Question 670
At Elmwood Manufacturing, a team reports that it corrected the following problem affecting industrial analytics and business systems: A container security agent needs kernel-event visibility but introducing a new custom kernel module is operationally risky. Which observation BEST verifies that the correction actually worked?
Explanation
Correct Answer
A monitored syscall pattern is observed without loading an unreviewed kernel module. This is the decisive evidence for the original problem: A container security agent needs kernel-event visibility but introducing a new custom kernel module is operationally risky. It verifies that the intended corrective control—Evaluate supported eBPF instrumentation with appropriate privileges and verifier protections—works in the relevant environment; a completed change ticket alone would not prove the outcome at Elmwood Manufacturing.
Incorrect Answers
An unapproved service cannot call the protected container while permitted traffic works. This would be relevant evidence for a different failure: A container orchestrator leaves external ingress and internal service-to-service traffic unrestricted, usually addressed by Define ingress policies and network segmentation appropriate to application trust boundaries. It does not demonstrate that the current problem at Elmwood Manufacturing was resolved. The specific required evidence is: A monitored syscall pattern is observed without loading an unreviewed kernel module.
A container escape attempt cannot access protected host files and the app still functions. This would be relevant evidence for a different failure: A workload has root-level container privileges and can access sensitive host paths unnecessarily, usually addressed by Apply least-privilege container runtime security and restrict host mounts and capabilities. It does not demonstrate that the current problem at Elmwood Manufacturing was resolved. The specific required evidence is: A monitored syscall pattern is observed without loading an unreviewed kernel module.
An anomalous child process triggers a workload-linked security event. This would be relevant evidence for a different failure: A cloud-native workload has no runtime alert for unexpected process execution after deployment, usually addressed by Add supported runtime behavior monitoring and event correlation for containers or hosts. It does not demonstrate that the current problem at Elmwood Manufacturing was resolved. The specific required evidence is: A monitored syscall pattern is observed without loading an unreviewed kernel module.
