What is the function of the IAO?

• A. Information Accreditation Officer, oversee data integrity
• B. Information Access Officer, manage access control
• C. Interagency Analysis Officer, coordinate with allies
• D. Information Assurance Officer, implement/maintain network security

Answer: (D)

The essential idea is safeguarding information systems through information assurance. The Information Assurance Officer is charged with implementing and maintaining security for information systems, which includes applying security controls, managing risk, protecting data, and keeping networks secure. This role also involves monitoring for threats, responding to incidents, and supporting continuity of operations to keep information available and trustworthy. The other roles described differ in focus: overseeing data integrity and accreditation, managing who can access systems, or coordinating with partners—none of which fully captures the ongoing security responsibilities of an Information Assurance Officer.
