- A named organizational role—and the individual or group filling it—accountable for the installation, configuration, maintenance, and day-to-day operability of an information system or network on behalf of the organization. The role carries responsibility for overseeing day-to-day operability of a computer system or network, and it normally carries special privileges including access to the protection state and software of the system. In security and compliance frameworks, the role is distinguished from ordinary users and from governance roles (such as the authorizing official or CISO) by its hands-on technical custody: the system administrator implements approved secure baseline configurations, incorporates secure configuration settings for IT products, and conducts or assists with configuration monitoring activities. Authority documents enumerate it alongside other named organizational roles—such as human resource managers—because its elevated privileges and operational access make it a key control point for access management, configuration control, and policy enforcement; CNSSI 4009-2022 frames the role as the individual responsible for the installation and maintenance of an information system, providing effective utilization, adequate security parameters, and sound implementation of established policy and procedures.Drafted by the propose-term web lookup (PD-018); a curator confirms or replaces it.
