SQL Server must enforce approved authorizations for logical access to server-level system resources in accordance with applicable access control policies.
SQL Server must enforce approved authorizations for logical access to server-level system resources in accordance with applicable access control policies. An XCCDF Rule
SQL Server must enforce approved authorizations for logical access to server-level system resources in accordance with applicable access control policies.
Medium Severity
<VulnDiscussion>Authentication with a DoD-approved PKI certificate does not necessarily imply authorization to access the SQL Server instance and server-level resources. To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoD-approved PKIs, all DoD systems, including SQL Server instances, must be properly configured to implement access control policies.
Successful authentication must not automatically give an entity access to an asset or security boundary. Authorization procedures and controls must be implemented to ensure each authenticated entity also has a validated and current authorization. Authorization is the process of determining whether an entity, once authenticated, is permitted to access a specific asset. Information systems use access control policies and enforcement mechanisms to implement this requirement.
Access control policies include identity-based policies, role-based policies, and attribute-based policies. Access enforcement mechanisms include access control lists, access control matrices, and cryptography. These policies and mechanisms must be employed by the application to control access between users (or processes acting on behalf of users) and objects (e.g., devices, files, records, processes, programs, and domains) in the information system.
This requirement is applicable to access control enforcement applications, a category that includes SQL Server. If SQL Server is not configured to follow applicable policy when approving access, it may be in conflict with networks or other applications in the information system. This may result in users either gaining or being denied access inappropriately and in conflict with applicable policy.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
