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.
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. If Standard Auditing is used: To see if Oracle is configured to capture audit data, enter the following SQL*Plus command: SHOW PARAMETER AUDIT_TRAIL or the following SQL query: SELECT * FROM SYS.V$PARAMETER WHERE NAME = 'audit_trail'; If Oracle returns the value 'NONE', this is a finding. To confirm that Oracle audit is capturing sufficient information to establish the source of events, perform a successful auditable action and an auditable action that results in an SQL error, and then view the results in the SYS.AUD$ table or the audit file, whichever is in use. If correct values for User ID, User Host, and Terminal are not returned when applicable, this is a finding. If Unified Auditing is used: To see if Oracle is configured to capture audit data, enter the following SQL*Plus command: SELECT * FROM V$OPTION WHERE PARAMETER = 'Unified Auditing'; If Oracle returns the value "TRUE", this is not a finding. To confirm that Oracle audit is capturing sufficient information to establish the source of events, perform a successful auditable action and an auditable action that results in an SQL error, and then view the results in the SYS.UNIFIED_AUDIT_TRAIL view. If correct values for User ID, User Host, and Terminal are not returned when applicable, this is a finding.
Configure the DBMS's auditing to audit standard and organization-defined auditable events, the audit record to include the source of the event. 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=
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.
