Question 160
In the following case: A payroll team finds that approved salary entries are silently altered during a nightly import. Which approach should the ISMS lead most specifically avoid?
Explanation
Correct Answer
Using encryption alone as evidence that records cannot be altered by an authorized but careless operator. This is the most directly harmful practice for the specific issue where a payroll team finds that approved salary entries are silently altered during a nightly import. It could leave the organization facing undetected alteration of critical data leading to wrong financial or safety decisions. Instead, the implementer should establish controlled changes and integrity verification for the affected business records. A suitable check is that reconciliation reveals approved changes and detects unauthorized or malformed data modifications.
Incorrect Answers

Classifying data solely by file extension without considering its business sensitivity. This would be a concern in a different topic, such as when an NGO assigns a single handling label to public reports and restricted beneficiary identities.

Assuming a monitoring alarm prevents the suspicious action rather than identifying it.

It is not the defining mistaken approach for the problem described. The error to avoid in this case is using encryption alone as evidence that records cannot be altered by an authorized but careless operator. The linked exposure is undetected alteration of critical data leading to wrong financial or safety decisions.
