How often should the Statements of Standards for Attestation Engagements-16 (SSAE16)/International Standard on Assurance Engagements...

 Explanation:

SSAE16/ISAE3402 reports should be reviewed annually to evaluate vendor compliance with agreed-upon controls and identify any risks or gaps in their processes.

Annual reviews align with standard auditing practices and vendor contract expectations.

 Why Other Options Are Incorrect:

A. Quarterly: This frequency is unnecessary unless specific risks require closer monitoring.

B. Semi-annually: Twice a year reviews may be overkill for standard vendor operations.

C. Bi-annually: The term "bi-annually" could mean either twice a year or every two years, leading to ambiguity and potential non-compliance.

 EC-Council CISO Reference:

Vendor management processes, including the annual review of attestation reports, are a key component of the CISO role.
