

Organizations may define additional events requiring continuous or ad hoc auditing.

Solution

Configure the DBMS's auditing to audit organization-defined auditable events. If preferred, use a third-party tool. The tool must provide the minimum capability to audit the required events.

If using a third-party product, proceed in accordance with the product documentation. If using Oracle's capabilities, proceed as follows.

If Standard Auditing is used:
Use this process to ensure auditable events are captured:

ALTER SYSTEM SET AUDIT_TRAIL=<audit trail type> SCOPE=SPFILE;
Audit trail type can be 'OS', 'DB', 'DB,EXTENDED', 'XML' or 'XML,EXTENDED'.

After executing this statement, it may be necessary to shut down and restart the Oracle database.

If the site-specific audit requirements are not covered by the default audit options, deploy and configure Fine-Grained Auditing. For details, refer to Oracle documentation at the locations below.

If Unified Auditing is used:
Use this process to ensure auditable events are captured:
Link the oracle binary with uniaud_on, and then restart the database. Oracle Database Upgrade Guide describes how to enable unified auditing.
