SQL Server must generate audit records for the DoD-selected list of auditable events.
Overview

| Description |
|---|
| Audit records can be generated from various components within the information system, such as network interfaces, hard disks, modems, etc. From an application perspective, 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 (i.e., auditable events, time stamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, file names involved, and access control or flow control rules invoked). Organizations may define the organizational personnel accountable for determining which application components shall provide auditable events. Auditing provides accountability for changes made to the SQL Server configuration or its objects and data. It provides a means to discover suspicious activity and unauthorized changes. Without auditing, a compromise may go undetected and without a means to determine accountability. |

| Check to see that all required events are being audited. From the query prompt: SELECT DISTINCT traceid FROM ::FN_TRACE_GETINFO('0') All currently defined traces for the SQL server instance will be listed. If no traces are returned, this is a finding. Determine the trace being used for the auditing requirement. Replace # with a traceid being used for the auditing requirements. From the query prompt: SELECT DISTINCT(eventid) FROM ::FN_TRACE_GETEVENTINFO('#') The required eventids 14, 15, 18, 20, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 115, 116, 117, 118, 128, 129, 130, 131, 132, 133, 134, 135, 152, 153, 170, 171, 172, 173, 175, 176, 177 and 178 should be listed. If any of the audit events or eventids required above are not listed, this is finding. |
