SQL Server must isolate security functions from nonsecurity functions.
Medium Severity
<VulnDiscussion>An isolation boundary provides access control and protects the integrity of the hardware, software, and firmware that perform security functions. Security functions are defined as "the hardware, software, and/or firmware of the information system responsible for enforcing the system security policy and supporting the isolation of code and data on which the protection is based". Developers and implementers can increase the assurance in security functions by employing well-defined security policy models; structured, disciplined, and rigorous hardware and software development techniques; and sound system/security engineering principles. Database Management Systems typically separate security functionality from nonsecurity functionality via separate databases or schemas. SQL Server's [master] database and [sys] schema are examples of this. Further granularity of access protection is provided by assigning logins and users to appropriate server roles and database roles Database objects or code implementing security functionality should not be commingled with objects or code implementing application logic. When security and nonsecurity functionality is commingled, users who have access to nonsecurity functionality may be able to access security functionality.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
