Residual biometric characteristics, such as fingerprints left on a biometric capture device, may be reused by an attacker to gain unauthorized access. A brute force attack involves feeding the biometric capture device numerous different biometric samples. A cryptographic attack targets the algorithm or the encrypted data, in a mimic attack, the attacker reproduces characteristics similar to those of the enrolled user, such as forging a signature or imitating a voice.

This is because the follow-up of agreed corrective actions for reported audit issues should be done after the auditee has had enough time to implement the corrective actions and demonstrate their effectiveness and sustainability. The follow-up audit should not be too soon or too late, but based on a reasonable and realistic timeframe that allows for adequate testing and verification of the control operation12.
A). Progress updates indicate that the implementation of agreed actions is on track. is not the best answer, because progress updates are not sufficient to guide the follow-up audit timing. Progress updates are useful for monitoring and communicating the status and challenges of the corrective actions, but they do not provide conclusive evidence of the control operation. The follow-up audit should be based on actual results and outcomes, not on expectations or projections12.
C). Business management has completed the implementation of agreed actions on schedule. is not the best answer, because the completion of the implementation of agreed actions is not enough to guide the follow-up audit timing. The completion of the implementation only indicates that the auditee has taken the necessary steps to address the audit issues, but it does not guarantee that the corrective actions are effective and sustainable. The follow-up audit should be based on the evaluation and validation of the control operation, not on the completion of the control implementation12.
D). Regulators have announced a timeline for an inspection visit. is not the best answer, because the regulators' inspection visit is not relevant to guide the follow-up audit timing. The regulators' inspection visit is an external factor that may or may not coincide with the internal follow-up audit schedule. The follow-up audit should be based on the internal audit plan and objectives, not on the external audit requirements or expectations12.
