SQL Server must generate Trace or Audit records when unsuccessful attempts to add privileges/permissions occur.
Medium Severity
<VulnDiscussion>Failed attempts to change the permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized attempts to elevate or restrict privileges could go undetected. In SQL Server, adding permissions is typically done via the GRANT command, or, in the negative, DENY; or with the ALTER SERVER ROLE . . . ADD MEMBER . . ., and/or ALTER ROLE . . . ADD MEMBER . . . commands. Native security functionality may be supplemented with application-specific tables and logic, in which case the following actions on these tables and procedures/triggers/functions are also relevant: INSERT UPDATE EXECUTE 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>
