Title

Nonlocal Maintenance

Control

a. Approve and monitor nonlocal maintenance and diagnostic activities.
b. Implement multi-factor authentication and replay resistance in the establishment of nonlocal maintenance and diagnostic sessions.
c. Terminate session and network connections when nonlocal maintenance is completed.

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 [](#/cprt/framework/version/SP_800_171_3_0_0/home?element=03.05.01) 03.05.01.

Assessment objective

nonlocal maintenance and diagnostic activities are approved.
