Question 720
During a follow-up assurance engagement at a telecommunications provider, the IS auditor learns that privileged service identities stay enabled after the owning application is decommissioned. The affected operation supports customer provisioning and billing. Service availability and accurate customer billing depend on the process. What outcome would provide the STRONGEST evidence that the identified gap is resolved?
Explanation
Correct Answer
Correct. Sampled access removals, conflict checks and individually attributed privileged logs prove least privilege and separation. This is stronger than a manager's verbal assurance because it can be checked against the observed issue that privileged service identities stay enabled after the owning application is decommissioned. The reviewer must verify the remediation period and scope.
Incorrect Answers
Not the strongest closure evidence for this case. Acceptance here depends on observing audit independence and objective reviewer judgment, not only that test.
Not the strongest closure evidence for this case. It does not establish the requested audit independence and objective reviewer judgment outcome.
Not the strongest closure evidence for this case. That result could pass without demonstrating audit independence and objective reviewer judgment.
