PECB Exam ISO-IEC-27005-Risk-Manager Topic 1 Question 16 Discussion

ISO/IEC 27005 advises that even after risks have been treated, any residual risks should be continuously monitored and reviewed. This is necessary to ensure that they remain within acceptable levels and that any changes in the internal or external environment do not escalate the risk beyond acceptable thresholds. Monitoring also ensures that the effectiveness of the controls remains adequate over time. Option A is incorrect because all risks, including those meeting the risk acceptance criteria, should be monitored. Option B is incorrect because monitoring is necessary regardless of the perceived severity if it occurs, to detect changes early.
