Maintenance (MA) Family
Also known as: MA family
The MA family covers 6 NIST SP 800-171 requirements governing system maintenance, maintenance personnel, and remote maintenance controls.
The Maintenance (MA) family contains 6 NIST SP 800-171 Rev 2 security requirements covering how the contractor performs and oversees maintenance on in-scope systems.
Requirements include performing maintenance on system components (MA.L2-3.7.1), providing controls on maintenance tools (MA.L2-3.7.2), ensuring sanitization of equipment removed for off-site maintenance (MA.L2-3.7.3), checking media containing diagnostic and test programs (MA.L2-3.7.4), requiring multifactor authentication for nonlocal maintenance sessions (MA.L2-3.7.5), and supervising maintenance activities of personnel without required access authorization (MA.L2-3.7.6).
The MA family becomes particularly relevant when the contractor outsources hardware maintenance or relies on remote support tools.
