| If there are no locally-defined security tables or procedures, this is not a finding. |
If neither SQL Server Audit nor SQL Server Trace is in use for audit purposes, this is a finding.
If SQL Server Trace is in use for audit purposes, verify that all required events are being audited. From the query prompt:
SELECT * FROM sys.traces;
All currently defined traces for the SQL server instance will be listed. If no traces are returned, this is a finding.
Determine the trace(s) being used for the auditing requirement.
In the following, replace # with a trace ID being used for the auditing requirements.
From the query prompt:
SELECT DISTINCT(eventid) FROM sys.fn_trace_geteventinfo(#);
The following required event IDs should all be among those listed; if not, this is a finding:
46 -- Object:Created
47 -- Object:Deleted
162 -- User error message
164 -- Object:Altered
If SQL Server Audit is in use, proceed as follows.
The basic SQL Server Audit configuration provided in the supplemental file Audit.sql uses the broad, server-level audit action group SCHEMA_OBJECT_CHANGE_GROUP for this purpose. SQL Server Audit's flexibility makes other techniques possible. If an alternative technique is in use and demonstrated effective, this is not a finding.
Determine the name(s) of the server audit specification(s) in use.
To look at audits and audit specifications, in Management Studio's object explorer, expand
>> Security >> Audits
>> Security >> Server Audit Specifications.
>> Databases >> >> Security >> Database Audit Specifications.
Alternatively, review the contents of the system views with "audit" in their names.
Run the following to verify that all CREATE, ALTER, and DROP actions on any locally-defined permissions tables, procedures and functions are being audited:
SELECT * FROM sys.server_audit_specification_details WHERE server_specification_id =
(SELECT server_specification_id FROM sys.server_audit_specifications WHERE [name] = '')
AND audit_action_name = 'SCHEMA_OBJECT_CHANGE_GROUP';
If no row is returned, this is a finding.
If the audited_result column is not "FAILURE" or "SUCCESS AND FAILURE", this is a finding.
