Assessment Objective

Determine if:

• MA-02a.
  • MA-02a.[01] maintenance, repair, and replacement of system components are scheduled in accordance with manufacturer or vendor specifications and/or organizational requirements;
  • MA-02a.[02] maintenance, repair, and replacement of system components are documented in accordance with manufacturer or vendor specifications and/or organizational requirements;
  • MA-02a.[03] records of maintenance, repair, and replacement of system components are reviewed in accordance with manufacturer or vendor specifications and/or organizational requirements;
• MA-02b.
  • MA-02b.[01] all maintenance activities, whether performed on site or remotely and whether the system or system components are serviced on site or removed to another location, are approved;
  • MA-02b.[02] all maintenance activities, whether performed on site or remotely and whether the system or system components are serviced on site or removed to another location, are monitored;
• MA-02c. [Assignment: personnel or roles] is/are required to explicitly approve the removal of the system or system components from organizational facilities for off-site maintenance, repair, or replacement;
• MA-02d. equipment is sanitized to remove [Assignment: information] from associated media prior to removal from organizational facilities for off-site maintenance, repair, or replacement;
• MA-02e. all potentially impacted controls are checked to verify that the controls are still functioning properly following maintenance, repair, or replacement actions;
• MA-02f. [Assignment: information] is included in organizational maintenance records.
