A company filed a complaint with its IT service provider after the company discovered the service provider's external audit team had access to some of the company's confidential information. Which of the following is the most likely reason the company filed the complaint?

While a Memorandum of Understanding (MOU) with basic clauses might indicate a lack of thoroughness in the agreement, it does not directly address the issue of confidentiality. An MOU typically outlines the intentions and general agreements between parties but does not specifically govern the handling of confidential information like an NDA would.

The Statement of Work (SOW) outlines specific deliverables and services to be provided but does not inherently protect confidential information. The absence of an agreed SOW might lead to confusion about services rendered, but it does not directly relate to the unauthorized access of confidential data by the audit team.

A Work Order (WO) describes specific tasks or jobs to be completed, but like an SOW, it does not serve to safeguard confidential information. Lack of mutual approval on a WO may affect project execution but does not have a direct bearing on the confidentiality of sensitive data shared with the service provider.
