正解:B
The audit team identified control risk, making option B the correct answer. Control risk refers to the risk that an organization's internal controls will fail to prevent, detect, or correct a material issue or security weakness.
In the scenario, the audit team identified a lack of oversight in the firewall configuration review process, where changes were implemented without proper approval. This clearly indicates a weakness in internal control mechanisms.
Firewall configuration management is a key security control area. The absence of proper approval and review processes increases the likelihood that unauthorized or insecure changes could be introduced, exposing the organization to vulnerabilities. This does not represent inherent risk, which relates to risks arising naturally from the nature of the business or environment. Instead, it highlights a failure in the design or operation of controls intended to manage those risks.
Option C is incorrect because detection risk relates to the possibility that auditors fail to identify existing issues during the audit. In this case, the auditors successfully identified the weakness, so detection risk is not applicable. Option A is incorrect because the issue does not stem from the inherent nature of CyberShielding' s operations but from inadequate control oversight.
Therefore, the identified issue is best classified as control risk, as it reflects deficiencies in internal control effectiveness within the ISMS.
