User-managed resources must be created in dedicated namespaces.
An XCCDF Rule
Description
<VulnDiscussion>Creating namespaces for user-managed resources is important when implementing Role-Based Access Controls (RBAC). RBAC allows for the authorization of users and helps support proper API server permissions separation and network micro segmentation. If user-managed resources are placed within the default namespaces, it becomes impossible to implement policies for RBAC permission, service account usage, network policies, and more.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
