Access to database files must be limited to relevant processes and to authorized, administrative users.
An XCCDF Rule
Description
<VulnDiscussion>Applications, including DBMSs, must prevent unauthorized and unintended information transfer via shared system resources. Permitting only DBMS processes and authorized, administrative users to have access to the files where the database resides helps ensure that those files are not shared inappropriately and are not open to backdoor access and manipulation. As a general rule, distributed files and resources should follow the principal of least privilege, which requires that users, processes, programs, and other system components only have access to information and resources required for their legitimate purpose.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
