In evaluating programmed controls over password management, which of the following would the IS auditor MOST likely rely on?

In the context of evaluating programmed controls over password management, relying on a validity check is essential because it ensures that the values entered into the system meet specific criteria, which is critical for maintaining security standards. Validity checks confirm whether the data entered falls within predetermined acceptable ranges or formats, which is particularly important for passwords, as they often have specific requirements regarding length, complexity, and allowed characters. This means that the validity check helps ensure that passwords meet organizational security policies and reduces the potential for weak passwords.

In the context of password management, other checks like a size check, hash total, or field check serve different purposes. A size check verifies if the input is of an expected length but does not assess the password's complexity. A hash total is generally used for data integrity verification rather than input validation. Lastly, a field check ensures that the input adheres to data type requirements, but might not validate specific content rules related to password security. Therefore, a validity check is the most suitable control for ensuring that the passwords created align with established security criteria.
