O121-C2-007400 - The DBMS must produce audit records containing sufficient information to establish what type of events occurred.
Information
Information system auditing capability is critical for accurate forensic analysis. Audit record content that may be necessary to satisfy the requirement of this control includes: timestamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, file names involved, and access control or flow control rules invoked.Database software is capable of a range of actions on data stored within the database. It is important, for accurate forensic analysis, to know exactly what actions were performed. This requires specific information regarding the event type an audit record is referring to. If event type information is not recorded and stored with the audit record, the record itself is of very limited use.
Solution
Configure the DBMS's auditing to audit standard and organization-defined auditable events, the audit record to include what type of event occurred. If preferred, use a third-party or custom tool.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 Unified Auditing is used:
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.
