Phase 6 · Ongoing System Maintenance

Keep access, devices, and baselines from drifting as the business changes

Ongoing System Maintenance follows earlier phases when structured care is needed to preserve access control, device discipline, evidence, and operating baselines. Security foundation care — not open-ended monitoring or a managed security retainer.

Why this matters

Teams grow, tools change, and access drifts unless care is deliberate. This phase keeps the Security Foundation layer current through periodic review — so earlier structure does not quietly erode.

Where Ongoing System Maintenance sits

Phase 6 usually follows System Review and Security Foundation work when continuity care is the sensible next step — after earlier phases have established a baseline worth preserving.

What this phase includes

Typical signals

  • onboarding and offboarding gaps reappear as the team grows
  • admin access and shared accounts drift from the last review
  • device baselines or endpoint hygiene fall behind
  • evidence documentation is outdated before the next client or vendor review

Focus

  • Periodic access reviews — who has access, who owns admin roles, and what should change
  • Device and endpoint hygiene — baseline checks so endpoint protection and device discipline stay current
  • Documentation and evidence updates — operating notes and evidence readiness kept aligned with reality
  • Structured care scope — what to review, how often, and what triggers the next pass

Outputs

  • access review findings
  • device and baseline check notes
  • documentation update list
  • structured care scope recommendation

Practical baseline care — not 24/7 threat monitoring, not a managed SOC or incident response retainer, and not penetration testing or compliance certification.

Review rhythm and drift triggers

Structured care on an agreed rhythm — not continuous monitoring or an open-ended retainer.

Typical review rhythm

  • Periodic access reviews — often quarterly, or aligned to team size and change rate
  • Device and endpoint baseline checks when endpoints or protection posture change
  • Documentation and evidence updates before client or vendor security questions

Drift triggers that prompt the next pass

  • New hire, role change, contractor start, or offboarding
  • New admin tool, shared account, or vendor with access to your systems
  • Team growth without an access review since the last baseline
  • Evidence or operating notes clearly out of date versus how work runs today

Ready to scope structured care?

Start with a System Review so maintenance is scoped around real access, device, and evidence priorities. Ongoing care follows only when the diagnosis supports it.
