SQL Server must generate Trace or Audit records when unsuccessful attempts to delete privileges/permissions occur.
Medium Severity
<VulnDiscussion>Changes in the permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized elevation or restriction of privileges could go undetected. Elevated privileges give users access to information and functionality that they should not have; restricted privileges wrongly deny access to authorized users. In SQL Server, deleting permissions is typically done via the REVOKE or DENY command; or with the ALTER SERVER ROLE . . . DROP MEMBER . . . and/or ALTER ROLE . . . DROP MEMBER . . . statements. To aid in diagnosis, it is necessary to keep track of failed attempts in addition to the successful ones. 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>
