Which organizational official is responsible for the procurement, development, integration, modification, operation, maintenance, and disposal of an information system? Response:

An Information System Security Engineer (ISSE) focuses on the security aspects of design, implementation, and operations, not the overall system ownership.

A Chief Information Officer (CIO) oversees the entire organization's information technology strategy and operations, a broader role than specific system ownership.

The Information System Owner (ISO) is accountable for the management, acquisition, and full lifecycle of an information system, encompassing procurement, development, integration, modification, operation, maintenance, and disposal. They ensure the system meets its mission needs while adhering to security policies.

An Information Security Architect designs the security framework and controls, but does not own the full lifecycle responsibility for a specific system.
