Question 465

An IS auditor evaluates this situation: An auditor cannot decide whether to review a high-impact legacy billing interface because no recent incidents are recorded. Which audit principle MOST directly applies to this situation?

  1. Quality monitoring should reveal overdue high-risk actions and escalation effectiveness.
  2. Audit scope must be based on independent assessment of relevant risk rather than auditee preference.
  3. Absence of reported incidents is not proof of low inherent or residual risk.
  4. A nonrepresentative selection can lead to unsupported conclusions about the entire population.

Explanation

Correct Answer

C:

Absence of reported incidents is not proof of low inherent or residual risk. The corresponding audit procedure is: Collect business criticality, interface volume, control maturity, change history and incident reporting quality.
