SQL Server must produce Trace or Audit records containing sufficient information to establish the identity of any user/subject associated with the event.
An XCCDF Rule
Description
<VulnDiscussion>Information system auditing capability is critical for accurate forensic analysis. Audit record content which may be necessary to satisfy the requirement of this control includes: 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. 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 who performed a given action. If user identification information is not recorded and stored with the audit record, the record itself is of very limited use. Use of SQL Server Audit is recommended. All features of SQL Server Audit are available in the Enterprise and Developer editions of SQL Server 2014. It is not available at the database level in other editions. For this or legacy reasons, the instance may be using SQL Server Trace for auditing, which remains an acceptable solution for the time being. Note, however, that Microsoft intends to remove most aspects of Trace at some point after SQL Server 2016.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Remediation - Manual Procedure
If Trace is in use for audit purposes, design and deploy a Trace that captures the NT User Name, NT Domain Name, Host Name, Login Name, DB User Name and Login SID (each where relevant) for all auditable events. The script provided in the supplemental file Trace.sql can be used to create a trace.
If SQL Server Audit is intended to be in use, design and deploy an Audit that captures all auditable events. The code provided in the supplemental file Audit.sql can be used as the basis for creating an Audit.
