Assessment Objective

Determine if:

• MA-04a.
  • MA-04a.[01] nonlocal maintenance and diagnostic activities are approved;
  • MA-04a.[02] nonlocal maintenance and diagnostic activities are monitored;
• MA-04b.
  • MA-04b.[01] the use of nonlocal maintenance and diagnostic tools are allowed only as consistent with organizational policy;
  • MA-04b.[02] the use of nonlocal maintenance and diagnostic tools are documented in the security plan for the system;
• MA-04c. strong authentication is employed in the establishment of nonlocal maintenance and diagnostic sessions;
• MA-04d. records for nonlocal maintenance and diagnostic activities are maintained;
• MA-04e.
  • MA-04e.[01] session connections are terminated when nonlocal maintenance is completed;
  • MA-04e.[02] network connections are terminated when nonlocal maintenance is completed.
