MA-4(2): Document Nonlocal Maintenance

Nonlocal maintenance is one of those requirements that fails in practice for a simple reason: the work happens quickly, under pressure, and across organizational lines (IT ops, SecOps, third parties, and cloud providers). MA-4(2): document nonlocal maintenance requirement exists to make that work inspectable after the fact, so you can prove who did what, on which system, when, why, and with what outcome. ¹

For a Compliance Officer, CCO, or GRC lead, the fastest path is to turn “nonlocal maintenance” into a defined maintenance scenario with required fields, required approvals, and required evidence. Then you enforce that it always flows through the same mechanisms: ticketing, approved remote access paths, and post-maintenance review. You are building a record that supports accountability and reduces the risk of untracked changes, unauthorized access, or persistent remote connectivity that becomes an attack path.

This page gives requirement-level implementation guidance: plain-English meaning, who it applies to, a step-by-step operating procedure, what evidence to retain, common audit questions, and a practical execution plan.

Regulatory text

Excerpt (as provided): “NIST SP 800-53 control MA-4.2.” ²

Control summary (as provided): “MA-4(2): Document Nonlocal Maintenance.” ²

What the operator must do:
You must document nonlocal maintenance activities for in-scope systems. In practical terms, when maintenance is performed from a remote location or by personnel not physically present with the system, you need a complete, reviewable record that ties the activity to authorization, the system worked on, what was done, and the outcome. This documentation must be retained as part of your maintenance records and be retrievable for assessments. ¹

Plain-English interpretation

Documenting nonlocal maintenance means you cannot treat remote maintenance like an informal chat and a quick login. If someone patches, configures, diagnoses, or repairs a system from outside your controlled space (including third-party support), you capture:

• the business justification,
• who performed the work (and under whose authorization),
• the access method used,
• the exact systems/components touched,
• what changed (or confirmation of no change),
• start/end timing, and
• validation that the system returned to a secure, operational state.

Auditors look for two things: (1) completeness (you didn’t miss events), and (2) traceability (your record links to access logs and configuration/change history). ³

Who it applies to

Entity types (common scoping):

• Federal information systems
• Contractor systems handling federal data (for example, environments supporting federal contracts) ²

Operational contexts where MA-4(2) shows up:

• Remote OEM or integrator support sessions to troubleshoot appliances, network gear, or industrial/OT components.
• Managed service provider (MSP) administration of servers, endpoints, databases, or identity platforms.
• Cloud-admin maintenance where privileged actions are taken from outside your facilities, including by third parties.
• Emergency fixes performed by on-call admins from home, hotels, or offsite locations.

In-scope assets (typical):

• Systems subject to your NIST 800-53 control baseline and your system security plan scope.
• Maintenance tooling used to reach those systems (jump hosts, remote management interfaces, privileged access tools). ³

What you actually need to do (step-by-step)

1) Define “nonlocal maintenance” for your environment

Create a short definition and examples in a standard (policy/procedure) that your operators can apply without debate. Include:

• Remote interactive sessions (SSH/RDP/console),
• Remote diagnostics and firmware updates,
• Third-party “support tunnel” sessions,
• Offsite work performed on your behalf. ³

Decision rule to publish internally:
If maintenance is performed without the maintainer being physically present in your controlled facility or via remote connectivity, treat it as nonlocal maintenance and document it.

2) Assign control ownership and RACI

Minimum roles:

• Control owner: accountable for MA-4(2) design and evidence readiness.
• IT operations owner: ensures the ticketing and maintenance workflow captures required fields.
• Security owner: ensures remote access paths are approved and logs are retained.
• Third-party manager (if applicable): ensures contracts/SOWs require documentation inputs from the third party.

Map these responsibilities in your GRC system so evidence requests do not bounce between teams. ³

3) Standardize the nonlocal maintenance record (template)

Build a Nonlocal Maintenance Log (or required ticket fields) that captures:

Field	What “good” looks like
Maintenance request ID	Ticket number, change ID, or incident ID
System/component	Asset ID/hostname, environment, data sensitivity
Maintenance type	Patch, repair, diagnostic, config, firmware, other
Performer	Named individual, employer/third party, role
Authorization	Approver name, approval timestamp, scope granted
Access method	VPN + jump host, PAM session, vendor portal, console
Start/end	Time window for the activity (planned vs actual)
Actions taken	Commands/steps summary, files changed, packages applied
Outcome	Success/failure, validation checks, rollback notes
Artifacts	Links to logs, session recordings, screenshots, work notes

Keep this as a controlled template. Do not rely on free-text notes only.

4) Force all nonlocal maintenance through a controlled workflow

Operational controls that make documentation “default”:

• Ticket required before access (normal operations) or ticket created immediately after (true emergencies).
• Remote access must use approved paths (VPN/PAM/jump host), not ad-hoc direct inbound access.
• Time-bounded access where possible (request a window; disable after close). ³

If a third party performs the maintenance, require the third party to provide the same documentation elements, and attach their work record to your ticket.

5) Reconcile documentation against independent technical records

This is the step many teams skip and auditors ask for.

On a recurring basis, sample nonlocal maintenance events and reconcile:

• Ticket fields vs remote access logs (who connected, from where, when).
• Ticket fields vs configuration/change records (what changed).
• Ticket fields vs system logs (service restarts, patch installation events).

Your goal: prove the documentation is complete and not “best effort.”

6) Close-out review and evidence packaging

Require a close-out checklist before ticket closure:

• Access removed/expired (if temporary)
• Validation completed (service health, security checks)
• Artifacts attached (logs, approvals, session record link)
• Any follow-up risk accepted or escalated

Then package evidence so you can answer an assessor request in minutes.

