Question 590
After addressing this situation: An energy company ranks every cyber event as critical because no assessment thresholds were approved. Which observed result provides the strongest relevant assurance?
Explanation
Correct Answer
Comparable scenarios receive consistent ratings and exceptions have documented accountable approval. This is the relevant test result for the scenario in which an energy company ranks every cyber event as critical because no assessment thresholds were approved. It verifies the action to establish documented criteria for consistent risk assessment, evaluation and acceptance. The corresponding operating design is to agree likelihood and consequence scales, acceptance limits and approval responsibilities before assessment. The result should rule out the error of letting each project manager invent new risk acceptance criteria after seeing the results.
Incorrect Answers
Reviews can find both the current authorized instructions and authentic dated performance records. This may be a useful result for documented information and record distinction in another case, such as when a technology team stores an unsigned policy draft where auditors expect evidence that access reviews occurred. It does not establish effectiveness of the controls necessary for the described problem. The relevant evidence is that comparable scenarios receive consistent ratings and exceptions have documented accountable approval. Case: An energy company ranks every cyber event as critical because no assessment thresholds were approved.
Recovery evidence demonstrates clean restoration and confirmation of the repaired service. This may be a useful result for corrective control classification in another case, such as when a ransomware exercise finds the backup service cannot restore corrupted application data. It does not establish effectiveness of the controls necessary for the described problem. The relevant evidence is that comparable scenarios receive consistent ratings and exceptions have documented accountable approval. Case: An energy company ranks every cyber event as critical because no assessment thresholds were approved.
Scope review shows critical information flows and interfaces are addressed and exclusions explained. This may be a useful result for risk-driven scope and context in another case, such as when a subsidiary narrows its ISMS boundary to one office although data processing extends to shared cloud services. It does not establish effectiveness of the controls necessary for the described problem. The relevant evidence is that comparable scenarios receive consistent ratings and exceptions have documented accountable approval. Case: An energy company ranks every cyber event as critical because no assessment thresholds were approved.
