03.07.04: Nonlocal Maintenance

Discussion:

Nonlocal maintenance and diagnostic activities are conducted by individuals who communicate through an external or internal network. Local maintenance and diagnostic activities are carried out by individuals who are physically present at the location of the system and not communicating across a network connection. Authentication techniques used to establish nonlocal maintenance and diagnostic sessions reflect the requirements in 03.05.01.
