+MA-04(04) Authentication and Separation of Maintenance Sessions

MA-04(04) Authentication and Separation of Maintenance Sessions

Control

Protect nonlocal maintenance sessions by:
  1. Employing [Assignement: authenticators that are replay resistant] ; and
  2. Separating the maintenance sessions from other network sessions with the system by either:
    1. Physically separated communications paths; or
    2. Logically separated communications paths.

Discussion

Communications paths can be logically separated using encryption.

Assessment Objective

  1. nonlocal maintenance sessions are protected by employing [Assignement: authenticators that are replay resistant];
    1. nonlocal maintenance sessions are protected by separating maintenance sessions from other network sessions with the system by physically separated communication paths; or
    2. nonlocal maintenance sessions are protected by logically separated communication paths.

Assessment Method

Examine

Maintenance policy procedures addressing nonlocal system maintenance system design documentation system configuration settings and associated documentation maintenance records audit records system security plan other relevant documents or records

Interview

Organizational personnel with system maintenance responsibilities network engineers organizational personnel with information security responsibilities system/network administrators