7) Automate collection where you can

You do not need new tools to start, but automation reduces gaps:

• Auto-tag tickets as “nonlocal maintenance” when a remote session is opened.
• Auto-attach session IDs from PAM tools.
• Auto-export remote access logs to your SIEM and retain per your logging standard.

Daydream fits naturally here by mapping MA-4(2) to an owner, a repeatable procedure, and a recurring evidence set, so you can show control design and operating effectiveness without re-building the same packet each audit. ²

Required evidence and artifacts to retain

Keep evidence in a way that supports sampling and traceability.

Core artifacts:

• Nonlocal maintenance policy/procedure (definition, workflow, required fields). ³
• Completed maintenance records (tickets/changes/incidents) marked as nonlocal maintenance. ²
• Approval evidence (manager/system owner/security approval as applicable).
• Remote access logs for the relevant period (VPN, jump host, PAM session logs).
• Change evidence (change record, config management diffs, patch reports).
• Post-maintenance validation record (test results, monitoring confirmation).

If a third party performed the work:

• Contract/SOW language requiring maintenance documentation and cooperation in audits.
• Third-party work notes or service report attached to your ticket.

Common exam/audit questions and hangups

Expect these questions and prep answers with artifacts:

1. Show me how you define nonlocal maintenance and how staff know when it applies.
2. Provide a sample of nonlocal maintenance events and the associated documentation.
3. How do you prevent undocumented remote support sessions?
4. How do you know the documented maintainer is the person who actually accessed the system? (They will ask for access logs.)
5. How do you handle emergencies? (They want to see after-the-fact documentation and approvals.)
6. What about cloud provider maintenance or managed services? (You still need your record, plus third-party inputs where available.)

Hangup to avoid: handing over a ticket with vague notes and no linkage to access logs.

Frequent implementation mistakes and how to avoid them

• Mistake: treating “documentation” as a narrative paragraph.
  Fix: required structured fields plus attached artifacts.

• Mistake: missing third-party maintenance.
  Fix: add a contract requirement and require tickets for third-party sessions; route all third-party access through your approved remote access path where possible.

• Mistake: no reconciliation.
  Fix: run a lightweight monthly check: pick a few remote sessions from logs and confirm each has a matching maintenance record.

• Mistake: emergency exception becomes the norm.
  Fix: define an emergency path with stricter after-action requirements (who authorized, why it was emergency, what was done, validation).

• Mistake: documentation stored in email threads.
  Fix: make the ticket the system of record and attach emails as artifacts, not the other way around.

Enforcement context and risk implications

No public enforcement cases were provided in the source catalog for this requirement, so this page focuses on assessment and operational risk.

Risk implications if you cannot document nonlocal maintenance:

• You cannot prove remote privileged activity was authorized and scoped.
• You increase the chance of untracked configuration drift and insecure changes.
• You make incident response harder because you cannot distinguish maintenance activity from adversary activity. ³

Assessors often treat missing documentation as a control failure even if the maintenance was performed safely, because the requirement is explicitly about recordkeeping and accountability. ²

Practical 30/60/90-day execution plan

Next 30 days (stand up the minimum viable control)

• Name the MA-4(2) control owner and publish a one-page nonlocal maintenance procedure aligned to MA-4(2). ³
• Add required fields to your ticketing/change tool (or publish a mandatory template) and train on-call staff and service desk triage.
• Identify approved remote access paths and require that maintenance uses them.

Days 31–60 (make it provable)

• Start capturing a repeatable evidence packet: sample completed tickets, approvals, and matching access logs.
• Add third-party requirements: contract language, support process, and ticketing expectations.
• Build a reconciliation check between remote access logs and tickets, and remediate misses.

Days 61–90 (make it durable)

• Add close-out reviews and an exception process for emergencies.
• Automate evidence collection where feasible (PAM session IDs in tickets, SIEM retention, standardized exports).
• Operationalize reporting: a simple dashboard of nonlocal maintenance events, exceptions, and overdue documentation.

Daydream can reduce the overhead by keeping the MA-4(2) procedure, owner mapping, and evidence checklist in one place, so quarterly sampling and audit requests turn into a repeatable workflow instead of a scramble. ²

Frequently Asked Questions

What counts as “nonlocal” maintenance in a cloud-first environment?

Treat maintenance as nonlocal when the maintainer is not physically present with the system and performs actions through remote connectivity. For cloud consoles and managed services, document the privileged actions your staff or third parties perform and retain the supporting access records. ³

Do I need session recording to satisfy MA-4(2)?

MA-4(2) focuses on documentation, so session recording is a strong artifact but not the only way. If you cannot record sessions, keep structured tickets, approvals, and independent access logs that corroborate the maintenance record. ³

How do we handle emergency break-fix work done by on-call engineers?

Allow emergency access, but require rapid after-the-fact documentation in the same system of record, including who authorized it, what was done, and validation steps. Track emergencies as exceptions and review them for patterns. ³

A third party refuses to give detailed work notes. What’s the practical minimum?

You still need a maintenance record that identifies the third party personnel (or team), authorization, access method, systems touched, and outcome, plus your own access logs that corroborate the activity. Update contracts/SOWs so documentation is a deliverable for support. ³

How do we prove completeness, not just that we documented a few events?

Reconcile independent remote access logs against tickets and investigate unmatched sessions. Document the reconciliation as a recurring control activity and retain results. ³

Where should the documentation live: ITSM tickets, GRC tool, or both?

Keep the ticket/change record as the system of record for the event and store an evidence index in your GRC tool that points to the underlying artifacts. Daydream is well-suited for the mapping and recurring evidence checklist so you can produce consistent audit packets without duplicating operational records. ²
