Question 10
Consider this organizational security issue: A hospital deploys access controls but never reevaluates the remaining patient-data risk. What is the most appropriate primary action for the ISMS implementer?
Explanation
Correct Answer
Ensure the accountable risk owner reviews and approves residual exposure after treatment. The specific evidence is that a hospital deploys access controls but never reevaluates the remaining patient-data risk. In practical terms, the team should require documented risk reassessment and acceptance against approved criteria. Effectiveness can then be demonstrated when approved residual-risk records identify the risk owner, evidence and validity conditions. Without this intervention, the main exposure is unapproved material residual risk after implementation.
Incorrect Answers
Plan control implementation with accountable ownership, resources, timing and verification. This is a plausible intervention for a different ISMS issue, such as when a chemical plant assigns a final deadline to every safeguard without identifying technology dependencies. It does not directly remedy residual risk ownership in the described case. Here the primary action is to ensure the accountable risk owner reviews and approves residual exposure after treatment. Case: A hospital deploys access controls but never reevaluates the remaining patient-data risk.
Estimate and secure people, budget, capabilities and tools needed to deliver the ISMS. This is a plausible intervention for a different ISMS issue, such as when a new financial services provider sets controls requiring skills no current staff possess. It does not directly remedy residual risk ownership in the described case. Here the primary action is to ensure the accountable risk owner reviews and approves residual exposure after treatment. Case: A hospital deploys access controls but never reevaluates the remaining patient-data risk.
Create a phased ISMS implementation plan with dependencies, owners and milestones. This is a plausible intervention for a different ISMS issue, such as when a public agency initiates risk assessment, policy rollout and audit preparation without sequencing dependent work. It does not directly remedy residual risk ownership in the described case. Here the primary action is to ensure the accountable risk owner reviews and approves residual exposure after treatment. Case: A hospital deploys access controls but never reevaluates the remaining patient-data risk.
