Maintenance Supervision

NIST indicates that maintenance supervision applies to individuals performing hardware or software maintenance on organizational information systems. Technical competence of supervising individuals relates to the maintenance performed on the information systems while having required access authorizations refers to maintenance on and near the systems. Individuals not previously identified as authorized maintenance personnel, such as information technology manufacturers, vendors, systems integrators, and consultants, may require privileged access to organizational information systems, for example, when required to conduct maintenance activities with little or no notice. The organization establishes a process for maintenance personnel authorization and maintains a list of authorized maintenance organizations or personnel. Ensure that non-escorted personnel performing maintenance on the information system have required access authorizations and designates organizational personnel with required access authorizations and technical competence to supervise the maintenance activities of personnel who do not possess the required access authorizations.
