Kubernetes must have a pod security policy set.
High Severity
<VulnDiscussion>Enabling the admissions webhook allows for Kubernetes to apply policies against objects that are to be created, read, updated, or deleted. By applying a pod security policy, control can be given to not allow images to be instantiated that run as the root user. If pods run as the root user, the pod then has root privileges to the host system and all the resources it has. An attacker can use this to attack the Kubernetes cluster. By implementing a policy that does not allow root or privileged pods, the pod users are limited in what the pod can do and access.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
