Vulnerability discussion

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, but is not limited to: timestamps, source and destination IP addresses, user/process identifiers, event descriptions, application specific events, success/fail indications, file names involved, access control, or flow control rules invoked. Success and failure indicators ascertain the outcome of a particular event. As such, they also provide a means to measure the impact of an event and help authorized personnel to determine the appropriate response. Without knowing the outcome of audit events, it is very difficult to accurately recreate the series of events during forensic analysis.

Check content

Verify, using vendor and system documentation if necessary, that the DBMS is configured to use Oracle's auditing features, or that a third-party product or custom code is deployed and configured to satisfy this requirement. If a third-party product or custom code is used, compare its current configuration with the audit requirements. If any of the requirements is not covered by the configuration, this is a finding. The remainder of this Check is applicable specifically where Oracle auditing is in use. To see if Oracle is configured to capture audit data, enter the following SQLPlus command: SHOW PARAMETER AUDIT_TRAIL or the following SQL query: SELECT * FROM SYS.V$PARAMETER WHERE NAME = 'audit_trail'; If Oracle returns the value 'NONE', this is a finding. To confirm that Oracle audit is capturing sufficient information to establish outcomes, perform a successful auditable action and an auditable action that results in an SQL error, and then view the results in the SYS.AUD$ table or the audit file, whichever is in use. If no return code or other outcome information is returned for the auditable action just performed, this is a finding. If error is indicated for the successful action, this is a finding. If no error is indicated for the unsuccessful action, this is a finding.

Fix text

Configure the DBMS's auditing to audit standard and organization-defined auditable events, the audit record to include the outcome. 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. Use this query to ensure auditable events are captured: ALTER SYSTEM SET AUDIT_TRAIL= 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. For more information on the configuration of auditing, please refer to "Auditing Database Activity" in the Oracle Database 2 Day + Security Guide: http://docs.oracle.com/cd/E11882_01/server.112/e10575/tdpsg_auditing.htm and "Verifying Security Access with Auditing" in the Oracle Database Security Guide: http://docs.oracle.com/cd/E11882_01/network.112/e36292/auditing.htm#DBSEG006 and "27 DBMS_AUDIT_MGMT" in the Oracle Database PL/SQL Packages and Types Reference: http://docs.oracle.com/cd/E11882_01/appdev.112/e40758/d_audit_mgmt.htm

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
