Question 520
At the Zephyrhaven online learning platform, one Kubernetes service account can list all namespace secrets though it reads only one configuration item. Which setting or practice should be reviewed in future?
Explanation
Correct Answer
This control works beyond the initial remediation because it requires the team to review service account RBAC after workload migrations.
Incorrect Answers
Review admission-policy violations and image signatures routinely is not the primary recurring safeguard for this problem. The team should review service account RBAC after workload migrations. For the Zephyrhaven online learning platform, the direct corrective action is to grant minimal RBAC verbs and resource scopes and rotate exposed service credentials.
The suggested preventive check is: Update the cloud security baseline as service types change. Its technical scope concerns: Cloud adoption alone does not define a coherent threat-based control architecture. This question asks how to sustain control over: Broad Kubernetes API permissions let a compromised pod enumerate unrelated secrets. The more targeted safeguard is: Review service account RBAC after workload migrations.
Review PaaS eligibility whenever host customization requirements change. That safeguard would help prevent recurrence of: IaaS carries guest OS management responsibilities absent from a qualifying PaaS workload. The risk being reviewed here is instead: Broad Kubernetes API permissions let a compromised pod enumerate unrelated secrets. The matching ongoing control is: Review service account RBAC after workload migrations.
