The container platform runtime must maintain separate execution domains for each container by assigning each container a separate address space.
An XCCDF Rule
Description
<VulnDiscussion>Container namespace access is limited upon runtime execution. Each container is a distinct process so that communication between containers is performed in a manner controlled through security policies that limits the communication so one container cannot modify another container. Different groups of containers with different security needs should be deployed in separate namespaces as a first level of isolation. Namespaces are a key boundary for network policies, orchestrator access control restrictions, and other important security controls. Separating workloads into namespaces can help contain attacks and limit the impact of mistakes or destructive actions by authorized users.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Deploy a container platform runtime capable of maintaining a separate execution domain and namespace for each executing process. Create a namespace for each containers, defining them as logical groups.
