Question 430
A team is trying to correct the issue that follows: A data processor has documented a high risk but nobody decides whether to mitigate, avoid, share or retain it. Which practice would recreate the principal weakness?
Explanation
Correct Answer
Equating a technically installed control with formal approval to accept the resulting residual risk. This is the most directly harmful practice for the specific issue where a data processor has documented a high risk but nobody decides whether to mitigate, avoid, share or retain it. It could leave the organization facing unapproved residual risks surviving despite an apparent remediation project. Instead, the implementer should require justified risk treatment decisions and explicit ownership of residual exposure. A suitable check is that the risk owner approves the remaining exposure after treatment evidence is reviewed.
Incorrect Answers
Assuming the Statement of Applicability is just a list of purchased products. This would be a concern in a different topic, such as when a financial group publishes a list of security tools but no statement explaining applicable Annex A controls. It is not the defining mistaken approach for the problem described. The error to avoid in this case is equating a technically installed control with formal approval to accept the resulting residual risk. The linked exposure is unapproved residual risks surviving despite an apparent remediation project. Case: A data processor has documented a high risk but nobody decides whether to mitigate, avoid, share or retain it.
Relying on a signed policy while operational workflows ignore its requirements. This would be a concern in a different topic, such as when a payment firm writes a risk treatment plan but no one incorporates it into daily change and access processes. It is not the defining mistaken approach for the problem described. The error to avoid in this case is equating a technically installed control with formal approval to accept the resulting residual risk. The linked exposure is unapproved residual risks surviving despite an apparent remediation project. Case: A data processor has documented a high risk but nobody decides whether to mitigate, avoid, share or retain it.
Treating a password checklist as a complete organizational security policy. This would be a concern in a different topic, such as when a public health agency relies on a decades-old informal statement that never reaches suppliers or employees. It is not the defining mistaken approach for the problem described. The error to avoid in this case is equating a technically installed control with formal approval to accept the resulting residual risk. The linked exposure is unapproved residual risks surviving despite an apparent remediation project. Case: A data processor has documented a high risk but nobody decides whether to mitigate, avoid, share or retain it.
