What are the responsibilities of a system owner Each correct answer represents a complete solution. Choose all that apply.

A system owner is a senior-level manager responsible for the information system throughout its lifecycle. This includes integrating security requirements into procurement and development projects (A). They are ultimately accountable for ensuring that the controls implemented provide adequate security, which involves overseeing configurations, access controls, and other protective measures (C). The owner is also responsible for the system's ongoing security posture, which includes ensuring vulnerability assessments are conducted and that findings are appropriately reported to relevant teams (D). These responsibilities reflect the owner's role in governance, risk management, and operational oversight for the system.

B. This statement is less precise. While the system owner is accountable, the direct implementation or verification that controls are simply "in place" is often delegated to a custodian or system administrator. Option C better describes the owner's responsibility for the effectiveness and adequacy of the security provided.

1. NIST Special Publication 800-18

Rev. 1

Guide for Developing Security Plans for Federal Information Systems. Section 3.3

"Roles and Responsibilities

" defines the Information System Owner as the "organizational official responsible for the procurement

development

integration

modification

operation

maintenance

and disposal of an information system." This directly supports option A and provides the foundation for options C and D.

2. NIST Special Publication 800-53

Rev. 5

Security and Privacy Controls for Information Systems and Organizations. Appendix D

Section D.2.10

"System Owner

" outlines responsibilities including: "ensuring that the security controls are implemented and that the controls are assessed for effectiveness." This supports the focus on adequacy in option C and the assessment responsibility in option D.

3. NIST Special Publication 800-37

Rev. 2

Risk Management Framework for Information Systems and Organizations. Table F-5

"Information Owner/Steward and System Owner Roles and Responsibilities

" specifies that the system owner is responsible for "ensuring that security requirements are included in acquisition contracts" (supporting A) and "managing and controlling changes to the system" (supporting C).
